To understand how the Monitor works, it is best to know what each circuit
does and how each circuit relates to the other circuits. The Block Diagram is
presented in a simplified view and a comprehensive view to accomplish the goal of
understanding the whole unit. Once the general picture is clear, the complexity of
each circuit will be easier to understand.
The Circuit Description is also written in two views, a simplified view and a
detailed view to help give the reader a clear understanding of what each
component does. This understanding is most helpful for the more complex
problems or multiple problems that sometimes occur.
The power supply trouble shooting section describes methods used to power up
various monitor circuits, when there is a fault in the monitor, which disables the
power supply.
The appendix includes; filament voltage test, convergence procedure,
replacement parts purchase order form, degaussing coil attachment specification,
high pot test, wire routing drawing, production assembly drawings (PADs), C, I, J,
& K film resistor arrays and a parts list addendum. The parts list addendum is
used to add new information describing part changes. Tables, suitable for pasting
on these pages, will be published as new variations of the XX93 monitors are
produced.

This block diagram gives a broad view of the circuit organization of the 1493,
1793, 1993, 2093, 2793, and 3693 monitors. The blocks with the bold outline
represent circuits which provide these monitors with a wide range of
operating conditions without the need for adjustment.
The video interface circuit can be programmed to accept; +Analog AC or
DC coupled, -Analog, and 4 line TTL. The M. GAIN or contrast control is
located on the remote control board.
The auto bias circuit eliminates the need for the color setup procedure.
This circuit is designed to actively compensate for picture tube drift which
normally causes unbalanced color. The auto bias circuit also adjusts the
CRT gain to compensate for gain loss with age.
The horizontal size control circuit permits the horizontal size to be adjusted
from a remote control board. This circuit is also used to compensate for
pincushion distortion and blooming. Anti-blooming is accomplished by
correcting horizontal size variations which are caused by the additional load
on the flyback transformer under high beam current conditions.
Careful reading of all the information presented in this manual is a good
way to learn how to repair the CERONIX monitor.

A
The Video Interface is designed around a custom IC and will accept DC or AC
coupled positive analog video signals. It can also be used with negative analog
and 4 line TTL. This IC has a built in multiplier circuit for the master gain
control and blanking functions. Resistors are used to protect the IC and to set
the gain. The programmed gain is dependent on the input signal amplitude
except with the TTL mode. Solder jumpers and component substations are used
to program the Video Interface for the type of input signal to be received. The
output of the IC drives the video amplifiers. This drive is a current where 0 mA
is black and 10 mA is a saturated color.
B
The Video Amplifiers are of the push pull type. They are built partly on thick
films and partly on the video PCB. Spreading out the amplifier reduces the
component heat and improves the life of the unit. The bandwidth is 25 MHz with
40Vp-p output. The rise and fall times are 20nS.
C
The Beam Current Feedback circuit directs most of the beam current of each
amplifier to the beam current buffer. The only time this current is measured, by
the auto bias circuit, is during the time of the three faint lines at the top of the
screen and three lines thereafter. The CRT auto bias circuit is designed to adjust
the video amplifier bias voltage such that the beam current of each of the three
guns is set to a specific programmed value.
D
The Beam Current Buffer converts the, high impedance low current, beam
current signal into a low impedance voltage. This voltage is applied to the auto
bias IC through a 200 ohm resistor. After the three lines of beam current are
measured, the program pulse from the auto bias IC, produces a voltage drop
across this 200 ohm resistor that equals the amplitude of the beam current
voltage.
9
E
The CRT Auto Bias IC is a combination of digital and analog circuitry. The
digital part is a counter and control logic which steps the analog circuits through a
sequence of sample and hold conditions. The analog part uses a transconductance
amplifier to control the voltage on a 10uF capacitor (one per gun). This voltage is
buffered and sent to the video amplifiers as the bias voltage. In monitors without
CRT auto bias, this voltage is adjusted manually using a setup procedure to set
the color balance. With CRT auto bias, the color balance is set during the end of
each vertical blanking time.
The control sequence is:
1.
The cycle starts with a sync pulse from the vertical oscillator (15KHz)
or from the vertical sync delay. 15H later the grid pulse starts.
2.
The grid pulse on G1 causes cathode current which can be seen as the
three faint white lines at the top of the screen. This cathode current is
transmitted by the beam current feedback to the beam current buffer
where it is converted to a voltage and applied to the CRT auto bias
input pin. At this time the CRT auto bias IC outputs a reference
voltage at its input pin which sets the voltage across the coupling
capacitor. This coupling capacitor voltage is directly dependent on
beam current.
3.
After the grid pulse is over, the program pulse matches the voltage
from the beam current buffer. If the voltage from the beam current
buffer, during the grid pulse, is the same as the voltage from the
program pulse, the bias is correct and no bias adjustment is made for
that vertical cycle.
F
The timing of the auto bias IC is synchronized to the vertical oscillator and the
flyback pulses. For horizontal frequencies higher than 15.7KHz a Vertical Sync
Delay may be needed to position the grid pulse, generated 3 gray lines, at the top
of the screen. The need for the delay circuit is dependent on the particular CRT
vertical retrace time.
G
The aging of the picture tube (CRT) not only affects the balance of the cathode
cutoff voltage, which is corrected by the auto bias circuit, but it also affects the
gain of the CRT. The Auto Bright circuit actively corrects for CRT gain changes
by sensing any common bias voltage change, from the auto bias circuit, and
adjusts the screen voltage to hold the average bias voltage constant. The lower
adjustment on the flyback transformer which is the screen voltage, is used to set
the auto bright voltage to the center of its range. Therefore, the auto bright
circuits sets up a second control feedback loop to reduce picture variation due to
CRT aging. The auto bright circuit is also used to turn off the beam current when
the monitor power is turned off.
10
H
The CRT for the 1493, 1793 and 2093 monitors have a 90° deflection angle. The
1993 incorporates 100° while the 2793 CRT has 110° and the 3693 has 111°
deflection angles. These picture tubes have integral implosion protection and a
EHT of 25KV.
H1
The Vertical Dynamic Focus amplifies the parabolic waveform across the
vertical coupling capacitor from about 3Vp-p to about 200Vp-p, depending on CRT
requirements. This waveform sharpens the top and bottom portion of the raster
on dual focus CRT's.
H2
The Horizontal Dynamic Focus amplifies the parabolic waveform across the
horizontal coupling capacitor, using a transformer to produce 300Vp-p output from
an input that is about 33Vp-p. This waveform is added to the vertical dynamic
waveform and sharpens the right and left sides of the raster.
I
Blanking is accomplished by setting the gain of the interface IC to zero during
blank time. The Horizontal Blanking pulse is generated by amplifying the flyback
pulse. The Vertical Blanking pulse is started by the vertical oscillator one shot
and ended by the counter in the auto bias IC via the "bias out" pulse. The Master
Gain control, located on the remote PCB, sets the gain of the video signal when
blanking is not active. The Beam Current Limiter circuit, which is designed to
keep the FBT from overloading, will reduce the video gain if the maximum
average beam current is exceeded. Also, the beam current is reduced if the FBT
approaches maximum operating temperature.
J
The Sync Interface can accept separate or composite sync. Two comparators are
used to receive sync, one for vertical sync and the other for horizontal sync.
Resistor dividers are used to protect the comparator IC from over voltage damage.
For customers who do not require interlace, an additional vertical sync
stabilization circuit is included. This circuit synchronizes the vertical sync to the
horizontal cycle.
K
The Vertical Oscillator generates the vertical free running frequency when no
vertical sync is present. When sync is applied, the vertical oscillator synchronizes
to the leading edge of the sync pulse.
L
The Vertical Control & Output circuit consists of:
1.
2.
3.
4.
11
One shot.
Ramp generator.
Vertical drive.
Vertical output.
The sync pulse from the LA7851 triggers a one shot in the LA7838 which clamps
the vertical ramp generation capacitor to 5V during the first half of vertical
retrace. The ramp generation capacitor then charges via a constant current set by
an external resistor. This resistor is connected to the V SIZE pot, located on the
remote control board, for the vertical size adjustment. The vertical drive is a
differential amplifier which compares the ramp voltage to the yoke return
feedback current. The yoke feedback current and voltage circuits are used to set
the vertical linearity. The vertical Output is a power driver, with thermal
protection, which drives the vertical deflection yoke. It also has a special pump up
circuit which doubles the output voltage during vertical retrace. This voltage
doubler also increases the efficiency of the circuit since the high retrace voltage is
not present across the power driver during the trace time.
M
The Horizontal Control incorporates a variable sync delay and a phase locked
loop to generate the horizontal timing. The H POS. adjustment, on the remote
control board, sets the sync delay time which controls the picture position. The
phase locked loop uses the flyback pulse to generate a sawtooth wave which is
gated with the delayed sync pulse to control the horizontal oscillator.
N
The Horizontal Driver supplies the high base current necessary to drive the
horizontal output transistor which has a beta as low as three. A transformer is
used to step up the current from the driver circuit and also protects the horizontal
output transistor from a continuous turned on state. A special clamp circuit is
connected to the transformer which reduces the turnoff time of the horizontal
output transistor for reduced power dissipation.
O
The Horizontal Output transistor is mounted to the rear frame which acts as a
heat sink. The collector conducts the 900 volt primary flyback pulses which should
not be measured unless the equipment is specifically designed to withstand this
type of stress. A linear ramp current is produced in the horizontal yoke by the
conduction of the horizontal output transistor (trace time). A fast current reversal
(retrace time) is achieved by the high voltage pulse that follows the turn off of the
horizontal output transistor. This pulse is due to the inductive action of the yoke
and flyback transformer.
P
The main function of the Flyback Transformer (FBT) is to generate a 25,000 volt
(EHT) potential for the anode of the picture tube. This voltage times the beam
current is the power that lights up the phosphor on the face of the picture tube.
At 1.5mA beam current, for the 2793 monitor, the FBT is producing almost 38
watts of high voltage power. The FBT also sources the focus voltage, screen grid
voltage, filament power, and has two more secondaries which are used for control
functions. The FBT has a built in high voltage load resistor which stabilizes the
EHT, for the low beam current condition. This resistor also discharges the EHT,
when the monitor is turned off, which improves the safety of handling the
monitor.

