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 large-
scaleintegrated 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.

3. RFO=A+B+C+D.
4. Focus error signal=(A+C)-(B+D) Trace error signal=E-F.
2. Working principle
(1) Laser tube: loader DVD laser diode wave length is 650nm and that of CD laser diode is 790nm;
if wave length is between 370nm and 750nm is visible light, laser during the course of reading DVD disc
is visible light and that if IR light when reading CD disc.
(2) Principle of laser head pick-up signal: laser beam projects onto disc vertically. When focus of
laser beam projects into disc, laser beam will produce reflection and reach light detect device through
reflection loop and switch into electric signals through photo-epectric conversion. The reflection loop
produced in non-pit information area and pin information area on discs are different and reflect into
different areas of light detect device, the photo-elecric diode in different positions of light detect device
will produce different signals to process light detect device diode signals and then produce digital
signals.
(3) Focus and trace winding: when laser head is reading signals normally, information side should
be in the focus of laser beam. Because of disc error and some factors, such as high speed rotation nd
mechanical error, laser beam will deviate from information side unavoidably to produce phenomena of
deflection and de-focusing; focus and trace coil are added to adjust laser beam to make it focus in
information area correctly.
(4) RF signal formation: when reading disc normally, light detect device will have 160MV vague eye-
shape waveform that are superposed on A, B, C, D, through being superposed by adder inside light
detect device, output RF signals from RFO pin; frequency when reading DVD disc is far higher than that
when reading CD disc and output range is about 1.4V.

3.2.2 Servo circuit
1. Servo system of this player adopts SANYO 65 loader and MTK decode solution
(MT1389HD+FLASH (16M) +SDRAM (64M)), and its servo circuit is mainly composed of front end signal
processing, digital signal processing and digital servo processing, digital signal processing IC MT1389
and drive circuit Am58888, in which Mt1389 is also the main part of decode circuit. Servo circuit block

Figure 3.2.2.1 Servo circuit block diagram
2. Working principle: after power on or close to proper position (on loader frame for normal DVD, as
for PDVD, on PCB at the lower part of door), loader laser head begins to reset; after laser head reaches
proper position, detect switch will give a signal to Mt1389, Mt1389 begins to output focus, main axis and
light emission signals, machine begins to rotate, laser head begins to identify disc information and
decide whether disc is CD or DVD according to disc information to facilitate to output level from IOA pin
to make disc switch circuit and laser head PD IC make the relevant control action. At the same time,
Mt1389 adjusts laser output power through laser power control circuit.
After loader reading disc information, A, B, C, D, E, F signals are formed through photo-electric
conversion and 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. One part, through addition inside Mt1389 and
amplifying and subtraction circuit, produces servo error signal, after being processed by digital servo
- 19 -
Signal circuit, corresponding servo control signals form to output FOO, TRO, DMO, FMO digital servo
Control signals from pin 42, pin 41, pin 37, pin 38 of Mt1389 respectively, and FOSO, TRSO, DMSO,
FMSO, through integration circuit composed by resistor capacitor, and send to servo driver circuit for
amplification to bring along focus winding, trace winding, 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 laser head 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 reading DVD signals, these
signals are conducted ESM demodulation inside MT1389, and then sent to latter stage for decoding
after finishing RSPC error correction inside. Normal DVD player has a open/close circuit to control the in
and out of door to reach the purpose of coneying discs; PDVD adopts manual open means and whether
it is close to proper position can be checked by detect switch.
3. Explanation to servo terms
(1) FOO: when rotating, disc may probably move upwards or downwards slightly to make the focus
of laser emitted by laser head cannot justly fall on data pit of disc, so laser head is required to move
upwards or downwards to make focus aim at data pit justly. When laser head is moving upwards or
downwards, it means that pick-up is making focus acts.
(2) TRO: data information is saved in disc in form of tracks. When disc is rotating, trace deviation
will produce and now laser head is required to be adjusted. In this process, it is objective, but the entire
pick-up, that moves forwards or backwards, and the moving range is very small.
(3) 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
and acts are obvious when power on and selecting tracks.
(4) 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.

