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.

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.

2.3.12 Channel delay set-upSet-up of time delay in the surround
channel
Usually, time delay in the Dolby digital
decoding system is preset to ensure best effect
while installing the Home Theater. However, in
case you wish to adjust your system more
precisely, please consult instructions given in
this manual.
- 11 -
Set up of tie delay for this device is possible
in both Dolby Digital and Dolby Pro Logic modes..
To set the desired delay you have to know
the distance from the place where you are, to the
front speakers and Surround speakers as shown
in Fig.1. Consult Fig.2(Dolby Pro Logic mode)
and 3(Dolby Digital mode)in order to determine
the distance to Surround speakers(axis Y in the
figure)and the distance to the front speakers
(axis X in the figure). Crossing point of those two
lines on the chart will give the recommended
delay value.
Set-up of time delay in the central channel
Sometimes several people are listening to
the music, and the space is limited. In this case,
you can install three speakers(two front ones
and a central one)as shown in Fig.1 with the
distance to the listener being approximately the
same. The central channel delay is to be set at
“0”.
Should the central speaker be in close
proximity to left and right front speakers as
shown in Fig.2, or the central speaker be nearer
to listeners when compared with front speakers’
location, or the central speaker be nearer to the
listener by 1 foot, in all these cases you may set
the delay value for the central channel at 1 ms.
For instance, as shown in Fig.2, if the line C
is by 1 foot shorter than the lines R and L, the
delay value is to be set at 1 ms. If your sofa is
broad enough, and there are several listeners
sittings on it.
“Night” mode
The Dolby Digital system provides an
extremely broad dynamic range of playback
sound-from gentle to roaring. It creates the
presence effect, especially while seeing motion
pictures. However, at night a powerful sound
with a broad dynamic range may give pleasure to
you, but disturb and annoy your family and
neighbors. If you just decrease the volume, you
will immediately notice that you ceased to hear,
e.g., Dialogues as clear as you do at normal
volume, and such sound effects as rustle,
whisper etc have merely disappeared. To avoid
this, you just have to decrease the volume of
“loud”sounds by simultaneously increasing the
volume of “soft”sounds with the volume of
“average”sounds left unchanged, i.e.just
decrease the dynamic range of sound
accompaniment. Only Dolby Digital system
provides for such a method of sound control. It
uses the principle of compressing the acoustic
signal’s dynamic range while recording;
therefore, while playing an inverse
transformation(volume expansion)takes place.
This is called”night”mode. The regulation limits
are restricted, however, to avoid distortions of
resultant signal.
It makes sense to locate the speakers in
one line, as shown in Fig.3 with the delay value
of the central channel to be set at “0”. Finally, if it
will be necessary to install the central speaker
behind the left and right front speakers, the delay
value shall be set at “0”.

Note: 1. When reading DVD, there are only A, B, C, D signals.
2. When reading CD, there are A, B, C, D, E, F signals.
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: wave length of loader DVD laser diode is 650nm, wave length of CD laser diode is
790nm, the wave length which is within 370nm and 750nm is visible light, the laser in the course of
reading DVD disc is visible light, and that when reading CD disc is infrared light.
(2) Principle about laser head picks up signal: laser beam projects onto disc, when laser beam focus
projects onto disc vertically, laser beam will produce reflection, reach on light sensor through reflection
loop and converse into electronic signal through photoelectric cell. For the reflection loop produced in
non pit information area and pit information area in disc has difference and reflects into different position
of light sensor, photoelectric diode in different positions on light sensor will produce different signals to
process all signals on light sensor and then produce digital signals.
(3) Focus, trace coil: when laser head is reading signals normally, information side should be in the
focus of laser beam, because of factors of disc error, high speed rotation and machine error, it is
unavoidable that laser beam focus deviates from information face to produce phenomena of orbit boas
and refocusing. Focus , trace coil is added on loader to adjust laser beam to make it correctly focus in
information area.
(4) Formation of RF signal: when disc reading is normal, light sensor will have 160MV, vague and
eye pattern waveform which is added on A, B, C, D respectively, and output RF signal from FRO pin after
being overlapped by adder inside light sensor, the frequency when reading DVD disc is much higher
than that when reading CD disc, output amplitude is about 1.4V.