The horizontal size control circuit sums the four signals at one node plus the
feedback from the diode modulator to drive a switching mode power driver. The
output of the power driver is then connected to the diode modulator through an
inductor to complete the control loop.
S
The Diode Modulator is a series element of the horizontal tuned circuit. It forms
a node between GND and the normal yoke return circuit. If this node is shorted to
GND, the result is maximum horizontal size. Forward current in the diode
modulator, at the start of retrace, keeps the node voltage clamped to ground until
enough current flows from the horizontal tuned circuit to exceed this forward
current. The horizontal size, therefore, is controlled by controlling the current to
this diode via the horizontal size control circuit.
T
A Voltage Doubler is used in the power supply for two reasons:
1. To improve the efficiency of the power supply.
2. To permit 120 volt and 230 volt operation. For the 230 volt
operation the voltage doubler is replaced with a bridge rectifier.

XX93 Monitor Block Diagram.
U
The Switching Regulator is synchronized to the horizontal pulse and drives a power
MOSFET. Unlike most regulators that have a common GND, this power supply has a common
V+ and current is supplied from V- to GND. The MOSFET is connected to V– and signal
ground (GND) through a transformer which is used as an inductor for series switch mode
regulation. An operational amplifier, voltage reference, comparator, and oscillator in the power
supply controller IC are used to accomplished regulation by means of pulse width modulation.
The transformer has two taps on the main winding which are used to generate the +16 volt
and +24 volt supplies. It also has a secondary which is referenced to V- and supplies the power
supply. Since the power supply is generating its own power, a special start up circuit is built
into the power supply controller IC that delays start up until the capacitor which supplies the
IC is charged up enough to furnish the current to start the power supply. This capacitor is
charged with current through a high value resistor from the raw dc supply. This self sustaining
action is why the power supply chirps when an overload or underload occurs. Additional
secondaries to drive the horizontal raster shift circuit and the video amplifiers are also included
in the power transformer.

The Load consists primarily of the horizontal flyback circuit. The power supply will not
operate without the load since the voltage that sustains the power supply comes from a
secondary in the power transformer and depends on some primary current to generate

(IN GAME)
The Degaussing circuit is connected across the isolated AC line. A posistor is used to allow a
large current to flow, in the degaussing coil, on power up. This current is then gradually
reduced by the increased temperature of the positive temperature coefficient thermistor in the
posistor. A relay is used to short the degaussing coil after the degaussing operation. This
greatly reduces posistor residual current in the degaussing coil. When repairing a monitor, the
degaussing coil should be unplugged, to avoid possible damage to the degaussing coil shorting
relay.

Description
6,800pF ±5%, 100V, Film
CAUTION:
CERONIX XX93 Monitors MUST USE AN APPROVED ISOLATION
TRANSFORMER.
The monitor chassis must be connected to earth ground via a common connection
in the system which contains the monitor.
X-RAY NOTE:
X-radiation is produced by electrons colliding with the phosphor and shadow mask at the
front of the picture tube. The X-radiation emanating from the front of the picture tube is
highly reduced due to the shielding affect of the leaded glass face.
It is also produced at the anode bulb contact. The X-radiation emanating from the anode bulb
contact is much higher than from the face due to less shielding.
X-radiation is directly proportional to beam current. It doubles for each 1.3KV increase of
the EHT voltage at the face and also doubles for each 3KV increase of the EHT at the anode
bulb contact.
From this information, it should be noted that when servicing monitor electronics, where the
back of the picture tube is facing the service person, that the beam current should be turned
down to avoid excessive exposure.
Due to the increase in X-Radiation emission with increase of EHT voltage, it is important that
the EHT voltage is checked.
To measure the EHT voltage: Connect the (-) lead of a volt meter to the monitor chassis so
that a reliable connection is made. Connect a high voltage probe to the (+) input of the meter
and at the anode contact of the picture tube.
The EHT should not exceed 26KV at 0 beam current.

VORSICHT:
MONITOREN CERONIX XX93 MÜSSEN EINEN ANERKANNTEN
LOKALISIERUNG TRANSFORMATOR BENUTZEN.
Das Monitorchassis muß an die Masse angeschlossen werden, die über einen
allgemeinen Anschluß im System gerieben wird, das den Monitor enthält.
RöNTGENSTRAHLANMERKUNG:
X-Strahlung wird durch die Elektronen produziert, die mit der Phosphor- und
Schattenschablone an der Frontseite des Abbildung Gefäßes zusammenstoßen. Die
X-Strahlung, die von der Frontseite des Abbildung Gefäßes ausströmt, liegt in hohem Grade
an der Abschirmung beeinflussen vom verbleiten Glasgesicht verringertes. Sie wird auch am
Anode Birne Kontakt produziert. Die X-Strahlung, die vom Anode Birne Kontakt ausströmt,
ist viel höher als vom Gesicht, das zu weniger abschirmen passend ist. X-Strahlung ist direkt
zum Lichtstrahlstrom proportional. Sie verdoppelt für jede Zunahme 1.3KV der
EHT-Spannung am Gesicht und verdoppelt auch für jede Zunahme 3KV des EHT am Anode
Birne Kontakt.
Von diesen Informationen sollte es beachtet werden daß, wenn man Monitorelektronik
instandhält, in der die Rückseite des Abbildung Gefäßes die Service-Person gegenüberstellt, daß
der Lichtstrahlstrom unten gedreht werden sollte, um übermäßige Berührung zu vermeiden.
Wegen der Zunahme der X-Radiationemission mit Zunahme der EHT-Spannung, ist es wichtig,
daß die EHT-Spannung überprüft wird.
Die EHT-Spannung messen: Schließen Sie die (-) Leitung eines Voltmeßinstruments an das
Monitorchassis an, damit eine zuverlässige Beziehung hergestellt wird. Schließen Sie eine
Hochspannungsprüfspitze an den (+) Input des Meßinstruments und am Anode Kontakt des
Abbildung Gefäßes an.
Das EHT sollte nicht 26KV bei 0 Lichtstrahlstrom übersteigen.

In the positive analog mode, a bias current of
.6mA flows to the input pin 2. This current is
set by resistor 261 at the +Analog Enable
input pin 11. The .6mA produces a voltage,
across the parallel resistance of the game and
288 plus resistor 278
278 , at pin 2. If the
288
external source resistance is 75 ohms, the black
level voltage at pin 2 is .18V for 15KHz and
.07V for the 31KHz.

The input termination resistor 288

The normal saturated color is set at .70

In each of the video interface circuit configurations,
current from the interface circuit is converted to a
voltage at the CRT cathodes. The simplest current
path is accomplished by the negative analog video
interface configuration.
The voltage drop across the input resistors 278
278 and
, for the red channel, is the current which drives
the video amplifiers when the video gain line is at
8.2 volts. For a lower gain line voltage, part of the
current is directed to the +12 volt line. During blanking
all the input current flows to the +12 volt line.

and there is no video amplifier output. For the red and
green channels, a 1 volt change at the video input
produces a 15 volt change at the video amplifier output.
For the blue channel this change is 18 volts but resistor
265
265 subtracts the equivalence of .6 volts from the input
which results in the same saturated color as the red and
green channels.
271 , 270
The clamp diodes 271
270 , & 268
268 limit the
maximum current to the video amplifiers. This avoids
over driving the video amplifiers when undershoots at
the input cables are present. The clamp reference
273 , and buffer
voltage is set by resistors 272 , 273
274 . Load resistor 275 stabilizes this
transistor 274
buffered clamp voltage.

