Chapter One About Maintenance
1.1 Safety precautions
1.1.1 Power supply
When maintenance personnel are repairing DVD players, he should pay special attention to
the
power board with 220V AC and 330V DC which will cause hurt and damage to persons!
1.1.2 Precautions for antistatic
Movement and friction will both bring static electricity which causes serious damages to integrated
IC. Though static charge is little, when a limited quantity of electric charge is added to largescaleintegrated IC, as the capacitance is very small in the meantime, now the integrated IC is very much
easy to be struck through by static electricity or the performance will decrease. Thus static electricity
prevention is of extraordinary importance. The following are several measures to prevent static
electricity:
1. Use a piece of electric conduction metal with the length of about 2 metres to insert into the earth,
and Fetch the lead wire from the top of the surplus metal and connect to the required static electricity
device. The length and depth of the metal embedded under the earth should be determined according to
the wettability of the local soil. For humid places, it may be shorter, and longer and deeper for dry places.
If possible, it can be distributed and layed in terms of “#” shape.
2. On operating table-board, the antistatic table cushion should be covered and grounded.
3. All devices and equipments should be placed on the antistatic table cushion and grounded.
4. Maintenance personnel should wear antistatic wrist ring which should be grounded.
5. Places around the operating position should also be covered with electric conduction cushion or
Painted with antistatic paint.
1.1.3 Precautions for laser head
1. Do not stare at laser head directly, for laser emission will occur when laser head is working, which
will Hurt your eyes!
2. Do not use wiping water or alcohol to clean laser head, and you may use cotton swab.
-1-
1.1.4 About placement position
1. Never place DVD player in positions with high temperature and humidity.
2. Avoid placing near high magnetic fields, such as loudspeaker or magnet.
3. Positions for placement should be stable and secure.
1.2 Maintenance method
1.2.1 Visualized method
Directly view whether abnormalities of collision, lack of element, joint welding, shedding welding,
rosin joint, copper foil turning up, lead wire disconnection and elements burning up among pins of
elements appear. Check power supply of the machine and then use hands to touch the casing of part of
elements and check whether they are hot to judge the trouble spot. You should pay more attention when
using this method to check in high voltage parts.
1.2.2 Electric resistance method
Set the multimeter in resistance position and test whether the numerical value of resistance of each
point in the circuit has difference from the normal value to judge the trouble spot. But in the circuit the
tested numerical value of resistance is not accurate, and the tested numerical value of integrated IC's
pins can only be used for reference, so the elements should be broken down for test.
1.2.3 Voltage method
Voltage method is relatively convenient, quick and accurate. Set the multimeter in voltage position
and test power supply voltage of the player and voltage of a certain point to judge the trouble spot
according to the tested voltage variation.
1.2.4 Current method
Set the multimeter in current position and test current of the player of a certain point to judge the
trouble spot. But when testing in current method, the multimeter should be series connected in the
circuit, which makes this method too trivial and troublesome, so it is less frequently used in reality.
1.2.5 Cutting method
Cutting method should be combined with electric resistance method and voltage method to use.
This method is mainly used in phenomena of short circuit and current leakage of the circuit. When
cutting the input terminal voltage of a certain level, if voltage of the player rises again, it means that the
trouble lies in this level.
-2-
1.2.6 Element substitution method
When some elements cannot be judged good or bad, substitution method may de adopted directly.
1.2.7 Comparison method
A same good PC board is usually used to test the correct voltage and waveform. Compared these
data with those tested through fault PC board, the cause of troubles may be found.
Through the above maintenance method, theoretical knowledge and maintenance experience, all
difficulties and troubles will be readily solved.

2. Working principle: when reading CD disc, the loader outputs a high level (3.3v) to IOA; when
reading DVD disc, the loader outputs a low level (0V) to IOA.
When reading CD disc, IOA is high level; V304 and V305 are on; V305 collector electrode is low
level;V303 drain electrode is equal to hang in the air (laser receiver pipe inside loader selects CD
channel). When reading DVD disc, IOA is low level; V304 and V305 cut off; V303 is on; V304 drain
electrode is equal to hang in the air (laser receiver pipe inside loader selects CD channel).
Note: V303 and V304 are MOS pipe.

2. Working principle: Pin 20 of MT1389 is VCD laser power strong/weak signal input checking pin;
pin 21 is DVD laser power strong/weak signal input checking pin; 23 pin is VCD laser power drive control
output pin and pin 22 is DVD laser power drive control output pin.
When reading VCD disc, if pin 20 of U201 (MT1389) has detected that the laser output power it too
strong, after being processed by U201 (MT1389) internal circuit, pin 23 output voltage increases and the
on-state degree of V302 decreases to make the voltage supplied for pick-up decrease and the light
emitting of laser head become weak. If pin 20 has detected that the laser output power is too low, pin 23
output voltage decreases; on-state degree of V302 increases and the light emitting of laser head
become strong to reach the purpose of automatically adjusting laser output power.
When reading DVD disc, pin 21 is signal input checking pin and pin 22 is drive control output pin.
The working principle is the same with that when playing VCD disc.