2. Working principle
Pin 20/21 of Mt1389 is laser power detect input pin, pin 21 is DVD laser power strong/weak detect
signal input pin, pin 23 is VCD laser power drive control output pin and pin 22 is DVD laser power drive
control output pin.
LDV33
When reading VCD discs, laser power becomes weak, voltage of MDI pin decreases, voltage of pin
23 of Mt1389 decrease to make voltage of pin 19 of Xs301 increase to reach the purpose of promoting
laser power. When laser power is too strong, voltage of MDII pin increases to make voltage of pin 23 of
Mt1389 increase to make voltage of pin 19 of Xs301 decrease to reach the purpose of reducing laser
power to form an auto power control circuit.
When reading DVD disc, pin 21 is detect signal input pin, pin 22 is drive control output pin and
working principle is the same with that when playing VCD disc.

2. Working principle: after loading disc into the machine, IOA end of ,Mt1389 is defaulted high level
to make Q305 saturated on and form loop with CD laser power control circuit on loader. At the same time,
IOA directly reaches loader PD IC for switch and disc begins to rotate. When servo processing system
identifies that disc in machine is not CD, IQA pin outputs low level to make Q305 cut off, Q303 is on and
forms loop with DVD laser power control circuit on loader to perform the action of reading DVD disc.
After disc tray opens, IOA still keeps the state before opening disc. If the machine cannot identify which
disc is in this machine, IQA pin will switch continuously until disc has been read or system judges that
there is no disc in.

Figure 3.2.6.1 Main axis control circuit diagram
2. Function: disc is always in high speed rotation state when machine is reading discs, when it is
necessary to open door and change another disc, MT1389 stops giving positive phase drive signals to
main axis drive circuit, but disc is still rotating due to the function of inertia. If the action of opening door
is carried out at this moment, disc will be worn, so the machine must apply brake to main axis. Whether
disc has stopped rotating or whether it is rotating reversely, decode chip cannot judge, so a main axis
control circuit is added to make decode chip can effectively monitor whether disc has stopped rotating.
3. Working principle: MT1389 has a built-in comparator composed of operational amplifier, in which
OP is the in-phase input end, OP- is reverse input end, OPO is output end. When playing normally,
electric machine is rotating in positive direction, voltage of OP+ is higher than OP-, voltage of OPO is
more than 1.4V. When it is necessary ti open disc door, main brake signals stop, electric machine is
eternal magnet, so when rotating, inductive electromotive force produces on two ends, through R320,
R319 sampling, to give to decode chip to make OPO output voltage lower than 1.4V and transmit to
MT1389 ADIN input pin through R318; when ADIN is high level, main axis does not make any acts, when

ADIN is low level, MT1389 outputs an instant electric machine reverse braking signal to make main axis

2. Working principle: this decode circuit is mainly composed of Mt1389, SDRAM and FLASH.
Important conditions for the working of decode circuit have:
(1) Reset: refer to reset circuit working principles for details.
- 25 -
(2) Clock: this system adopts 27M external clock input to produce the required clock signals through
inside doubling circuit.
(3) Power: decode chip adopts 2 groups of power supply: 3.3V and 1.8V, in which 1.8V is mainly
provided for internal logic control circuit, which is called core voltage by us.
After power on, reset circuit performs reset to Mt1389 built-in CPU (8032) and FLASH, decode chip
outputs reset signals at the same time and performs reset to other circuits. After system reset, read
signals are firstly sent to FLASH to read out information saved inside FLASH, machine displays
power0on picture, servo system begins to work and check whether door os closed to proper position and
whether detect switch is shut, if not, action of closing door is performed. After detect switch is shut,
machine begins to perform the preparations of disc reading and panel display.
Playback process: laser head picks up disc information from discs, through being processed by
servo system, and sends to decode circuit for decoding, and signals after being decoded are saved in
SDRAM. When machine required to replay signals, decode circuit calls out information inside SDRAM
for output.
Save user information: information set by users is saved inside EEPROM and will be saved inside
IC forever if users does not update or reset this information.
Audio, video output circuit: at present, Mt1389 integrates video D/A converter, Mt1389 integrates
audio D/A converter inside, and manufacturers may select according to their own demands, therefore
when in audio decode output, part is analog output and part is digital output. Please refer to circuit
diagram and audio circuit for details.