Resistors 223 , 242 , & 231
across the gain resistors to offset the voltage drop
caused by the .6mA bias current across the input and
protection resistors. +12 volts to these resistors
produces a fixed black level. An optional black level
adjustment may replace the +12V with a range of
0 volts to 11.3 volts. Potentiometer 070
070 is buffered by
transistor 221
221 and resistor 219

adjustment voltage.
The RGB video signals and sync are connected to
the monitor through the video input connector 292

properly, the incoming video must be at the black level
voltage when horizontal sync starts and remain
blanked for at least 4.5uS.
The clamp circuit is dependent on the polarity of
incoming horizontal sync. For separate horizontal
sync, the sync polarity should be positive. For
composite sync, and positive going horizontal sync
pulses, resistor 320
320 (.30” long) is connected to the
inverting horizontal sync comparator which is the same
as separate, positive, horizontal sync. For composite
sync, with negative going horizontal sync pulses,
320 (.45” long) makes the connection to the
resistor 320
noninverting vertical sync comparator. This connection
is valid since the horizontal and vertical sync lines are
connected together for composite sync.
The clamping function is accomplished by turning on
transistor 303
303 at the start of horizontal sync through
the differentiating action of capacitor 316 and resistors
305 & 320 . The collector of this transistor is
305
connected to clamp transistors 311 , 312 , & 313
313
310 , 308
through resistors 310
308 , & 307
307 with pull down

283 at the video input are set to the black level voltage
by the video source.

If the coupling capacitor voltage, on the clamped side,
is high at clamp time, the clamp transistor shorts the
capacitor to GND by normal transistor action. If the
coupling capacitor voltage is low at clamp time the
clamp transistors act as dual diodes to raise the
capacitor voltage to GND, which is the black level
reference for the video input circuit.
The ground referenced video signal is then buffered

278 , 277
277 , & 276
276 . The buffer transistors
are needed to reduce the .6mA bias current, from the
video interface IC, to under 10uA which limits the
coupling capacitor voltage buildup to 2mV during one
horizontal cycle.
Resistor 275
275 and clamp diodes 271
271 , 270
270 , & 268
268
are connected to the coupling capacitors to limit the
voltage buildup when no sync is present. If this limit
did not exist, the monitor would show excessive
brightness without sync. When sync pulses are
present, capacitor 309

319

base of transistor 274

clamp diodes to avoid interference with the video signal.

emitter voltage of the buffer transistors. The rest of
the video interface functions the same as the DC

The video amplifier drive circuit is built on a
ceramic substrate which is a good heat sink.
The printed resistors and conductors are small
and have precise geometries which output a
faithful reproduction of the input signal with
good high frequency response and low overshoot.
The NE592 is a 120MHz emitter coupled
differential amplifier which is connected to a
push pull output stage. This output stage
has a low bias current of 3mA and a
bandwidth of 25MHz. Although at 25MHz,
the output stage current increases to 15mA.
VIDEO AMPLIFIER CIRCUIT DESCRIPTION
The video amplifier's output voltage, with
no input signal, is the black level which is the
picture tube cut off voltage. This voltage is set,
for each of the three video amplifiers, by the
auto bias circuit via the bias control line. This
black level voltage has a range of 80V to 110V.
The voltage swing at the output is 60 volts
for a 10 mA current signal from the C5346.
For this same 10 mA current signal, the
voltage swing at the video amplifier input is
1.5 volts and the input voltage swing at the
NE592 is .80 volts. The reason for using the
voltage divider K6
K6 and K7 is that the C5346
minimum output voltage is 7.7 volts, and the
bias voltage at the NE592 input is 5.3 volts.
The input signal is buffered by a NPN
K34 for low input capacitance.

The high voltage in the CRT, through an arc, can
be conducted to any tube socket connection on the
video board. To reduce the danger of these arcs
causing component failure, a number of arc current
paths are provided. The tube socket has integral
spark gaps which conduct arc current to the tube
ground (aquadag). through dissipation resistor 882
882 .
The clamping voltage of the spark gaps to the
cathodes and G1 is about 1.5KV.
G1 is connected to a negative voltage to increase the
cutoff voltage which reduces the dot size and produces a
sharper picture. This negative voltage is generated by
rectifying the negative peaks of the filament flyback
pulse with diode 870 , filter capacitor 868
868 , and resistor
872 . Resistor 872
872 is used to adjust the negative G1

CRT AUTO BIAS AND AUTO BRIGHT CIRCUIT, FUNCTION, DESCRIPTION.
The auto bias circuit is a control system that
forms a closed loop for controlling the CRT bias
voltage. It generates a set of conditions where
the current near the cutoff voltage of each gun is
measured, and then adjusts the bias voltage of
the video amplifiers, to set the correct black level
voltage for each gun. This color balance
adjustment is necessary, since each gun in the
color picture tube can have a different cutoff
voltage, which also, will change as the CRT ages.
If the picture tube gain changes, the auto
bias circuit would adjust all three guns in the
same direction to maintain constant black
level. This effect reduces the auto bias
voltage range which is needed for the cathode
differential voltage adjustment. To prevent
this occurrence a second control loop is added
to the system. This second control loop is
called the auto bright circuit and corrects for
CRT gain changes. The auto bright circuit
senses any common bias voltage change and
controls the screen grid (G2) to hold the
common bias voltage constant.

The auto bias circuit performs all of its
sensing and bias corrections during the
sixteenth to the twenty first horizontal cycle,
after the vertical sync pulse. Before the
sixteenth cycle, the SW in the auto bias IC is
open ( SW in "C" position).
During the 16,17, and 18 horizontal cycle,
the CRT is brought out of cutoff by the grid
pulse. The resulting beam current produces
a voltage at the beam current buffer output.
This voltage is applied to the coupling
capacitor 921 . At the other side of the
coupling capacitor is the channel input, which
is clamped to V ref. (SW in "A" position). The
voltage amplitude of the amplifier output with
the cathode current information is then stored
in the coupling capacitor 921 during this
time.
During the next three horizontal cycles (19,
20, and 21), the SW is switched to pass current
to capacitor 895 which is the bias voltage
storage capacitor. At the same time a
program pulse is applied to resistor C8
C8
which, if the bias was correct during the
previous cycle, exactly balances the voltage
stored in the coupling capacitor and no
difference is sensed at the channel input. The
channel amplifier, in this case, does not
output current and the voltage of capacitor
895 stays unchanged.
895
If the CRT cathode is too far into cutoff, less
beam current flows at the grid pulse time.
This causes the beam current buffer to output
a smaller negative pulse and less voltage is
stored in the coupling capacitor. The program
pulse amplitude (which is constant) is now
larger than the stored (beam current) voltage
and the channel amplifier will add current to
95 thus
the, bias voltage, storage capacitor 8895
correcting the low bias voltage which caused
the cathode to be too far into cutoff. After the
program pulse is over, the SW is switched to
the open position again and the next time the
bias voltage can be adjusted is during the
next vertical blank time.