Figure 3.2.4.1 Reset circuit schematic diagram
2. Working principle: The two ends voltage of capacitor T217 cannot change suddenly, anode of the
capacitor begins charging from 0V and now triode Q204 is on. Pin 5 of phase inverterU205 (HCU04)
output port is high voltage and pin 6 of it is low voltage to reset chip U201 (MT1389) and chip U214
(FLASH). When charge of the capacitor is close to 3.3V, triode Q204 cut off; pin 5 of phase inverter
input port is low level; phase inverter outputs high voltage from pin 6 and MT1389 reset finishes. After
reset of MT1389, reset signal is also given to sound D/A conversion chip CS4360 and sound A/D
conversion chip CS5340V for their resetting.

3.2.5 Clock circuit
1. The circuit schematic diagram is shown as the figure 3.2.5.1.
Figure 3.2.5.1 Clock circuit
Note: Elements marked with “X”symbol are those unused in practice.
2. Working principle: 27MHZ clock provides working clock for system. When powering on, capacitor
C275 and C276 will generate a concussion, so a vibration occurs on crystal oscillator. After several
times of feedback, a stable 27MHZ clock signal is finally generated on crystal oscillator.The function of
phase inverter is to increase feedback coefficient and for isolation.
3. This circuit may probably cause these troubles: power supply not connected; not read disc;
colour distortion of picture and no colour of picture.
Note: DC voltage of point A and B is 1.47V when in normal working.

2. Working principle:
To prolong the service life of electric machine and decrease the influence of start-up concussion
current to the machine, when there is disc in, the development personnel design the main axis electric
machine in running state always. Even though “STOP”button is pressed, disc will not stop running
immediately. Thus when pressing “OPEN”button, a braking signal is required to make the main axis
electric machine stop running to fulfill the completion of opening disc tray in a short period. In the course
of playback,
Press “OPEN" button and main axis drive signal disappears. For the reason of inertia, the main axis
electric machine is still in running state, and now the induced voltage achieved by the induced
electromotive force which is generated by electric machine's running on sampling resistor R321 and
R340 outputs from pin 34 through resistor E319, R320 and pin 36 of MT1389 after being processed
inside MT1389 and magnified, then sends to pin 47 of MT1389 through R13; after A/D conversion and
the corresponding processing inside MT1389, an instant electric machine reversal braking signal is
outputted from pin 37 of MT1389 to make the main axis electric machine decrease speed. When
MT1389 detects the disc stops running, disc tray will open to ensure that disc will not run when disc tray
opens.

Figure 3.2.8.1 Mute and power-0ff quieting circuit
2. Working principle: under the control of I2 C to MT1389, CS4360 sends 3 mute control signals,
MUTE1, MUTE2, MUTE3 from pin 28, 25 and 18 which is added to mute circuit. The generated mute
control signal MUTE-1 is added to the base electrode of each switching tubeQ205 - Q210 of 6-path
analog channel to make the switching tube and make audio signal bypass into ground to reach the
purpose of mute. The working mechanism is that when no audio signal comes to a certain path, CS4360
changes the mute control signal corresponding with this path to high level. After pressing MUTE button,
3-path mute signals all change to high level.
When working normally (playing discs), only one path signal of the 3-path signals, MUTE1, MUTE2
and MUTE3 changes into low level, now Q211 is on. The collector electrode of Q211 is high level; Q212
is also on and its collector electrode is low level; Q218 is cutoff; MUTE-1 is low level and sound outputs
normally.
When muting, MUTE1, MUTE2 and MUTE3 outputted by CS4360 all change into high level. At this
time, for the base electrode of Q211 is high level, Q211 is cutoff and Q212 is also cutoff. The emitter
electrode of Q218 changes into high level and also is on. +9V voltage is added to MUTE-1 through
Emitter Collector of Q218, the outputted high level is added to the base electrode of switching tube
Q205~Q210. The switching tube is on and sound is bypassed to ground.
- 22 -
Power-off quieting: when working normally, because there is no forward bias, Q219 is in cutoff state.
When powering off, +9V disappears and the base electrode of Q219 changes into low level. For
capacitor TC235 discharge is high level to the emitter electrode, Q219 is on. The discharge of TC235
makes MUTE-1 outputs high level and add to each switching tube through Emitter-Collector of Q219 to
make the switching tube on and sound is bypassed to ground to realize the function of power-off quieting.
Power-on quieting: when powering on, VCC is connected to power supply, voltage of the two ends
of Tc238 cannot change suddenly. The base electrode of Q211 changes into about 5V and then Q211 is
cutoff, Q212 is cutoff and MUTE-1 changes into about 1.68 to perform power-on quieting function.
The function of -9V voltage in the figure is to ensure the secure cutoff of each switching tube when
circuit is working normally.

3.2.9 Servo circuit
1. DK1005S adopts SANYO 62 decoder and MTK decode solution (MT1389+FLASH (16M)+
SDRAM (64M)). The servo circuit is mainly composed of front signal processing, digital servo
processing, signal processing IC T1389 and drive circuit D5954, in which MT1389 is the main
component of decode circuit at the same time.
2. The circuit functional block diagram is shown as figure 3.2.9.1.
The Explanation to the block diagram:After powering on or disc in, disc identification circuit
identifies the disc inserted into loader, and judges whether the disc is CD or DVD to conduct the
corresponding control. At the same time, MT1389 adjusts laser output power through laser power
control circuit. Pin 20 of MT1389 is VCD laser power strongness/weakness detecting signal input pin,
pin 21 is DVD laser power strongness/weakness detecting signal input pin, pin 23 is VCD laser power
drive control output pin and pin 22 is DVD laser power drive control output pin. When reading VCD disc,
if pin 20 detects laser output power is too strong, output voltage of pin 23 of MT1389 increases and onstate of V302 decreases to make the voltage provided for pick-up decrease and light emission of laser
head become strong.