2. Working principle: after power on, voltage of Dv33 increases to 3.3V and main chip power supply
is normal. Now, Tc208 cannot change voltage of Dv33 suddenly, base electrode of Q201 has current in,
Q201 is saturated on, URST is low level. Dv33 charges Tc208 through emitter electrode of R219 and
- 26 -
Q201 to make voltage of cathode of Tc208 decreases gradually. When this voltage is below 0.7V, Q201
cuts off, URST changes into high level, and the process for URST from low to hgih is called low level
effective reset signals by us. After power off, voltage of Dv33 decreases, Tc208 and Dv33 voltage
decreases together, D201 performs surge discharge and clamping to TC208.

2. Working principle: MT1389 has built-in video D/A conversion circuit, video output has R/B/G,
Y/Pb/Pr, Y/Cb/Cr, CVBS, Y/C output mode, in which R/B/G, Y/Pb/Pr, Y/Cb/Cr, Y/C cannot output at the
same time and need software to switch. CVBS is a separate output mode, 4-channel video signals
outputted by MT1389, after video filtering and clamping, output to video terminal.
Shown in the figure 3.2.9.2, capacitor C287, C288 and inductor L227 compose a low-pass filter to
filter high frequency interference signals except for useful signals; dual diode D211 composes a
clamping circuit. It is known from features of diode that the most range of composite video signal CVBS
cannot be over 5.7 and cannot lower than -0.7 in minimum, thus high voltage signals from TV set can be
prevented from burning down the player.

2. Quieting circuit working principle:
When the player is working normally, shown in the figure 3.2.11.1, when chip is outputting analog
audio signals, it outputs s low level signal at the same time to
VMUTE to make Q211 on, voltage of
Q211B electrode is about 2.7V, voltage of Q211 collector electrode is about 3.3V, so Q212 is also on;
voltage of B electrode is about 0.7V, voltage of Q213 E electrode is close to zero, Q213 cuts off, MUTE-1
is negative voltage, which is added to base electrode of mute pipe of audio output end to make mute
pipe cut off and audio signals output after being amplified by 4558. When in mute, MT1389 has no audio
signals that output to operational amplifier, so audio output end of the player should have no audio
output; electronic elements in circuit and IC will produce some noise to transmit to audio output end of
the player, in order to filter these noise, decode chip outputs a high level signal to VMUTE to make Q211
cut off, so Q212 cuts off, +5V power transmits through E C electrode of Q213 to base electrode of switch
pipe Q205-Q210 and circuit is in mute.
When the machine is not playing discs, decode chip outputs a high level signal to VMUTE to make
circuit enter mute.
3. Power-off quieting working principle:
Shown in the figure 3.2.11.1, when the player is working normally,
D204 is on, +5V charges
capacitor TC235 through D204, now voltage of emitter electrode of Q214 is lower than voltage of base
electrode and Q214 cuts off. When power off, +5V disappears, Q214 base electrode changes to low
level, and its emitter base changes into high level because of discharge of TC235, now Q214 is on,
collector electrode of Q214 (AMUTE) outputs high level to add to the base electrode of switch pipe
Q205-Q210, switch is saturated, the noise produced in the course of power on and off is bypassed to
ground, and power-off quieting function is realised.