CRT AUTO BIAS AND AUTO BRIGHT CIRCUIT DESCRIPTION.
The beam current feedback circuit uses a PNP video
transistor 954
954 to direct most of the beam current to the
auto bias circuit while passing the voltage waveform,
from the video amplifiers to the CRT cathodes. Diode
956 insure that no video waveform
958
and capacitor 956
distortion occurs. An additional benefit of this circuit is
that it protects the video amplifiers from the destructive
955 divide energy due
arc energy. Resistors 948 and 955
to CRT arcing, between the video amplifier transistors
954 . The
and the beam current feedback transistor 954
beam current is filtered by capacitor 941 and resistor
C10 and is buffered by an operational amplifier, which
translates the beam current into a low impedance
voltage. This voltage is applied to a coupling capacitor
921
through a 200 ohm resistor C8
C8 .
The 200 ohm and the 68.1K resistor C3 forms the
program value which sets the black level voltage via the
action of the program pulse.
Capacitor 922
922 is used to stabilize the
transconductance amplifier which is used at the channel
input of the auto bias IC 927 . The auto bias IC stores
the bias voltage of this channel in capacitor 895
895 at pin
21. This voltage is buffered by an internal amplifier,
with output at pin 20, which is connected to the Blue
video amplifier bias control input.
Resistor 908
908 , 910
910 , and 911
911 are part of the auto
bright circuit. They are used to sum the bias voltage of
each of the three channels via a voltage node at the auto
bright amplifier, 920 pin 9. The resulting output
voltage then controls the screen grid via transistor 850 .
Resistor 881 protects the CRT grid from excessive
current during arcing. Capacitor 878 supplies a low
AC impedance to GND to insure that the CRT gain is
constant during each horizontal line. Resistor 858
858 and
914 defines the current gain of, and stabilizes, the auto
bright control loop.
909 eliminates crossover distortion from
Load resistor 909
920 . Resistor 852 and 856
the OP Amp. 920
856 protects the
transistor and OP Amp. from damage due to CRT
arcing.
PNP transistor 928
928 is used as a voltage translator to
direct the grid pulse from the auto bias IC to G1. The
voltage on G1 is normally -15 to -27 volts depending on
which CRT is used. When the grid pulse at pin 11 is
933 is conducted to
low, the current from resistor 933
resistor 874 and produces a 10 volt pulse on the minus
G1 line. Capacitor 871
871 and resistors 855 & 873
protect transistor 928 from CRT arcing.
The auto bias IC (CA3224E) is designed for a supply
voltage of +10V and since the video amplifier requires
+12V, three diodes 903 , 905 , and 906 are used to
C7 form a voltage
supply this IC. Resistors C4 and C7
divider which supplies the, auto bright, bias voltage to
920 . The green and blue channel circuits
the LM324 920
are identical to the red channel and are controlled by
the timing logic in the same way.
Refer to the waveforms at the bottom left of page 34
for the timing relationship. The vertical retrace boost
pulse, from the LA7838, (15KHz models) or the delayed
vertical sync pulse from the sync delay circuit (25 &
31KHz models) starts the 21 count auto bias state
counter. This pulse is applied to the auto bias IC
through resistor 891 . The negative going flyback
pulse which is used to heat the filament also supplies
the horizontal sync to the auto bias IC via diode 884
and resistor 888 . The grid pulse becomes active
between the 15 and 18 horizontal cycle and the program
pulse is active between the 18 and 21 horizontal cycle.
These two pulses in conjunction with the internal
control of the transconductance amplifier output switch
are what establish the timing for the measurement and
setting of the video bias.
CRT AUTO BIAS, VERTICAL SYNC CIRCUIT DESCRIPTION.
The auto bias vertical sync comes from from a buffer circuit
for 15KHz operation. For 31KHz operation this signal is
generated by a delay counter. For both cases, the vertical
boost pulse is "and" connected with the Vertical Osc. O/S to
provide flicker free operation and laser beam protection. In
the case of vertical deflection failure, the loss of the boost signal
causes the auto bias vertical sync to stop, which stops the auto
bias function, and blanks the screen via the vertical blanking
circuit, thus providing for laser beam protection.

The vertical oscillator one shot (LA7851 pin 16)
supplies the start timing for the auto bias vertical
sync. This signal is conducted to the emitter of
379
379 by jumper 089
389 . The base of 379 is connected
383
to the retrace boost pulse by resistor divider 383
and 384 . Combining these signals in this way
produces a collector waveform which has the vertical
oscillator one shot timing and is dependent on the
retrace boost pulse.
For the 15KHz case, transistor 100
100 inverts the
vertical oscillator one shot signal to produce the
CRT auto bias vertical sync signal. Resistor 099
is the pullup and resistor 006 reduces the
chance of arc damage to the transistor.
For the 31KHz case, the vertical oscillator one
shot signal is directed to the clear of the 7 bit
counter 100 . This O/S time out must occur after
the autobias delay time out and come before the
bias active pulse from the CA3224E. When the
clear is low, the counter counts horizontal pulses,
by the clock connected voltage divider 099 and
201
201 . When the counter outputs ones at each diode
connected output, further counts are inhibited by
381 . This diode "or" signal
diode 006
006 and pullup 381
is also used for the CRT auto bias vertical sync.
The delay is set to locate the grid pulse generated
3 faint lines at the top of the screen with full
vertical deflection. Capacitor 091 produces a
delay to avoid a race condition between the counter
clock and the auto bias horizontal sync.

Blanking in this monitor is accomplished by
reducing the video gain to zero during the
vertical and horizontal blank time. During
video time, the gain is set by the master gain
control which is located on the remote control
PCB. If the overall beam current exceeds
.75mA or 1.5mA (depending on model) for
more then ten frames, the beam current
limiter circuit will reduce the video gain to
protect the FBT. A high temperature sensor,
close to the FBT, will also reduce the beam
current if the high temperature limit (70°C) is
exceeded.
The fault circuit senses the temperature
or beam current line and will turn off the
monitor if either of these signals exceeds the
beam current shut off value. If an abnormal
condition exists in the monitor or the cooling
system of the enclosure fails, the high
temperature sensor will activate the fault
circuit at 80°C. The fault circuit is also
turned on when the beam current becomes
large enough to damage the FBT. This
condition will happen if the video bias supply
(V+ –9V) on the video board fails. An OP
Amp. is used to sense the fault condition and
a transistor is used to transmit the fault
signal down to the power supply.
The video P-P voltage amplitude at the
cathodes, is the video input signal
amplitude times the master gain control
setting times the video amplifier gain.
The gain select resistors set the maximum
video gain via the master gain line. For a
greater range of brightness, (highlighting)
the video system is allowed to supply high
peak video currents which could damage
the FBT if sustained. The beam current
limiter circuit insures that the long term
maximum beam current is not exceeded.
Horizontal blanking is achieved by
amplifying the flyback pulse (FBP) with
072 . Vertical blanking starts
transistor 072
as soon as the LA7851 starts the vertical
retrace sequence and is terminated by the
auto bias, bias active signal. A comparator
is used to sense the vertical bias O/S, at pin
16 of the LA7851, which goes low when
207
vertical retrace starts. Capacitor 207
holds the vertical blanking active, between
the vertical bias O/S pulse, and the bias
active pulse. When the bias active line
207 is reset and
goes high, the capacitor 207
vertical blanking ends, after the bias active
line returns to it's high impedance state.
75
BLANKING, MASTER GAIN, AND FAULT CIRCUIT DESCRIPTION.
The master gain control 485 is connected
to the video gain line through a 1K resistor
062 . The voltage range of the video gain
062
064 , 076
076
line is programmable via resistors 064
and solder bridges at S , T , & U
U.
The solder bridges may connect resistors
244 , 245
244
245 , 258 , and 260 to the video gain
line. This arrangement permits a variety of
input signals and picture tubes to be used
with the same monitor PCB.
Horizontal blanking ( H B ) is added
to the gain line by transistors 072 . This
transistor pulls down on the gain line when
the flyback pulse is high. Capacitor 081
081 is
080 and resistor 093
093 such
charged by diode 080
that, as soon as the flyback pulse starts going
positive the NPN transistor 072 turns on
and horizontal blanking starts. The time
constant of capacitor 081 and resistors 078
and 093 is chosen such that the capacitor
will lead the FBP on the downward slope and
turn the horizontal blanking transistor off
just at the end of the FBP. This advanced
timing compensates for the turn off delay of
transistor 072
072 .
Vertical blank time is started when a low
going pulse from the LA7851 pin 16 causes
the output, pin 1, of the dual comparator
210 to go low. Capacitor 207 is discharged
210
208 at this time. After the
through resistor 208
end of the LA7851 pulse, the capacitor
207 holds the output, pin 7 of the
comparator, low until the bias active pulse
recharges the capacitor 207
207 through diode
253
253 . During the high time of the bias
active pulse, the comparator output pin 7 is
still low, because of the voltage drop across
253 . The end of vertical blank
the diode 253
time occurs when the bias active line
returns to it's high impedance state. The
capacitor 207
207 holds the charge from the
bias active pulse until the next vertical
blank time. The advantage of this type of
vertical blanking circuit is that, if the CRT
auto bias IC fails to produce a bias active
pulse, the screen stays blanked. This action
protects the CRT when the vertical
deflection system fails since the output of the
LA7838 boost pulse is needed for the CRT
auto bias vertical sync (CA3224E pin 8).
76
The video gain line will source up to 32mA
during blank time, which is the reason for
buffering the vertical blank comparator with
a PNP transistor 212 .
Resistors 251 and 252 supply a voltage
that is midrange relative to the LA7851 pulse
for maximum noise immunity.
248 and 250 also supply another
Resistors 248
midrange voltage for the bias active pulse
and the, vertical blanking, hold capacitor
207 to work against. Resistors 211
211 and
368
368 are used as jumpers.
The beam current limiter circuit uses the
base to emitter voltage of a darlington
transistor 036 to set the maximum beam
current. To sense the beam current,
capacitor 010
010 integrates the current pulses
produced by rectifying the high voltage
flyback pulses. The beam current is
converted to a voltage across resistor 009 .
This voltage is applied to a long time
011 and
constant RC circuit, resistor 011
014 , before it is sensed by the
capacitor 014
darlington transistor. The sharpness of the
012 ,
limiting response is set by resistors 012
065 and 066
066 . Transistor 071 then,
065
reduces the video gain by pulling down on
the master gain line upon excessive beam
current. The beam current is also reduced if
the FBT temperature sensor exceeds 74°C.
Resistor 020 sets the temperature at which
this circuit becomes active. The resistance
of thermistor 180 decreases with increasing
temperature until the voltage at the cathode
of diode 018
018 is low enough to turn on
transistor 036
036 which turns on transistor
071
071 and darkens the screen.
The fault circuit senses the temperature
or beam current line with a, comparator
connected, OP Amp. 033
033 at pin 2 (– input).
The + input of the OP Amp. is biased to
3 volts by a voltage divider, resistors 034
034
037
and 037 . The output of the, OP Amp. is
connected to a low pass filter, resistor 017
035 to insure that the fault
and capacitor 035
circuit does not become active on power up.
008 conducts the fault signal to
Transistor 008
the over voltage protect input of the power
supply IC. Resistor 005
005 protects the voltage
translator transistor 008
008 and the power
supply controller IC.