After loader reading disc information, A, B, C, D, E, F signals are sent out to Mt1389 (DVD only
has A, B, C, D signals), and then inputted from pin 2~11, 18, 19 of MT1389. After being amplified and
processed by the pre-amplifier inside MT1389, now signals are separated to two part s for processing
inside Mt1389:
After being processed by digital servo signal circuit inside MT1389, one part
of signal form
corresponding servo control signals and output FOO, TRO, DMO, FMO digital servo control signals from
pin 42, pin 41, pin 37, pin 38 of Mt1389 respectively, then change into analog servo control signal FOSO,
TRSO, DMSO, FMSO through integration circuit composed by resistor capacitor, and send to driver
circuit BA5954 for amplification to bring along focus coil, trace coil, main axis electric machine and feed
electric machine after drive amplification. Among these, focus and trace servo are used to correct
objective position accurately; feed servo is used to bring along laser head to make radial large-scale
move which belongs to the preliminary adjustment to pick-up position;and main axis servo is used to
control main axis electric machine to make it read signals in means of constant linear velocity and bring
along disc to rotate.

After processing of amplification by VGA voltage control amplifier and equalization frequency
compensation inside MT1389, another part of signals are changed into digital signals through internal
A/D converter. When loader is reading CD/VCD signals, these signals are conducted EFM demodulation
inside MT1389, and then outputted to latter stage for AV decoding after finishing CIRC (Cross
Interleaved Reed-Solomon Code) error correction inside. When loader is readingDVD signals, these
signals are conducted ESM demodulation inside MT1389, and then sent to latter stage for decoding
after finishing RSPC error correction inside.
The other part of servo is open/close disc tray circuit. After panel or remote controller emits
open/close disc tray signal toMT1389, in usual conditions, TROPEN and TRCLOSE sent out by pin 39,
51 of Mt1389 are both low level, when signal of “open”comes, after Mt1389 makes disc stop rotating
through main axis braking circuit, TRCLOSE is set high to make open/close electric machine on loader
frame run to bring along dist tray to eject. After disc tray ejecting to proper Signal of opening to proper
position (TR_OUT) is set high level (0V) through the detecting switch on loader frame, MT1389 pulls
down TRCLOSE and open/close electric machine stop running. When MT1389 receiving “close”signal,
TROPEN is set high level by MT1389, open/clode electric machine tuns conversely to bring along disc
tray to close. After disc tray closing to proper position, signal of closing to proper position (TR_IN) is set
low level through the detecting switch on loader frame, MT1389 pulls down TROPEN and electric
machine stops running to finish “close”process.
3. Explanation to servo terms
FOO: when rotating, disc may probably move upwards or downwards slightly to make the focus of
laser emitted by pick-up cannot justly fall on data pit of disc, so pick-up is required to move upwards or
downwards to make focus aim at data pit justly. When pick-up is moving upwards or downwards, it
means that pick-up is making focus acts.
TRO: data information is save in disc in form of tracks. The process when pick-up moves from one
track to another one to read data is trace. In this process, it is objective, but the entire pick-up, that
moves forwards or backwards, and the moving range is very small.
FMO: similar to acts of trace, the acts of feed are larger than those of trace. Feed conducts a large
scale movement firstly, and then trace moves slightly in this range. Feed moves for a while, and does
not move for another while; but trace moves all the time. Feed is rough adjustment and trace is fine.
DMO: it is the top that holds up disc. Its rotation speed decides that of disc. Its rotation is generated
by an individual DC electric machine, in which rotation speed of DVD is twice over that of CD.
Hint: In order to observe these processes, you may take down upper cover of the machine, and
then the loader cover board. When power on with no disc in or disc in after disc out, you may observe
that pick-up returns to inner ring firstly and then springs back for a little distance, which is feed process.
Then pick-up will emit light and you may notice the objective moves upwards and downwards, which is
focus process. In face, in the same time of focus, the objective also moves upwards and backwards to
- 25 -
Make trace acts. Because the range is small, it is not easy to observe, and meanwhile DEMO disc tray
also rotates slightly, which is DEMO acts.

2. Working principle: this decode circuit is mainly composed of Mt1389, SDRAM and FLASH. The
important conditions for decode circuit working:
(1) Reset: refer to reset circuit working principle for details.
(2) Clock: this system adopts 27M external clock input and produces the clock signal required
inside system through internal frequency doubling circuit.
(3) Power: decode chip adopts two groups of power supply: 3.3V and 1.8V, in which 1.8V is
provided for internal logic control circuit, so we call care voltage.
After power on, reset circuit performs reset to CPU (8032) and FLASH inside Mt1389, decode chip
outputs reset signal at the same time to perform reset to other circuit. After system reset, read signal is
sent out to FLASH to read the information saved in FLASH and machine displays power on picture.
Servo system begins to work to check whether machine closes to proper position and whether switch is
turned off, if not, close action is performed. After door detect switch is turned off, the machine begins to
carry out the preparation work for reading disc and panel display at the same time.
Playback process: laser head picks up disc signal from disc, after being processed by servo
system, and sends it to decode circuit for decoding, and signal after being decoded is saved in SDRAM
- 26 -
Temporarily; when machine needs to replay signal, decode circuit calls the information inside SDRAM
for output.
Save user's information: information set by user is saved inside EEPROM, if users do not renew ot
reset this information, it will be saved inside IC forever.
Audio, video output circuit: at present, MT1389 integrates to video D/A converter, MT1389E
integrates audio D/A converter inside, and manufactures may select according to their own needs, so
when decode audio outputs, part of analog output is digital output. Please refer to circuit diagram and
audio circuit introduction for details.