(1) Power grid filtering circuit: various electromagnetic radiation exits in surrounding, so it will
produce interference to inputted AC current. The function of power grid filtering circuit is to filter there
interferences to make those that enter bridge rectification circuit are comparatively pure 220V AC power.
(2) Bridge rectifying and filtering circuit: the function of this circuit is to switch city power into DC
power. Voltage after rectifying and filtering is 1.414 times of input power, so the DC voltage on two ends
of TC501 is equal to 300V.
(3) Absorption loop: power always works in on/off state, so very high peak voltage will produce in
the course of power on and off. In order to protect switch IC better, a peak absorption loop is added.
(4) Filtering circuit: the function is to produce a comparatively stable and small ripple DC voltage. In
filtering circuit, “ "-type filter is adopted most of the time. The features of capacitor filtering are that
when load resistance is high and current is small, filtering is obvious; as for inductor filtering, when load
resistence is small and current is large, filtering is obvious. To constitute capacitor into “ "-type filter,
better filtering effect may be achieved.
- 30 -
(5) Feedback loop: the time length of “on” and “off” in the same cycle inside switch module VEPR22
is decided by feedback loop. Feedback loop samples +3.3V output voltage; when output level is too high,
voltage after being sampled is on high side, through feedback loop, space occupation ratio of pin 3
signal of VEPR22 is changed, “on” time reduced and output voltage begins to decrease. When output
voltage is too low, voltage after being sampled is on low side, through feedback loop, space occupation
ratio of VEPR22 increases, output voltage increases. Through the function of feedback loop, power
board outputs stable voltage. LM431 used in this power is a 2.5V comparator. Compare sampling
voltage with this 2.5V voltage, when sampling voltage is more than 2.5V (output voltage is on high side),
LM431 is on, light emission diode in photoelectric coupler begins to emit light to make the other end of
photoelectric coupler begin to be on; light emission of light emission diode is stronger, the degree of “on”
is larger, the time of “on” of switch module VEPR22 decreases, output voltage begins to reduce. When
sampling voltage is lower than 2.5V (output voltage is on low side), LM431 cuts off, “on” time of VEPR22
increases and output voltage increases, thus, through he auto control function of feedback loop, power
board can output comparatively stable voltage.

2. Working principle
Panel control components are divided into main panel and subsidiary panel. Main panel is mainly
composed of LED screen, drive chip Pt6961, remote control IR sensor, button and indicator light;
subsidiary panel is composed of power button and power indicator light.
Function of U401 (PT6961) is to process data signals send from decode board to drive display
screen to display the corresponding state, and scan panel buttons at the same time, process button
information and then send to CPU in the means of data signal to control the player to make the relevant
action.
Pin 2 of remote control receiver HS0038B3V is 5V power supply pin, pin 1 is grounded, pin 3 is
output pin; receiver processes button information of remote control and then outputs from pin 3 to send
to decode board directly.