Composite sync or separate vertical and horizontal sync
are buffered by two comparators in the sync interface
circuit. A vertical sync synchronization circuit is used to
insure a stable raster and functions as a sync separator.
The synchronization circuit is bypassed, for interlaced
vertical sync, because this circuit rejects the half
horizontal line time variation used to generate the
interlaced vertical raster.

The sync interface comparators are biased to .15 volts,
by resistors 323 & 327 , to permit receiving low level
sync signals such as RS170. For low level composite
sync, the vertical and horizontal lines are tied together
and jumper 328
328 is left off. For normal amplitude sync,
(greater than 2.3 volts) resistors 325 & 326
326 form an
attenuator to protect the sync interface comparators and
normalize the sync amplitude. This combination also
reduces noise sensitivity since the sync voltage amplitude
is low at the comparator input which slows the
comparator response and acts as a low pass filter.
For the interlaced sync case, the pullup resistor 321 is
left off and the voltage divider resistors 246
246 and 257 act
as the pullup. Also the vertical sync synchronization
comparators are disabled by changing the input resistors
to bias the comparators in the high output state and
366 is left off. Capacitor 254
254 acts as a sync
resistor 366
separator for composite interlaced sync. Capacitor 259
and jumper 364
364 are used to couple the composite sync to
the LA7851 vertical sync input pin 19.
The vertical sync synchronization window comparator
generates a pulse, a little after the midpoint of each
horizontal cycle. This pulse is shorted to GND by
transistors 255
255 except when vertical sync is active. The
two transistor circuit permits using either positive or
negative pulses for vertical sync.

comparator pulse to act as the sync pulse.
A sawtooth waveform is produced on integrating

358 by applying the flyback pulse to resistors
360 & 357
357 . This sawtooth waveform is connected to two
353 ,
comparators which are biased by resistors 353
356 , 354 , & 360
360 such that both comparator outputs are
high between 1.8 volts to 2.3 volts. This circuit would
produce a pulse on both the positive and negative slope
parts of the sawtooth waveform. Resistor 357 eliminates
the output pulse on the negative slope by introducing part
of the flyback pulse to pin 8 which keeps the comparator
from going high at this time. Resistors 364
364 & 366
366 act as
a pullup for the window comparator and apply a 6 volt bias
to the vertical sync input, LA7851 pin 19. At 6 volts, the
vertical sync input is inactive. It becomes active only
when the window comparator output and the ± sync
transistors are all high.

The vertical oscillator in the LA7851
supplies timing to the vertical deflection IC
to maintain a raster with no sync present.
Vertical sync supplies the timing when sync
is present.
The one shot in the LA7838 clamps the
ramp forming capacitor 401 to 5V during the
first half of vertical retrace.
The ramp forming capacitor is supplied with
current by a current source at pin 6. The
current source has a fixed 6 volt input voltage
at pin 4. A linear ramp is generated if a fixed
resistor is connected from pin 4 to GND.
Feedback from the yoke current, via resistor
403 , is used to modify the linear ramp which
helps correct for nonlinearity introduced by
the voltage feedback circuit connected to
pin 7. The vertical size control is connected to
the current source input since adjusting the
slope of the ramp adjusts the vertical size.
This ramp with the clamp, as the discharge,
produces a sawtooth waveform which is
connected to the + input of the vertical control
differential amplifier at pin 6.
The combination, voltage and current,
feedback circuit senses the parabolic
waveform on the yoke coupling capacitor
449 and is connected to the yoke current
sense resistor 385
193 . This circuit is then
connected to the other input of the differential
amplifier at pin 7. A capacitor
391
391 smoothes the parabolic waveform and a
voltage divider is used to set the output bias
voltage. The time constant, of the capacitor
391
391 and resistor 392
392 , is set to produce good
vertical linearity. An additional linearity
correction circuit is added to fine tune vertical
linearity. This circuit can be set to add or
subtract deflection from the upper and lower
portions of the raster.
The differential amplifier controls the
power output stage which drives the vertical
deflection yoke. The retrace booster is
turned on when the ramp voltage is set to
the clamp voltage and is reset when the yoke
feedback voltage balances the ramp voltage.

horizontally, with respect to the raster.
3. To operate stability through periods of
missing horizontal sync pulses.
4. To keep the picture from drifting within
the operating temperature range.
All of these functions except for the picture
position adjustment are accomplished by the
phase locked loop. Delaying the horizontal
sync with an adjustable timer produces the
picture position adjustment.
The horizontal sync input circuit (pin 1) will
trigger the picture position one-shot (O/S) on
either the rising edge, or the falling edge, of the
horizontal sync pulse. To accomplish the edge
triggering, the sync pulse is differentiated by
capacitor 352
352 into two short pulses, one for the
rising edge and one for the falling edge of the
sync pulse. Which edge is the trigger depends
on the bias voltage at pin 1. For positive edge

The picture position O/S clamps timing capacitor
to 8.2 volts until horizontal sync triggers this O/S.
The voltage on the timing capacitor drops at a rate set
by the horizontal position control 484
484 and resistor
II44 . When the voltage, at pin 2, drops below 4 volts
the delayed sync O/S is triggered and capacitor 351

functions the same as the picture position O/S with the
exception that it is not adjustable.

The flyback pulse, connected to pin 4 through

produced by a current to capacitor 348 , drops to 3
volts, the sawtooth generator switches back to the
positive slope part of the wave till the next FBP.

If the delayed sync pulse occurs when the
sawtooth is at a low voltage part of its cycle,
capacitor 346 discharges and the oscillator
frequency lowers. If the delayed sync pulse occurs
at the top part of the sawtooth wave no current

permits small rapid changes of the control voltage at
pin 7 for locking of the oscillator to horizontal sync.
The horizontal oscillator capacitor 345

charges to its upper voltage limit through resistors
I10 , I16 , I15 , II14
14 , and 336
336 . This capacitor is
then discharged to the lower voltage limit through the
action of discharge pin 9 and resistor I I9
9 . The free
running frequency (Hfo) may be adjusted by making
solder connections on the I PRA. (see page 65 for the I
PRA layout). In some cases where there are many
missing horizontal sync pulses, it is necessary to
adjust the Hfo closer than ±200 Hz. For fine tuning
the Hfo, resistor 336 is replaced with a pot.
The horizontal phase locked loop then consists
of an oscillator which sets the flyback timing.
The flyback pulse is then compared to the incoming
sync pulse and the difference voltage holds the
oscillator at the sync frequency.

The horizontal output transistor 433

The flyback transformer's main function is to
supply EHT to the CRT. It also supplies the
focus and screen grid voltages which are taps on
the EHT supply. There are three low voltage
secondaries. One supplies the filament

and supplies sync for the horizontal PLL, the

HORIZONTAL RASTER WIDTH CONTROL CIRCUIT DESCRIPTION.
The purpose of the horizontal width control is to:
1. Provide a convenient means for adjusting
the horizontal raster size.
2. Correct pincushion distortion in the vertical axis.
3. Correct horizontal raster distortion caused by
periods of high beam current.
The horizontal width control circuit is comprised of
two main parts; The control circuit and the diode
modulator (DM). The control circuit combines four
signals in the monitor to produce the width control
circuit. These signals are:
1.
2.
3.
4.
Horizontal size - - - - - - H. Size Pot.
Vertical current (Iv) - - V. current feedback resistor
Vertical parabolic + Iv Vertical yoke return.
Beam current - - - - - - - EHT return on the FBT
The diode modulator controls the horizontal yoke
current which affects the horizontal size. This is
accomplished by the diode forward current. In effect,
the diode shorts out the horizontal width coil to the
extent of the diode forward current during the previous
horizontal trace time. The current used to control the
diode forward current comes from the diode modulator
and is controlled by the control circuit and the
switching mode driver.
The horizontal size voltage from the remote control
490
is applied directly to the current node
PCB 490
(LM392 Pin 5) of the control amplifier by resistor 043
043 .
For pincushion correction, two separate signals are
used. The inverted vertical current waveform
(TP 34) and the yoke return waveform (TP 33). The
yoke return waveform includes a parabolic and linear
component. The inverse of the linear component is
added to the yoke return waveform to correct the
pincushion. The vertical current waveform (Iv) is
029 and 051 .
inverted by an Op Amp and resistors 029
Resistor 031 level shifts the inverted Iv to + 6V.
The (vertical parabolic + Iv) is AC coupled by capacitor
082
082 and resistor 038
038 and 040
040 . It is then
amplified by an Op Amp connected as a voltage
038 protects the Op Amp against
follower. Resistor 038
050
arc related voltage spikes. Load resistors 050
and
053
053 prevent cross over distortion of the Op Amps by
using only the current source transistors.
The inverted Iv and (parabolic voltage +Iv) are added
to the current node of the control amplifier by resistors
041
041 , 042 , 030
030 , & 052
052 which then makes up the
pincushion correction signal.
The beam current from the FBT is converted to a
009 and is filtered by capacitor
voltage by resistors 009
010
010 . Resistor 097
097 then connects the signal to the
current node of the control amplifier, which
accomplishes the blooming correction function.
These circuits are designed around a virtual ground,
the +6 volt line. This line is generated by buffering a
voltage divider 022 and 023 with an OP Amp.
Resistor 021 and capacitor 026 form the output filter.
84
The power output stage of the horizontal width
control circuit is a high efficiency switching mode
057
driver. The FBT pulse is integrated by capacitor 057
through resistor 095 and level shifted by resistor 058
058
to produce a saw tooth waveform. See waveform block
TP 39. By connecting one input of the comparator, in
049 , to this sawtooth signal and the other
the LM392 049
input to the control amplifier a switched signal with a
duty cycle dependent on the control voltage is
056 form
055 and 056
produced at the output. Resistors 055
a voltage divider which limits the control voltage
amplitude to be within the sawtooth waveform.
Resistor 060 acts as a pullup for the comparator

output. Resistor 461
461 couples the power MOSFET 460
to the comparator. Capacitor 463
463 and resistor 464
464
are connected as a snubber circuit to reduces noise due
to rapid drain transitions.

(Diode Modulator)
The dual focus CRTs require a waveform on the #2 focus grid. This voltage waveform is dependent on the
position of the beam on the CRT. The lowest voltage part of the waveform is in the center of the screen and the
highest voltage part of the waveform is at the corners of the screen.
The dynamic focus circuit produces a composite waveform which consists of the horizontal parabolic waveform
and the vertical parabolic waveform. This composite waveform is applied to the dynamic focus input, of the
flyback transformer, and produces a sharp picture on the dual focus picture tubes. Typically dual focus picture
tubes produces a sharper picture than the single focus picture tubes.
Dynamic Focus Circuit Operation: The vertical component of the dynamic focus circuit is derived by
amplifying the voltage waveform across the vertical yoke coupling capacitor. The horizontal component of the
dynamic to focus circuit is produced by applying the voltage waveform across the horizontal yoke coupling
capacitor to the dynamic focus transformer primary. This transformer steps up the horizontal parabolic
voltage from about 33V to about 300V to produce the horizontal component of the dynamic focus circuit.

Vertical Booster Amplifier Circuit, Circuit And Function Description.
Monitors with vertical deflection current which exceeds
2.2 Ap-p cannot be driven directly by the LA7838 vertical
deflection IC. The vertical booster amplifier circuit
reduces the output current of the LA7838 by amplifying
the vertical deflection current. The LA7838 is mounted
on the vertical booster amplifier circuit board to allow the
boosters circuit to be inserted at the output of the LA7838.

The switching regulator includes the
power FET 136 which passes current from
V- to GND through the inductor 166 .
During the time the FET is on, the current
in the inductor is increasing and the
inductor is storing energy.

137
When the FET is turned off, the stored
energy in the inductor continues supplying
current to GND. But in this case, the
current path is from V+ to GND, instead of
V-to GND. During this part of the cycle,
the current in the inductor is decreasing.
Under normal conditions, the current will decrease to zero and the voltage will ring.

Flyback pulse
As can be seen from the waveforms, the
largest number of changes occur when the FET is
turned off. Also, the FET drain voltage switches
fast due to the high inductor current. To
minimize video interference from the power
supply, the power supply is synchronized to the
horizontal oscillator such that horizontal
blanking is coincident with the FET turn off time.
The C5184 115
115 is the series regulator
IC. All of the control circuits that are
built into this IC work together to produce
one output signal, which is the FET drive
signal. This signal can take on many
shapes depending on the load conditions of
the power supply. The waveforms for
normal operation are shown above.
For the shorted +127V to GND condition, which also occur right on power up,
the waveforms are:
FET Gate Drive
FET Drain Voltage
Inductor Current
The first FET pulse is a full on pulse
which causes current to flow in the inductor.
After the FET is turned off the current in
the inductor drops much more slowly than
normal since the inductor is discharging
into a much lower than normal voltage. If
the FET were turned on for full power in the
88
next cycle with current still flowing in the
flyback diode, a current spike of 6A would
occur, which is a power spike of 2,000W.
The reason for this is that the diode stores
charge when current flows which turns into
reverse current for a short time when the
voltage is reversed across the diode.
SIMPLIFIED POWER SUPPLY CIRCUIT DESCRIPTION.
The FET drive circuit avoids this problem
by sensing flyback diode conduction. If the
flyback diode conduction is sensed, the low
current start mode is selected. This mode
turns the FET on, to a current of .1A, for not
more than 4uS. If before or during the low
current FET on time, the flyback diode breaks
free, and the FET drain voltage goes down,
the flyback diode voltage comparator will
signal the regulator to permit the FET to be
turned on for a full power cycle. The cycle
after the last low power cycle in the waveform,
on the previous page, is an example of this
condition. The flyback diode voltage
comparator inputs are located at pins 12 & 13
of the C5184. The two resistor dividers ( see
next page ) J10
J10 , J11
J11 and J12 , 134
134 connect
the comparator across the flyback diode 142 .
The comparator enables the FET drive only
after a 10% voltage drop is measured across
this diode.
Another fault condition exists when the
FET exceeds 5A drain current. This
condition can occur if the oscillator frequency
is too low, the FET drain is shorted to GND or
V+, the transformer has a shorted secondary,
or the core is broken. In these cases the
voltage across the FET source resistor 137
exceeds 1.6V which is sensed by the over
current comparator at pin 11. If pin 11
exceeds 1.6V, the FET drive is set to 0V for
the rest of the cycle. In some cases, this
condition can produce an output waveform
which looks normal, but the voltage across the
load (+127V to GND) would be low or
unstable. A quick check for this condition is
to check the peak voltage across the FET
source resistor. CAUTION; Whenever
connecting a scope ground to V-, be sure that
the other scope probe or common grounded
devices are not connected to the monitor GND.
Most of the power supply fault conditions
cause the power supply to chirp because the
source of +17V for the C5184 is generated by
the power supply. A special circuit is built
into the C5184, which permits charging the
+17V line filter capacitor with only a very low
load from the C5184. This circuit turns the
rest of the C5184 on only after the voltage at
pin 15 reaches 17V. If the transformer does
not supply at least 12V to this line before the
filter capacitor discharges to 12V, the C5184
turns off. The reason for the audible chirp, is
that, the power supply is not full on for each
cycle which produces a frequency low enough
to hear. See the bottom waveform on the
previous page.
A 0-30 volt @ 1A, DC, isolated power supply
is a tool necessary for trouble shooting
CERONIX monitors. When trouble shooting
the power supply, it can be connected to Vand the +17V line to keep the power supply
running while checking the voltages and
waveforms to find the fault. Caution, do not
exceed 20 volts on the 17 volt line. It can also
be used to supply the GND to +16V line for
checking the horizontal circuit. If the
horizontal circuit does not work, the power
supply will chirp. Without the horizontal
circuit working, there is not enough load on
the power supply for transformer action to
keep the regulator IC +17V line up to the
minimum of +12V. A quick check for this
condition is to clip a 2-4K @ 10W power
resistor from GND to V+. If the chirping
stops, the horizontal is probably not working.
The heart of the power supply is the
oscillator which supplies the basic timing.
The FET drive is always low during the
negative slope of the oscillator or, when
synchronized, after the start of the sync pulse.
The low to high transition of the FET drive,
pin 10, is determined by the voltage at the
output of the error amplifier. If V+ goes up in
voltage, the error amplifier voltage goes up,
which then intersects the oscillator waveform
at a higher voltage and causes the FET on
time to start later and be shorter. This
negative feedback accomplishes the control
loop of the power supply.
The regulator IC has a built in reference
voltage which is used by the error amplifier
to set and hold the V+ constant. Solder
connections on the J PRA are used to adjust
V+ in steps of ±1.5V.
The over voltage protect ( OVP ) circuit,
when activated, turns off the regulator IC
until power is disconnected. This circuit is
connected to the rectified flyback pulse, which
outputs a voltage that is proportional to the
EHT. The circuit's main purpose is to protect
the user against excessive x-ray which is
caused by excessive EHT. The OVP circuit is
also activated if the monitor temperature goes
too high or if too much beam current is
demanded from the FBT. The purpose of the
last two functions is to protect the FBT and
the CRT from component failure on the main
or video boards.

compared to a reference voltage by the error
amplifier. If the +127V line goes up the output
of the error amplifier voltage goes up.
The pulse width modulation, which controls the
+ 127V line voltage, is accomplished by turning
the FET drive on at some particular voltage
along the rising slope of the oscillator waveform.
This particular voltage is the error amplifier
output voltage. See waveforms above.
The FET drive is always off during the
negative slope of the oscillator, or just after the
sync pulse. Since the FET drive pulse is started
by the error amplifier voltage and terminated by
the end of the oscillator cycle, a control system
via pulse width modulation has been established.
The oscillator waveform is produced by charging
capacitor 102 with a constant current set by
J7 to a voltage of 5V and then
resistor J7
discharging the capacitor with double the
charging current to 2.5V. Adding the flyback
pulse, via capacitor 123 to this waveform
synchronizes the oscillator, since the oscillator
frequency is set below the horizontal frequency.
J2 , J4
J4 and capacitor 108

Resistors J2
error amplifier's AC gain, to hold the control loop
stable. Capacitor 107 holds the error amplifier
stable. Capacitor 110 reduces power supply
noise, but, if too large, will cause the power
supply to be unstable. The 127V line is adjusted
by making solder connections on the J PRA (refer
to page 65 for the layout). Solder connections JC
and JD are used to raise the 127V line up to 4.5
volts in steps of 1.5 volts. Connections JA and JB
JB
lower the 127V line as much as 4.5V.
The FET 136 works together with the
transformer 166 to provide a low resistance
current path from V- to GND. This low
resistance coupled with no large voltage times
current products is what makes the power
supply efficient. Resistor 137 provides a
means for sensing the FET current. In the low
current mode, it is used to set the 300mA current

provide a means for checking flyback diode
142 conduction via a comparator. If the
comparator measures low flyback diode voltage
the FET is turned on to the .3A low current
mode. This mode is necessary for power up,
since initially the +127V line is 0V and no
reverse diode voltage exists. The over voltage
protect circuit, at pin 14, has a trip voltage of
8V and when it is activated, it shuts down the
power supply. The EHT is measured by
rectifying the flyback pulse, with diode 130
130 ,
from a secondary winding of the FBT.
Capacitors 125
126 , J9
J9
125 , 124
124 and resistors 126
are connected as a low pass filter to smooth out
the simulated EHT voltage which is then
applied to the C5184 at pin 14. Resistor J8
J8
protects the IC current sense input from
voltage spikes and resistor 113 protects the
PNP transistor from momentary overvoltage
damage due to line spikes. Zener diode 181
protects the horizontal and video circuits from
overvoltage due to power supply failure. If the
+127V line exceeds 160V, the zener diode 181
shorts to GND the +127V line.
At the input to the power supply is a
voltage doubler which outputs between 240 to
425VDC depending on the AC line voltage. It
has a three amp fuse 146 to protect the PCB
159 to
traces, an inrush current limiter 159
protect the rectifier diodes 148
148 & 156 .
Capacitors 150
150 and 155
155 are used to reduce
diode noise from the monitor to the AC input.
For 220VAC operation the voltage doubler is
replaced by a full wave rectifier by adding
diodes 151
151 , 154 , capacitors 152 , 153
153 and
removing the jumper at 152
144 & 163
152 .
are the raw DC filter capacitors. Resistor J6
J6
supplies the power supply start current and
resistors 143A
143A and 143B balances the series
connected filter capacitors for 220VAC
operation.
Caution! When working on a monitor with a
degaussing relay, 468
468 unplug the degaussing coil
to avoid causing the residual current relay to
close on a cold posistor. This can happen if the
24V line is energized by a external power supply.

POWER SUPPLY, TROUBLE SHOOTING TIPS.
SAFETY FIRST; Use only one hand when working on a powered up monitor to avoid electrical shock.
Always wear safety glasses.
Many of the failures that cause burnt
components and boards are eliminated by the
load sensitive switching mode power supply in
the CERONIX monitor. This feature can cause
problems with servicing the monitor if the proper
trouble shooting approach is not used. The
equipment setup, shown here, is necessary for
efficient trouble shooting of the CERONIX
monitors.
Problems that cause the power supply to chirp are:
1.
2.
3.
4.
5.
Insufficient V+ line load.
Overloaded V+, +24V, or +16V lines.
Shorted V+, +24V, or +16V lines.
Power supply component failure.
Raw DC (V+ to V-) voltage too low.
1. A quick check for the insufficient V+ load is to
connect a 2K to 4K ohm 10 watt power resistor
from GND to the V+ (cathode of diode 181 ). If the
chirping stops, proceed to check the horizontal
deflection circuit. First disconnect the board from
the AC supply. Then connect 16 volts to the 16V
169 . Also connect 24 volts
line at the cathode of 169
to the 24V line at the cathode of diode 168 and to
181 on the monitor.
V+ at the cathode of diode 181
Now the complete horizontal and vertical circuits
can be checked with the oscilloscope and DVM.
The flyback waveform will be about 170Vp-p
instead of 900Vp-p which permits checking even
the H. output transistor, collector, waveform.
2. For the overloaded supply line problems, the
monitor power supply can be made to run
continuously by connecting the external power
supply to the 17V line. To accomplish this,
connect the external supply 0V clip lead to V(resistor 137
137 lead by the power transformer) and
+20V clip lead to the monitor power supply +17V
141 ). Sometimes the
line (cathode of diode 141
monitor will operate normally in this mode, in
which case, watch for smoke and after a few
minutes of operation disconnect the power
connections and carefully feel around the
conductor side of the board for hot spots. Overload
conditions will not harm the power supply unless
there is a problem in the power supply. If the
power supply is suspect, read the POWER SUPPLY
TEST section on this page. Next check the DC
voltage of each of the power supply outputs. The
overloaded line will have a lower than normal
voltage reading. The defective component can be
located by measuring the voltage drop along the
trace of this line.
94
3. If the V+ crowbar zener 181 is shorted, a fault
exists in the power supply which permitted the V+
line to exceed +160V. First replace the zener.
Never operate the monitor without the crowbar
zener installed. Then read the POWER SUPPLY
TEST section on this page. Shorts on the V+, 24V,
and 16V lines other than the crowbar zener are not
likely to be connected to the power supply even
though the power supply chirps. By operating the
power supply with the +20V external power supply
many of these problems can be found using the
same procedure as are used in trouble shooting
monitors with linear power supplies.
4.
The power supply may chirp if:
The transformer core is broken or a
winding is shorted.
The .33 ohm current sensing
resistor value is too high.
The +17V line is open. (goes away
when external. PS is used)
5. There is a line voltage range of about 60% to
70% AC line voltage where a correctly
operating monitor will chirp.
POWER SUPPLY TEST
To verify that the power supply is working
correctly, connect the 17V line, as indicated in
section 2 on this page. Also connect the
oscilloscope GND to V- and the oscilloscope probe to
116 ). There should
the FET drive (anode of diode 116
be a waveform at this point. If there is no FET
drive waveform, check the voltages and waveforms
on the C5184 pins and compare them to the
voltages and waveforms on the schematic.
Connect the AC power cord with the AC voltage,
from the variable transformer turned down to 0
volts. TAKE CARE NOT TO TOUCH THE
OSCILLOSCOPE AND MONITOR CHASSIS
DURING THIS TEST, SINCE THE VOLTAGE
DIFFERENCE CAN BE AS HIGH AS 400 VOLTS.
Connect the DVM to GND and V+. Slowly
increase the AC line voltage and observe the power
supply response. Do not exceed +145V on V+. If
the monitor runs normally, a fault may still exist
in the power supply +17V line circuit. Note; if
the crowbar zener is shorted and the FET is
internally shorted, the C5184 IC 115 should also
be replaced.
Trouble Shooting Handbook
The information that is written in this handbook is to help repair XX93 Monitors.
Here is a guideline in which this handbook will follow:
1.
2.
Color problems.
No video with power.
3.
No V-H sync.
4.
5.
Retrace lines.
No power.
Always wear safety glasses.
Caution; Use only one hand
when working on a powered up
monitor to avoid electrical
shock.
Color Problems.
A helpful hint when working with color problems is by identifying the
color of the three grid lines at the top of the screen.
When there is a missing color and the lines are white the problem lies in the video
interface section. This means it can be found between the customers game and pin 8 of
the Video Amplifier (K-Film). If the lines are not white it would be a output problem,
which is anything after pin 8 to the picture tube.
If the problem is excessive blue, green, or red background color,
tap on related K-film to see if it is defective.
If blue is the problem, check for damaged traces around the outside of
the video board, since most of these traces go to the blue K-film.
If monitor shuts down due to excessive color, disconnect the filament for
voltage tests. (Desolder CRT socket pin 9.)
Note: All voltage measurements are: DC with -lead to GND unless other wise noted.