2. Working principle: R261 is a matched resistor, which makes the signal achieve the maximum
power on load. Capacitor C289, C290 and inductor L243,compose a lowpass filter which filters the high
frequency interference signals beside useful ones; diode Vd210 and Vd211 compose a limiter circuit.
It is known from features of diode that the maximum amplitude of colour difference signal C cannot
exceed 5.7V and the minimum one cannot be under -0.7V, thus the high voltage signal from TV set can
be avoided burning down the player. Please refer to video signal flow diagram for details.

4. Working principle: digital audio signals SDATA0, ASDATA1 and ASDATA2 after being decoded by
U201 (MT1389) are outputted to pin 2, 3 and 4 of U207 (CS4360) from pin 217, 218 and 219 of U201
(MT1389) respectively, among which the function of 33ohm resistor is to prevent electromagnetic
interference. The above three-path digital signals, through CS4360 D/A conversion, output left/right
channel analog audio signal from pin 27 and 26; output left/right channel mute control signal MUTE1
from pin 28; output surround left/right channel analog audio signal from pin 24 and 23; output surround
left/right channel mute control signal MUTE2 from pin2;
output centre subwoofer analog audio signal from pin 20 and 19 and output centre subwoofer mute
control signal MUTE3 from pin 28. When a certain path signal has input, the corresponding analog
signal of this path has output, and the corresponding MUTE signal is low level, or else it is high level.
He used three-path clock signals of U207 (CS4360) are the same with those of U210 (CS5340).
U210 (CS5340) is to converse the analog OKA into digital signal and then output from pin 4 of U210
(CS5340), then into pin 224 of MT1389 and form echo with OKA signal which is connected to the
operational amplifier after being processed inside U201 (Mt1389).

2. Working principle
A: The working range of this switch power is AC 110V~250V. The voltage value here is 1.414 times
of effective AC value.
(1) Electromagnetic interference filter circuit: for various electromagnetic radiation exits in
surroundings, the inputted current will be disturbed. The function of electromagnetic filter circuit is to
remove these interferences by filtration to make those which enter the bridge rectification circuit are
relatively pure 220V AC.
(2) Bridge rectification and filter circuit: the function of this circuit is to generate a DC about 310V to
provide usage for future.
(3) Start circuit: when power-on just starts, transformer has not started working, and now the start
circuit provides a power supply voltage for FSDH321 to make it work.
(4) Absorption loop: The waveform of pin 2 of switch module FSDH321 sometimes is high level, and
sometimes is ow level, so a strong self-induction voltage will generate in primary coil of transformer and
FSDH321 may probably be caused damage. The function of absorption loop is to form a loop for this
self-induction to ensure the normal working of circuit.
(5) Rectification diode: The voltage which is just outputted from transformer is pulsating DC. The
function of rectification diode is to change pulsating DC into DC together with the later filter circuit.
(6) Feedback loop: The length of time of “on’and “off”within the same cycle inside switch module
FSDH321 is decided by the feedback loop. Feedback loop samples the +3.3V output port voltage. When
the output port voltage is too high, the sampled voltage is on the high side. Through feedback loop, it
changes the ratio of occupying space of pin 2 of FSDH321 to decrease the time of on-state. The
coupling quantity of transformer decreases and outputted voltage starts decreasing. When the outputted
- 30 -
Voltage is too low, the sampled voltage is on the low side. Through feedback loop, it makes the ratio of
Occupying space of FSDH321 increase. The coupling quantity of transformer increases and outputted
voltage starts increasing. Through the function of feedback loop, it makes power board output relatively
stable voltage. LM431 used in this power supply is a 2.5V comparison device, which is compared with
sampling voltage. When sampling voltage is more than 2.5V (means output voltage is on high side),
LM431 is on, and light emitting diode in photoelectric coupler starts emitting light to make the other side
of photoelectric coupler starts being on. The light emission of light emitting diode is stronger, the onstate degree is larger. The on time of switch module FSDH321 decreases, the coupling quantity of
transformer decreases and the outputted voltage starts decreasing. When sampling voltage is less than
2.5V (means output voltage is on low side), LM431 is cutoff. The on time of FSDH321 decreases, the
coupling quantity of transformer decreases and output voltage starts increasing. Through auto control
function of feedback loop, it makes power board output relatively stable voltage.
(7) Filter circuit: its function is to generate a stable and small-curve DC voltage. “∏" shaped filter is
usually adopted in filter circuit. The feature of capacitor filtering is that load resistance is high. When
current is small, the function of filtering is obvious. But the feature of inductor filtering is that load
resistance is small. When current is large, the function of filtering is obvious. If the capacitor is
constructed to “∏" shaped filter, it can perform better filtering effect.