Analysis and troubleshooting: check laser head, light emission, feed, main axis and trace and they
are all normal but there is no focus action; use multimeter to test pin 13, 14 of U301 (5888) and voltage
is normal (about 1.4V), test pin 1, 2 of Xs301 and voltage is also normal, check nerve flat cable and
touch is good, so it is judged that laser head focus winding is burnt down; after changing loader, trouble
is removed.
[ Example 2] Symptom: power not on
Description: +5V, +9V, -9V, +3.3V have no output
Analysis and troubleshooting: check power board and find that each path voltage has no output,
check and find that 220V voltage input is normal, bridge rectification circuit has no voltage output; use
multimeter to test fuse tube and it has open circuit, change fuse tube and trouble is not removed, test
anode of TC501 and there is still no voltage output, fuse tube has been burnt down, check 4 diode of
bridge rectification circuit and they are all normal, TC501 has no abnormalities of leakage and striken
through, test pin 1 and 8 of U50 (switch IC) and it has short circuit, this IC has been stricken through;
after changing IC, trouble is removed.
[ Example 3] Symptom: no MIC
Description: when reading discs, sound and picture are normal
Analysis and troubleshooting: power on, use remote controller to turn on MIC, insert microphone
and speak, use oscillograph to test pin 4 (OK) of MIC board XS601 and find that there is no signal
output,Check voltage of pin 4, 8 (+9V, -9V) of U601 and it is normal; use oscillograph to test pin 5 o U601
(4558) and there is signal input, test pin 7 of U601 and there is no signal output, after changing U601,
trouble is removed.
[ Example 4] Symptom: no sound
Description: picture output is normal
Analysis and troubleshooting: test pin 1, 7 of operational amplifier of sound output circuit and there
is no signal output; test power supply voltage of operational amplifier and it is 9V, which is on low side;
- 35 -
After removing load, test power board 9V voltage output and it is normal, so we confirm that trouble lies
in decode board part. Only U209 of decode board has +9V power supply, test resistance to ground of pin
8 and it is 86, which is infinite in normal conditions; after changing U209, trouble is removed.
[ Example 5] Symptom: power not on
Description: switch on power, picture of the player has no output, panel has no OSD and panel
buttons have no function.
Analysis and troubleshooting: check power board and find that each path voltage has no output,
check and find that 220V voltage input is normal, check bridge rectification circuit and voltage output is
normal, test anode of TC501 and voltage is 310V, which is normal, test pin 1, 8 of U501 (switch IC) and
they are short-circuited, this IC has been stricken through; after clanging IC, trouble is removed.
[ Example 6] Symptom: not read disc
Description: not read any disc
Analysis and troubleshooting: check laser head, light emission, feed, main axis and trace and they
are all normal, but there is no focus action; use multimeter to test pin 13, 14 of U302 (5888) and voltage
is 2.28V, 2.36V, which is normal; test pin 1,2 of Xs301 and voltage is also normal; check nerve flat cable
and contact is good, so we judge that laser head focus winding has been burnt down, after changing
loader, trouble is removed.
[ Example 7] Symptom: AV output has no colour
Description: when in AV output, there is only black and white picture output without colour, other
video port output also has abnormality.
Analysis and troubleshooting: test other port output and there is still no colour, which means that
trouble should lie in decode circuit; check decode chip and each voltage is normal; according to circuit
working principle, this trouble often appear due to the influence of clock frequency; use electric iron to
heat 27M crystal oscillograph and find that picture has flickering and colour appears sometimes; after
changing 27M crystal oscillograph, trouble is removed.
[ Example 8] Symptom: not read CD disc
Description: can play DVD disc and MP3 disc, not read CD disc
Analysis and troubleshooting: check laser head, focus, feed, main axis and trace and they are
normal, test Q302 emitter electrode voltage and it is on low side, which should be 3.1V in normal
conditions, so we doubt that R302 resistor has been damaged, use multimeter to test the resistance
value and it is infinite, after changing resistor, trouble is removed.

3.5.9 function introduction to VIPER22A
1. DESCRIPTION
The VIPer22A combines a dedicated current mode PWM controller with a high voltage Power MOSFET
on the same silicon chip. Typical applications cover off line power supplies for battery charger adapters,
standby power supplies for TV or monitors, auxiliary supplies for motor control, etc. The internal control circuit
offers the following benefits:
- 73 -
– Large input voltage range on the VDD pin accommodates changes in auxiliary supply voltage. This
feature is well adapted to battery charger adapter configurations.
– Automatic burst mode in low load condition.
– Overvoltage protection in hiccup mode.
2. FEATURES
◆ FIXED 60 KHZ SWITCHING FREQUENCY
◆ 9V TO 38V WIDE RANGE VDD VOLTAGE
◆ CURRENT MODE CONTROL
◆ AUXILIARY UNDERVOLTAGE LOCKOUT WITH HYSTERESIS
◆ HIGH VOLTAGE START UP CURRENT SOURCE
◆ OVERTEMPERATURE, OVERCURRENT AND OVERVOLTAGE PROTECTION WITH
AUTORESTART

3.5.10 function introduction to HS817
U502 (HS817) is a photoelectric coupler, shown as the figure 3.5.10.1. 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.

3.5.11 function introduction to LM431A
U503 (LM431A) is a 2.5V comparator, shown as the figure 3.5.11.1. Compared the inputted voltage
of 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.

Chapter Four
Disassembly and Assembly Process
DVD players manufactured in BBK are largely identical but with minor differences and are mainly
composed of loader components, control panel components, decode and servo board components,
power board components, power amplifier board components, MIC board components and AV board
components. In order to speed up the compilation of “Service Manual”, we shall not give repeat
explanation to model with minor differences in chapter four “Disassembly and Assembly Process” for the
later compiled service manuals. For disassembly and assembly process in this chapter, please refer to
chapter 4 of “DK1005S Service Manual” or “DK1020S Service” .
The pictures of this model are shown as follows:
