Sanyo Color Monitor
1 Warnings and Cautions
A. Before You Start...
You should never attempt to work on an exposed
monitor chassis if you are not familiar with servicing
procedures and precautions necessary for highvoltage equipment. Any TV monitor has three
sources of possible danger: strong electric shock
due to high voltages or unisolated AC line voltages,
X-ray radiation, and implosion. Therefore, please
read this chapter carefully.
B. Safety Measures
Develop good safety habits, so when you're
rushed with repair work, you'll still automatically
take precautions.
A good practice when working on any TV monitor
is to first ground the chassis and use only one hand
when testing circuitry. This will avoid the possibility
of carelessly putting one hand on the chassis or
ground, and the other on an electrical connection.
Doing so could cause a severe electrical shock.
Figure 1
If you service this color monitor on a test bench,
you must isolate the monitor from AC line voltage!
An isolation transformer is mandatory for your own
safety. The Sanyo monitor does not contain an isolation transformer on its chassis. It is mounted instead on the game power supply. (It may appear like
a regular power transformer, but is really also an
isolation transformer.)
C. Picture·Tube
Handling
Use extreme care when handling the picture tube,
since rough handling may cause it to implode, due
to a vacuum inside. Do not nick or scratch the glass,
or subject it to any undue pressure when removing
or installing it.
Wear safety goggles and heavy gloves for protection when handling the picture tube. Keep others
without safety goggles away. Do not lift the tube by
the neck.
Overview of Sanyo 14" Color TV Monitor
1
Sanyo Color Monitor
Discharge the high voltage in the picture tube by
shorting the anode connection to chassis groundnot the cabinet or other mounting parts. When
discharging, go from ground to anode, and use a
well-insulated piece of wire.
D. Replacing with
Proper
Components
It is important to maintain the specified values
and failure characteristics of all components in the
horizontal and high-voltage circuits, and anywhere
else in the monitor that could cause a rise in high
voltage, or in operating supply voltages.
Refer to the parts lists in the back of this manual,
and use only exact replacement parts, especially for
the picture tube, semiconductors, transformers,
coils, and fuses.
2
If you replace the picture tube with another type
not specified in the parts list, then avoid prolonged
exposure at close range to the unshielded areas of
the tube. You may endanger yourself from unnecessary exposure to X-ray radiation.
E. Final Testing Before
Reinstalling Monitor
Before installing the color monitor back in the
game, you must check the following:
1.
Inspect all harness wiring on the monitor and be
sure none of it is pinched between the chassis
and other metal parts in the monitor.
2.
Replace all protective devices such as insulating fishpaper, compartment covers and
shields.

Sanyo Color Monitor
3 Adjustable Controls
A. Brightness
Remember to observe the precautions regarding
high voltages when you make any adjustments on
this monitor!
However, if you cannot achieve the proper
brightness by using this white adjustment knob,
then you should check the master brightness level
adjustment. This potentiometer is located almost
dead center on the Main PCB, at VR201.
Note that before you adjust the brightness, the
monitor should have been turned on for at least 5
minutes. Keep the game in the attract or play mode.
Find the small white knob underneath the screen,
located at the far right on the Control Printed-Circuit
Board or PCB (see Figure 2). Turn this brightness or
screen voltage control until you achieve a pleasing
level of brightness.
To reset the brightness level, disconnect the 6-pin
video-signal connector from the monitor. Turn the
white brightness control to maximum or fully clockwise. Connect a DC voltmeter's plus lead to TP452,
and its minus lead to TP451-near the center of the
Main PCB.
Too high a brightness causes the retrace lines to
show. Too low a brightness causes the entire screen
to become dark and obscured.
Set the voltmeter to the 1.5-3 V range. Now adjust
the small VR201 potentiometer to 0.5 volts. Reconnect the 6-pin connector on the monitor.

B. Horizontal Hold
Use this adjustment if the picture drifts sideways
across the screen. Find the second potentiometer
from the right, on the Control PCB (as you face the
monitor's screen)-see Figure 2. Turn the pot until
the black lines no longer slant downwards or upwards, and you obtain a normal screen image.
C. Vertical Hold
(
convergence grid and dots. Locate the vertical
height control on the monitor's Control PCB: it is
the knob on the far left underneath the screen. Turn
this control until the top and bottom grid lines run
along the edges of the screen. The lines should not
disappear off the edges, which would indicate overscanning.
E. Horizontal Width
Before using this control, be sure the monitor has
been turned on for 5 minutes or more. If the screen
image is too wide or narrow, you should use this
control to adjust it for proper width.
Use this adjustment if the picture drifts straight
up or down on the screen. The vertical hold control
is the second potentiometer from the left, on the
Control PCB (as you face the monitor's screen)see Figure 2.
Set the game for the diagnostic that displays the
convergence grid and dots. Locate the horizontal
width control on the monitor's Main PCB: it is the
coil at the center of this board, directly underneath
the yoke. Be sure to use only a non-metal Allen
wrench (commonly called a "tweaking" tool) for this
adjustment! Turn this control until the right and left
grid lines run along the edges of the screen. The
lines should not disappear off the edges, which
would indicate overscanning.
Turn this control in either direction until the picture no longer drifts straight up or down on the
screen.
D. Vertical Height
If the screen image is not large enough or too
large vertically, then you can adjust it very easily
with this control. Using this control will stretch or
compress the image vertically. The vertical height
control affects the spacing between the raster lines
equally.
Set the game for the diagnostic that displays the
F. Focus
This control simply changes the sharpness of the
screen image. The white focus adjustment knob is
located on the plastic bracket above the flyback
transformer. Turn this control until you get the optimum screen sharpness possible.