2. Working principle: MIC part: when microphone is inserted into MIC left, DET signal changes from
low level to high level, which makes mute circuit of decode part off, no matter disc reading is available,
audio signal may output. If this signal has trouble, MIC will have no sound when playback stops. After
being filtered, signals inputted in MIC transmit to pin 5 of U601, and signals after discharge output from
pin 7 of U601, after being amplified for the second time, they are outputted from pin 1 of U601 to decode
board directly for Karaoke signal processing and output overlapped with audio signal to realize Karaoke
function.

Section Three Servicing Cases
3.3.1 Servicing cases
【Example 1】Symptom: power on automatically
Description: after connecting to power, do not press POWER button, power indicator light is on and
machine starts up at the same time.
Analysis and troubleshooting: use multimeter to test each channel voltage output of power board
and find that there is no CPU3.3V, other channels are normal; check elements in this channel and they
are all normal; test pin 9 of transformer and find that there is no voltage output; after checking, open
circuit happens between pin 9 and 13 of transformer; after changing transformer, trouble is removed.
【Example 2】Symptom: loader is loud
Analysis and troubleshooting: after closing to proper position, loader gives a click sound; check
loader and find that after laser head reset is ok, it does not retract quickly, but in reset all the time; push
laser head close to main axis electric machine, use multimeter to test pin 3 (LIMIT) of Xs306 and it has
open circuit to ground; check feed switch and find that this switch has lost effect; after changing switch,
machine is OK.
【Example 3】Symptom: door not open
Description: light emission, main axis and feed are all normal; press OPEN button but not any acts
happens.
Analysis and troubleshooting: use multimeter to test the voltage output of pin 3 of the 5P flat cable
XS306 from frame to decode board (open to proper position test) and it is +1.6V, which should be +3.3V;
test the resistor from pin 3 to 1389 and it is 330 ohm without trouble, so we doubt that 1389 has trouble;
after changing 1389, machine is ok.
【Example 4】Symptom: no picture, no sound and no screen display
Step 1: check all voltage of X203, and they are all normal.
Step 2: check output voltage of U209 (1.8V voltage regulator) and it is 1.9V, which is normal; check
pin 37 of U214 (flash) and it is 3.23V, pin 1 of U211 (SDRAM) is 3.19V, pin 14 of U205 (HCU204); pin 8 of
U202 (24LLC02) and it is 3.21V, which is normal.
- 35 -
Step 3: use oscillograph to test frequency of crystal oscillator X201 and find that there is no
waveform; check start-up capacitor C275 and C276 and find that resistance of two ends of C275 is 100
ohm, so this capacitor has electric leakage; after changing it, the machine is ok.
【Example 5】Symptom: component vide has no output
Step 1: after checking, we find that composite video is normal, so we can preliminarily determine
that component video output part has trouble.
Step 2: use oscillograph to test 3 component video output pins of pin 200 (Y4) of U201 (Mt1389),
pin 202 (Y5) and pin 203 (Y6, and we find 3 have waveform output, so we may judge that trouble does
not lie in Mt1389, but in output circuit.
Step 3: in the 3 component video, only when brightness signal has trouble, there is no output, so we
directly check the path of brightness signal. Check brightness signal Video-Y4 of pin 11 of flat cable
holder XS204 and find that there is no waveform output, so we can judge that trouble lies in decode
board.
Step 4: check anode of catching diode V216, shown in the figure 3.6.1, and there is still no
waveform, so we can confirm that trouble lies in filtering circuit n=matching resistor. R273 is matching
resistor, Vd216 and Vd217 are catching diode, and L246, 213, C298, C299 comprise filtering circuit.
Step 5: use multimeter to test above circuit elements and no problems are found, but in the above
circuit, point A has no waveform; carefully observe L246 and it has rosin joint; after well welding it,
component video output resumes normal.
【Example 6】Symptom: color distortion of component video
Step 1: use oscillograph to check YpbPr terminal and find that Pb terminal has no signal output.
Step 2: use oscillograph to check Y5 signal (pin 202 of 1389 or high level end of R276), and no
abnormality is found.
Step 3: use oscillograph to check VIDEO-U signal (Vd218 anode) and VIDEO-U and they are
normal.
Step 4: use oscillograph to check two ends of L247, L214 and find that L247 has open circuit; after
changing L247, machine is normal.
【Example 7】Symptom: component video has no output
After checking, composite video output is normal, when using oscillograph to test pin 200, 202 and
203 of MT1389, they all have no output; composite video is normal, so we preliminarily judge that trouble
does not lie in clock circuit and power supply circuit; change MT1389 directly and component video
output resumes normal.