Filament Voltage Test.
When replacing either the flyback transformer or the video
board, the filament voltage may not be correct.
Measuring the filament voltage is not accurate using a true
RMS voltage meter, because of the high frequency components,
which make up the filament voltage. An oscilloscope, with RMS
capability, may be used to measure the filament voltage.
Although a visual check of the filament color is a indicator of the
filament voltage, it is a good practice to check the filament voltage if
there is any doubt about this important monitor parameter.
The following filament voltage test is an accurate method of
finding the true RMS voltage to the filament. This is accomplished
by comparing the light output of the filament when it is driven by
the monitor to the light output of the filament with an applied DC
voltage using a loaded photocell.

HeizfadenSpannung Test.
Wenn der EHT-Transformator oder die Videokarte geändert wird, kann
die Heizfadenspannung falsch sein.
Die Heizfadenspannung besteht aus Hochfrequenzbestandteilen. Genaues Messen
der Heizfadenspannung kann nicht mit einem Effektivwertmeßinstrument erhalten
werden. Ein Oszillograph mit Effektivwertmessen-Fähigkeit kann benutzt werden,
um die Heizfadenspannung zu messen.
Obgleich ein Sichtprüfen der Heizfadenfarbe eine Anzeige der
Heizfadenspannung ist, ist es gutes üblich, die Heizfadenspannung zu
überprüfen, wenn es irgendeinen Zweifel ¸ber diesen wichtigen
Monitorparameter gibt.
Der folgende Heizfadenspannung Test ist eine genaue Methode des
Findens der zutreffenden Effektivwertspannung zum Heizfaden. Dieses
wird vollendet, indem man die helle Ausgabe des Heizfadens vergleicht,
wenn es durch den Monitor zur hellen Ausgabe des Heizfadens mit einer
angewandten Gleichstromspannung mit einer einprogrammiert Fotozelle
angetrieben wird.

SETUP AND CONVERGENCE PROCEDURE
1. Use a knife to brake free the magnetic rings
on the yoke, which are usually locked with
red varnish. Bring the adjustment tabs on
each pair of magnetic rings in line for the
starting point.
2. Loosen the yoke clamp. Remove the yoke
wedges and the tape from the CRT.
7. Adjust the yoke position, on the CRT neck,
to the center of purity. One way to locate
this yoke position is to make a felt pen mark
on the CRT neck at the rear extreme of
purity and another mark at the front extreme
of purity. Make a third mark between the
two marks and set the yoke to this position.
Rotate the yoke to line up, the raster top line,
with the top of the picture tube. Tighten the
yoke clamp. Tilt the yoke side to side and up
and down while watching the red field to
verify that purity is good.
3. Connect a test generator to the video input.
4.
Turn the monitor on.
Switch the test
generator to red field. Adjust the horizontal
and vertical raster size, on the remote control
board, for under scan. Let the monitor run
for at least half an hour.
8. If the yoke position adjustment does not
produce good purity, adjust the purity
magnets. Tabs closest to the yoke winding.
9. Switch the generator to the red/blue grid.
Adjust the 4 pole magnets (center pair)
for convergence of the red and blue guns in
the center of the screen.
5. Check the auto bright control voltage with a

SAFETY ISOLATING TRANSFORMER

Circuit Function Description.
The basic function of the ISO XFR-75W and ISO XFR-100W is to
isolate the line power for monitors requiring an isolation transformer.
The transformer is designed to have a low leakage flux value which
allows it to be mounted close to the CRT. To accomplish the low
leakage flux, the transformer has two sets of primary and secondary
coils mounted on a modified toroid type core. The ideal transformer
would be a toroid but this type transformer is expensive because it is
difficult to wind.
A relay is used to connect the two primary coils in series or parallel to
accommodate 240VAC or 120VAC line voltages. Before power is
applied, the relay connects the transformer primary windings in series to
avoid excessive primary current for the 240VAC case. The control
circuit energizes the relay when the line voltage is 120VAC.

Circuit Description.
The fuse T506
506 protects the mains wires and the control PCB.
The power transformer has two internal 2 amp temperature sensitive fuses.
Each primary half has one, built in, series connected fuse.
507 is connected to the relay driver power supply.
A resettable fuse T507
This fuse protects the relay control circuit from square wave input which would
occur if an inverter is used as the power source. Capacitor T512
512 supplies
current from the line to capacitor T513
513 through diode T510
510 which forms the, relay
control, power supply. Diode T511
511 charges capacitor T512
512 during the negative
going part of the line wave. Transient Voltage Suppressor T516
516 regulates the
24V power supply and protects the relay coil from over heating.
T514 shorts out the 24 volt power supply when the input line
The Mos Fet 514
voltage is 240VAC.
The input line voltage, at which the Mos Fet turns on, is set by the Mos Fet turn
on voltage (about 4V), the voltage drops across resistors T509
509 , T505
505 , T504
504 , and
the zener diode T503
503 . 154VAC is the approximate line voltage at which the
relay T518
518 switches. Capacitor T508
508 and diode T502
502 keep the Mos Fet turned
on for the complete AC cycle to eliminate ripple current in the capacitor T513
513 .
504 limits the peak current to capacitor T508
508 to avoid relay switching
Resistor T504
due to line transients. The zener diode T515
515 which is connected from the Mos
Fet source to gate protects the Mos Fet gate against over voltage. Resistor
T519
519 is needed to limit the mains current when the relay arcs across both sets of
contacts. Capacitors T517
517 and T520
520 reduce the relay T518 contact noise which
may be generated when switching.

Stromkreisfunktion Beschreibung
Die grundlegende Funktion des XFR75W und des XFR100W ist, die Zeile
Energie für die benötigenden Monitoren und Lokalisierung Transformator zu
lokalisieren. Der Transformator wird entworfen, um einen niedrigen
Durchsickernflusswert zu haben, der erlaubt, daß er nah an der CRT
eingehangen wird. T vollenden den niedrigen Durchsickernfluß, hat der
Transformator zwei Sets der Primär- und Sekundärspulen, die an einem
geänderten Ringkörperartkern eingehangen werden. Der ideale
Transformator würde ein Ringkörper sein, aber diese Art des
Transformators ist kostspieliges becuase zu wickeln, das ist schwierig.
Ein Relais wird benutzt, um die zwei Primärspulen in den Serien oder in der
ähnlichkeit anzuschließen, um Spannungen der Zeile anzupassen 240VAC
oder 120VAC. Bevor Energie angewendet wird, schließt das Relais die
Transformatorprimärwicklungen in den Serien an, um übermäßigen
Primärstrom für den Fall 240VAC zu vermeiden. Der Steuerstromkreis
versorgt das Relais mit Energie, wenn die Zeile Spannung 120VAC ist.

Note: When using this isolation supply for working on monitors, it is important to have some resistance
(10MΩ or less) to ground. An insulated monitor connected to a insulated power supply may attain a high
static voltage. When this voltage discharges through the ISO XFR-75W, ISO XFR-100W control circuit,
the FET in the control circuit may be damaged.