4 Supply Voltages
To test for proper + 105V supply, locate the test
point TP91 at the front end of the very large 20-watt
resistor R609. This resistor is in the center rear area
of the Main PCB. Connect a voltmeter at this point
and to ground.
Adjust the brightness control on the Neck PCB to
maximum. Use the nearby potentiometer (VR601) on
the monitor's Main PCB that is labeled "B + ADJUSTMENT" in Figure 2. Turn this pot until the
meter reads + 105V. Then return the brightness control to normal.
5 Signal Test Points
A. RGB Signals
The blue, red, and green signals can be tested at
the points labeled ED, EE, and EA, respectively.
These are located on the back of the Neck PCB.
6
B. Horizontal and
Vertical Sync
This synchronization signal can be tested at pin 5
of the 6-pin video signal connector. When using a
test prod, do not jam it into the connector pin. Otherwise you will stretch the pin, and it could later fall
out of the connector housing.

8 Adjustments
A. Purity
Adjustments
1. Preliminary
First remove the monitor from the game, but leave
the connectors still attached. The purity and convergence magnets can be moved without loosening
the rear Phillips screw. If you will also be converging
the outer area of the picture (see Section 2 on the
next page), you should loosen both the deflection
yoke and magnet mounting screws at this time.
Turn the picture tube so it faces north or south.
Then degauss the picture tube with a hand-held
degaussing coil. If the magnets have been secured
with a white glue, you will find that its hold can be
easily broken when you move the magnets.
2. Red Purity Adjustment
Refer to Figure 3 and turn off the green and blue
guns with the G and B bias or cutoff controls, located on the neck board. (Leave the red gun on.) Display any self-test pattern on the screen that shows
solid white. Keep this display throughput the purity
adjustments.
Rotate and spread the tabs of the purity magnets
(the pair farthest towards the front) until you center
the screen image vertically and horizontally. You
should also obtain a pure red overall.
3. Green Purity Adjustment
Turn off the red and blue guns by using the controls on the neck board; leave the green gun on.
Readjust the purity magnets if necessary for a uniformly green screen.
5. Final Check
As a final check for total color purity, turn on all
guns again. Leave the all-white self-test pattern on
the screen. The screen should be pure, clean
white-not tinted with other hues.
Finally, reinstall the monitor in the game.
B. Convergence
Adjustments
1. Static Convergence (Center Area)
First remove the monitor from the game, but leave
the connectors still attached.
If you will also be converging the outer area of the
picture (see Section 2 that follows), you should
loosen both the deflection yoke and magnet mounting screws at this time.
Display the diagnostics pattern that shows black
background with white lines and dots. Keep this
display throughout all convergence adjustments.
Refer to Figure 3 and turn off the green gun with
the G bias or cutoff control, located on the neck
board. (Leave the red and blue guns on.)
Adjust the angle of the 4-pole or center pair of
magnets, and superimpose the red and blue vertical
lines in the center area of the screen.
Keeping their angles the same, rotate both tabs of
the 4-pole magnets to superimpose the red and blue
horizontal lines in the center area of the screen.
4. Blue Purity Adjustment
Turn on the green gun again. Adjust the angle of
the 6-pole or rear pair of magnets, and superimpose
the green vertical lines on the red/blue ones, in the
center area of the screen.
Turn off the red and blue guns by using the controls on the neck board; leave the blue gun on.
Repeat the purity adjustment for a uniformly blue
screen.
Finally, keeping their angles the same, rotate both
tabs of the 6-pole magnets to superimpose the
green horizontal lines on the red/blue ones.

Sanyo Color Monitor
If you do not need to converge the outer screen
areas, you are done with the convergence procedure. (Otherwise, immediately proceed with Section 2 below.)
Slide the yoke slightly away from the picture tube.
Up/down movement of the yoke causes the outer
edges of the screen image to swivel clockwise or
counterclockwise. Side-to-side movement causes
the lines and dots at the outer screen edges to expand and contract.
2. Dynamic Convergence (Outer
Area)
Move the yoke in the up/down and side-to-side
directions until the outer lines and dots on the
screen are pure white.
Be sure to keep the same convergence pattern on
the screen-white lines and dots with black
background. Using a razor blade or thin knife,
carefully loosen the glue holding the three rubber
wedges and remove them. Be sure both the magnet
and deflection yoke mounting screws are loosened.
Then secure the deflection yoke by putting the
wedges back in between the picture tube and the
yoke's white collar. Secure the wedges with glue.
Tighten the screws that secure the deflection yoke
clamp and the magnets.
9 Schematic and Illustrated
Parts Lists
The purpose of this chapter is to provide you with
the necessary information for ordering replacement
parts for your Sanyo 14" color monitor. Please note
that, for simplicity, common hardware and certain
other parts have been deleted from this parts list.
This includes screws, nuts, washers, certain connectors and tie wraps, in addition to metal parts,
such as heat sinks, shields and supports.
When ordering parts from your distributor, give
the part number, part name and serial number of
your game. This will help to avoid confusion and
mistakes in your order. We hope the results will be
less downtime and more profit from your game.