【Example 8】Symptom: there is picture but no sound
Step 1: all channels have no sound, so trouble is certain to lie in the common part of these channels.
Common part of these channels: 1. Power supply voltage of 4558. 2. MUTE-1 signal in mute. 3. CS4360
has trouble. 4. MT1389 has trouble.
Step 2: check power supply voltage (土9V) of 4558 from simple steps and it is normal.
Step 3: use multimeter to test C electrode of voltage Q218 of MUTE-1 signal and it is high level
(1.68V), so trouble may probably lie in mute circuit.
Step 4: in mute circuit, to make MUTE-1 be 1.68V, Q212 is sure to be cutoff. To make Q212 cut off,
cathode of VD207, VD208, VD209 must be high level; but when using multimeter to test cathode of
VD207, it is low level, Q212 should be on in normal conditions; so we decide that Q212 may probably
have trouble.
Step 5: change Q212 and trouble is removed.
【Example 9】Symptom: mixed right channel has no sound.
Step 1: use oscillograph to check R terminal and confirm that there is no output.
Step 2: use oscillograph to check pin 26 FR signal of U207 (CS4360) and output is normal.
Step 3: check waveform of RT signal (pin 19 of XS204 or C electrode of Q205C) and it is normal.
Step 4: check waveform of pin 1 of U219 (4580) and the output is normal.
Step 5: use multimeter to check C electrode resistance to ground of Q205 and it is zero, so we
doubt Q205 has trouble; after changing Q205, machine is normal.
【Example 10】Symptom: power not on after switching on machine
Step 1: check voltage of pin 7 (5V), pin 9 (3.3V) and pin 11 (5V) of Xs203 and it is normal, so ie is
estimated that trouble lies in decode board.
Step 2: check voltage of pin 2 of U209 and it is 0V (which should be 1.9V in normal condition).
Step 3: check R242 and R243 resistance and it is normal, so we estimate that U209 is damaged.
Step 4: after changing U209, machine is normal.
【Example 11】Symptom: there is picture but no sound
Step 1: each channel has no sound, so trouble lies in the common part of each channel.
Step 2: check mute signal MUTE-1 (one end of R2118) and it is -0.98V, which is normal.
Step 3: check power supply of U207 (CS4360) and it is normal.
Step 4: use oscillograph to test pin 26, 27 of U207 (Cs4360) and find that there is no waveform
output; use oscillograph to test pin 2 of U207 (Cs4360) and there is waveform input, so we preliminarily
judge that U207 has trouble.
Step 5: after changing U207 (Cs4360), trouble is removed.

【Example 12】Symptom: not read disc
Step 1: check the nerve flat cable socket on Xs301 and no abnormality is found.
Step 2: change loader, disc reading is normal and trouble is removed.
【Example 13】Symptom: not read disc
Step 1: check Xs301 flat cable and socket and there is no abnormality.
Step 2: change loader but trouble still exists.
Step 3: check power supply, observe laser head main axis and feed and they are normal, but no
focus.
Step 4: check D5954 power supply and reference voltage and they are both normal.
Step 5: check MT1389 power supply with reference to “MT1389 power supply troubleshooting”.
Step 6: check the path between pin 42 (focus error signal output) of MT1389 and pin 1 of D5954,
after changing C213, trouble is removed, so it shows that C213 has electric leakage.
【Example 14】Symptom: not read disc
Step 1: check flat cable and socket on XS301 and there is no abnormality; change loader and trouble still
exists.
Step 2: when no disc in, after closing door, we find that when lease head is making focus and trace acts, the
emitted DVD light is not strong enough, so we preliminarily judge that laser power control circuit has trouble.
Step 3: when using multimeter to test V301 and V302, we find that V301 is stricken through; after changing
V301, trouble is removed.
【Example 15】Symptom: machine down in the course of playing
According to former experience, this type of trouble may probably occur in MT1389, so change MT1389
directly and trouble is removed.
Conclusion: for this type of trouble, firstly change Mt1389, if trouble cannot be removed, change U211 (SDRAM),
if it cannot be removed again, change U214 (FLASH).
【Example 16】Symptom: power not on
Step 1: check voltage on XS203 flat cable holder and all are normal; check power voltage on U201 (MT1389),
U211 (SDRAM), U214 (Flash), U202 (24LLC02) and it is also normal.
Step 2: check reset circuit, and reset by force, and power is still not on; check clock circuit and clock frequency
is normal.
Step 3: change U217 (flash) and trouble is removed.
Conclusion: when power supply, reset and clock are all normal, for this type of trouble, firstly change U214
(flash), and then U201 (MT1389) or U211 (SDRAM).

Section Four Waveform diagram
This section collects signal waveform diagram of audio, video and each unit circuit with the purpose
to help servicing personnel to judge where trouble lies in accurately and quickly to improve servicing
skills. For the difference of oscillograph's type, model and tuner, a certain difference may exist, so the
servicing personnel are expected to pay more attention to check in daily operation.

Section Five Function Introduction to IC
3.5.1 function introduction to MT1389
1. MT1389 (U201) adopts LQFP pin 256 casing and 3.3V/1.8V dual voltage working mode, which is a
good performance large-scale CDROM front-end processing CMOS integrated circuit, and CD/VCD/DVD
player special-used single chip. It includes focus servo error magnification, trace servo error magnification
and horizontal output servo control. The main function are narrated as follows:
(1) The main function of front-end RF small signal processing is to process and amplify signals A, B, C, D,
E and F transmitted from pick-up, and automatically adjust laser output power, meanwhile fulfil the
identification of VCD disc and DVD disc.
(2) Digital servo processing may produce focus, trace, feed, main axis servo control signal processing
and digital signal processing to realize modulating EFM/EFM+ of Therefore signal.
(3) MPEG1/MPEG2/MPEG4/JPEG Video decoder. This chip can decode VCD, DVD, MPEG 4 network
video, compatible with “network movie”disc, and also can read JPEG picture to fulfil digital album playback.
(4) In audio aspect, AC-3/DTS dual decoding, actively read MP3, compatible with DVD Audio decode, to
reach high resolution sound quality restore 1000 times higher than that of CD.
(5) By using the built-in 8032 micro-processer of chip, MT1389 may also fulfil the control of the player
system to simplify circuit design greatly.
(6) Deal with data transferred from tuner and control the tuner.

Infrared receiver HS0038A2 or HS0038B has three pins: power supply anode (pin 2), power supply
cathode (pin 1) and data output port (pin 3). If 5V is used for power supply, when keeping the state, voltage of
data output port is also 5V (HS0038B requires pull-up resistor). The internal part is composed of infrared
receiving diode and amplification circuit. To reduce the interference of visible light to working, diode part of
infrared receiving usually adopts black resin casing to filter the beam with waveform length below 700nm. The
amplification circuit is composed of an integrated block and elements of resistor and capacitor (including
amplification, frequency selection and demodulator circuit), cased inside a screen-shielded box.

3.5.10 Function introduction to U501 (FDSH321)
Pin 6¡¢7¡¢8 of 5L0380 is controlled by feedback pin 3 to make it on for a while and off for another while to
form pulse DC to control coupling quantity of transformer. When secondary output voltage of transformer is on
the high side, under the control of pin 3, disconnection time of pin 6¡¢7¡¢8 gets longer and coupling quantity of
transformer decreases to make output voltage get lower gradually; when secondary output voltage of
transformer is on the low side, disconnection time of pin 6¡¢7¡¢8gets shorter, connection time gets longer
(connect inside fsdh321), coupling quantity of transformer decreases and secondary output voltage gets
larger gradually. Pin function is shown as the following table:

3.5.11 Function introduction to ncp1200
the NCP1200 represents a major leap toward ultra¨Ccompact Switch¨CMode Power Supplies. Thanks to
a novel concept, the circuit allows the implementation of a complete offline battery charger or a standby
SMPS with few external components. Furthermore, an integrated output short¨Ccircuit protection lets the
designer build an extremely low¨Ccost AC/DC wall adapter associated with a simplified feedback scheme.
With an internal structure operating at a fixed 40 kHz, 60 kHz or 100 kHz, the controller drives low
gate¨Ccharge switching devices like an IGBT or a MOSFET thus requiring a very small operating power.
Thanks to current¨Cmode control, the NCP1200 drastically simplifies the design of reliable and cheap offline
converters with extremely low acoustic generation and inherent pulse¨Cby¨Cpulse control.
When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC
automatically enters the skip cycle mode and provides excellent efficiency at light loads. Because this occurs
at low peak current, no acoustic noise takes place. Finally, the IC is self¨Csupplied from the DC rail,
eliminating the need of an auxiliary winding. This feature ensures operation in presence of low output voltage
or shorts.

3.5.12 Function introduction to U503 (LM431A)
U503 (LM431A) is a 2.5V comparator, shown as the figure 3.5.12.1. Compared the inputted voltage of
- 81 -
R end with 2.5V, when voltage of R end is more than 2.5V, KA end is on and photoelectric coupler starts to
send out photocurrent; when voltage of R end is less than 2.5V,
KA end is cutoff and photoelectric coupler
does not send out photocurrent. CPU+3.3V in power board circuit must be kept in 3.3V, for the function of
comparator. No matter more than or less than 3.3V, through on and off status of comparator, it will control the
on state of the output end of photoelectric coupler LM431A to adjust the output space occupation ratio of
switch module to control the output voltage of transformer and masthead the power supply of the whole
system.

3.5.13 Function introduction to U502
U502 (2501) is a photoelectric coupler, shown as the figure 3.5.13.1. The right side is a light emitting
diode, which sends out light of different intensity according to the strength of voltage inputted from the right
side, generates photocurrent of different intensity on the left side according to light of different intensity, and
outputs from position D. The higher of the voltage inputted from the right side, the stronger of the light emitted
from light emitting diode and the larger of the photocurrent produced from position D. The lower of the voltage
inputted from the right side of photoelectric coupler, the weaker of the light emitted from light emitting diode
and the weaker of the current outputted from position D.

As for decode board working principle of this player, it only cancels headphone signal loop on the
basis of DV717SI, AV board working principle is the same with that of DV717SI, only PCB board is
different. We will mainly introduce differences, and now we will introduce MIC board, main panel and
power board working principle of DV721SI.

2. Working principle: this machine includes two-way MIC input, which adopts 9P MIC holder with
quieting function and dual-channel volume adjustment function. After inserting microphone and begin to
sing, signals inputted by MIC are inputted to pin 3, 5 of U601 respectively for amplifying and then output
from pin 1, 7 of U601 and then twp paths are divided. One path, after volume adjustment through
potentiometer, inputs from pin 2 of U602 for mixed amplifying and outputs from pin 1 through flat cable
holder XS601 to power board and decode board. The other path, enters the comparator composed by
U602B through R623/R618, when input signal is up to a certain range, DET pin has high level output,
mute circuit controlled by decode chip does not mute; when input signal is not enough, DET is level.
VD601 VD602 in circuit are protection diode and VD603 is rectification diode.
7.3.2 Control panel circuit
1. Control panel block diagram is shown in the figure 7.3.2.1:
2. Working principle: after power on, power board only has 3.3V voltage output, pin 2 of power
board standby IC U505 outputs high level and lightens standby light in red, other circuits do not work.
After power on, each voltage output is normal, pin 6 of U505 outputs high level, and high level of pin 2
turns off at the same time, standby light turns off, and power board begins to supply power for each
circuit.
Decode system begins to start up, main panel U402 obtains power supply and outputs high level in
P2/S2 end, +5V power, through U404 voltage regulating, outputs 3.5V power from pin 2 to supply power
for LED402 LED403 of background light board through V402 to make background light on, at the same
time, Sw1 outputs high level Ks1, OSC circuit begins to work, and panel button module enters ready
state. If K12 is low level, buttons have no function.

At the same time, P1/S1 outputs high level to make the blue background light of mirror on and
background light may be turned on and off through firmware. Decode chip gives out display data to
Pt6554 to make it drive LCD to display.
Remote control principle: remote control receiver lies in subsidiary panel, which is supplied power
by CPU3.3V, remote control signal IR is divided into two ways: one path arrives at decode board through
main panel to realize operation functions; the other way realizes remote control power on through power
board standby control circuit.

2. Circuit principle: through power socket, protector tube, voltage dependent resistor R501,
common mode rejection BC501 and L501, 220V AC is added to the bridge rectification circuit composed
by D501-D504. Diode adopts good performance In4007 which has higher voltage resist value than
In4001. 310V DC that outputs after bridge rectification, through TC517, C502, C503 filtering, is added to
2-4 winding of transformer YR501 and sent to pin 5 of switch module after rectification. The switch
module start voltage is not sent by D506, R505, but taken from 311V of pin 8 and achieved after being
processed inside IC. R503, C502, D505 and C503 compose absorption loop to provide discharge loop
of reverse electromotive force for transformer 2-4 winding. Transformer 6-7 winding, through D506 half
wave rectification, TC502 and R502 filtering, provides about 10V power for pin 6 of NCP1200. Pin 2 of
NCP1200 is feedback control pin, which controls the on state of internal field effect tube to make output
voltage stable. Pin 4 of NCP1200 is connected to ground, pin 8 HV is connected to high voltage line, pin
5 DRV drives output of external MOSFET, which belongs to current control type, drain electrode max
limit current 110mA and working frequency is 40kHz, 60kHz.
3. Five branch circuits are divided for those coupled to secondary level through transformer
(1) Voltage outputted by secondary level 16 pin, through D513 half rectification, controllable
silicon, TC515 and filtering, outputs CPU3.3V to supply power for CPU;
(2) Voltage outputted by pin 15 of transformer, through D508 half wave rectification, TC503, L505
and TC504∏ -type filtering, +9V is achieved, then SA+5V through LM7805 voltage regulating, which
supplies power for decode board.
(3) After half wave rectification, ∏ -type filtering, pin 12 voltage of transformer outputs 3.3V to
supply power for decode board through D515;
(4) After D511 half wave rectification, ZD502 voltage regulating, pin 9 voltage of transformer
outputs -9V to supply power for audio circuit.
We should mention that voltage outputted from secondary level of transformer is pulse DC, so
stable DC level may be achieved only through half wave rectification. Diode of half wave rectification
adopts quick recovery diode, which works in high frequency state, so we cannot substitute with common
diode.
Feedback sampling of switch power is from 3.3V (DC power off is from CPU3.3V, power on is from
+3.3V) and supplies for photoelectric coupler 2501 through D516 and R506, and sends to R pin of 2.5V
comparator through R508 and R509. When 3.3V is on high side, KA pin of comparator LM431A is on,
and then sent to pin 4 of switch IC268P through 2501 photoelectric coupling to decrease the on time of
inside switch to decrease the coupling of transformer and the outputted 3.3V to reach the purpose of
auto control. Vice verse.
This machine has DC power on/off function, so switch power has been designed a power
management part with main elements U403 12C508A. It is a programmable logic controller responsible
for DC power on/off and LED indicator light control. This p-layer is also with this function, no matter
- 114 -
When the machine is on or in standby, high voltage [art of power board, 3.3V output, sampling and
feedback circuit are all in working state.

5. Standby working principle: shown in the figure 7.3.3.3, when working normally, after pressing
STANDBY button (or remote controller STANDBY button), SW1 produces a low level, pin 2 of U505
receives the pulse of low level, and outputs a low level signal from pin 5 to make triode V502 cut off;
when Tc515 anode is more than 3.3V, it feedback to U503 and make U501 decrease “On”time through
U502 and make voltage stabilize in 3.3V, for the winding group of pin 16 of TR501 is most, voltage is
highest, when TC515 anode is increasing to 3.3V voltage, other winding voltage is very low, and
machine cannot enter working state to realize standby.
Standby function of remote control is similar to panel button.

6. Working principle of power on: shown in the figure 7.3.3.3, Sw1 is equal to the input end of Dtype trigger inside U505, each time when Sw1 inputs a triggering level to pin 2 of U505, trigger turns
over once, that is pin 3, 5 turn over once. When the player is in standby state, pin 3 LED is defaulted
high level to drive panel indicator on; pin 5 STB is defaulted low level, that is V502 base electrode low
level.
When pressing POWER button on panel (or remote controller), SW1 inputs trigerring low level (or
IR inputs power-on signal) to P2 9P7) of U403, pin 3 of U505 changes to low level, panel standby
indicator light turns out; at the same time, pin 5 outputs high level to send to base electrode of V502 to
make it on, collector electrode changes to low level to make pulse signal of pin 3 of U506 short circuit to
ground, controllable silicon cuts off, pin 2 has no output, now CPU+3.3V is provided by +3.3V winding,
voltage at this time is low, so voltage increase quickly through feedback loop secondary level winding,
and outputs voltage to supply power for each part through rectification, filtering or voltage regulating.