3.2.2 Servo circuit
1. DK1910S 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, shown as the figure 3.2.3.1:
2. Working principle: after powering on or disc in, according to IOA signal, disc identification circuit
decides through which path of variable resistor the laser detecting diode gets path to the ground,
meanwhile MT1389 decides whether DVD laser or VCD laser is emitted according to IOA signal, which
can be fulfilled through laser power control circuit. When IOA is high level (3.3V), Mt1389 pulls LOD1 of
V302 base electrode in laser tube power control connected to VCD down to about 2.2V to make V302 on
and to make VCD laser tube emit beam; then decides whether to pull up or pull down LOD1 according to
voltage after the feedback from MDI1 to control the power of light emission diode. Similarly, when IOA is
low level (0V), MT1389 pulls LOD2 of V301 base electrode in laser tube power control connected to
- 20 -
DVD down to about 2.2V to make V301 on and to make DVD laser tube emit beam; then decides
whether to pull up or down LOD2 according to the voltage after the feedback from MDIAfter 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
- 21 -
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 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.

3.2.3 Main axis braking control circuit
1. Main axis braking control circuit is shown as the following figure 3.2.3.1:
Figure 3.2.3.1 Main axis braking control circuit diagram
Internal processing50
The equivalent circuit is shown as the following figure 3.2.3.2:
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.
Figure 3.2.3.2 Main axis braking control equivalent circuit diagram
- 23 -
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 R319, R320 and pin 35, 36 of
MT1389 after being processed inside MT1389 and magnified, then sends to pin 50 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.

3.2.4 Disc identification circuit
1. Disc identification circuit is shown as the following figure 3.2.4.1:
Loader
Figure 3.2.4.1 Disc identification circuit diagram
- 24 -
2. Working principle: the function of disc identification circuit is to identify the disc inserted to loader
and judge whether the disc is VCD or DVD to perform the corresponding control acts. When disc is
inserted in, decode servo control IC MT1389 defaults disc to DVD. Pin 112 of MT1389 outputs a low
voltage signal, V305 and V304 are cut off, V303 is on, laser receiver tube inside loader selects DVD
channel, now IOA is low level input loader to make loader in the state of reading DVD, through detecting
laser power feedback signal, MT1389 analyses whether the preliminary judgment is correct (disc is
defaulted DVD). When detecting correct preliminary judgment, loader runs in the state of reading DVD;
when detecting incorrect preliminary judgment, MT1389 outputs a high voltage signal from its pin 112,
V305 and V304 are on, V303 is cut off, laser receiver tube inside loader selects VCD channel, now IOA
is high level input loader to make loader in the state of reading VCD. Whether the preliminarily defaulted
disc is VCD or DVD is set by MT1389 internal software.
Note: V303 and V304 are MOS tube.

When not opening disc tray, pin 54 and 39 of MT1389 are low level. When opening disc tray, pin 54
of MT1389 sends a high level; V308 is on; V308 collector electrode changes into low level; LOAD-
changes into low level; V306 base electrode changes into low level; V306 is on. V306 collector electrode
changes into high level and LOAD+ changes into high level.

When closing disc tray, pin 39 of MT1389 sends a high level; V307 is on; collector electrode
changes into low level; LOAD+ is low level; base electrode through R324 and V309 is low level; V309 is
on; V309 collector electrode changes into high level; LOAD- changes into high level.
The function of V310 is interlock TRCLOSE and TROPEN signal to ensure the two are not high level
at the same time. When the two are high level input, base electrode of V308 is made to low level through
V310 on to ensure the normal working of disc in/out circuit. The function of electrolytic capacitor TC309
and Tc308 is to avoid the sudden change of the voltage on two ends of disc in/out electric machine to
make disc in/out acts smooth.

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 MT1389 FLASH, TAS5508 and
Cs5340. 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. In the course of system working, pin 214 of MT1389 outputs reset
signal to reset TAS5508 and CS5340 on power amplifier board.

In normal times, it is kept in high level, but after pressing MUTE button, MUTE signal changes to low
level to control TAS5508 and make it not output sound.
The other factor that causes mute in this model is that after inserting headphone, power amplifier
board has no output. As shown in figure 3.2.7.2, this player has two HDET signals, in which one is
outputted from headphone terminal and sent to Mt1389, and the other is sent to TAS5508 after Mt1389
receives HDET signal outputted from headphone. When headphone is not inserted, HDET signal
outputted from headphone keeps in high level, after headphone being inserted, it changes into 0V and
transmits to pin 184 of U201 (MT1389). Pin 174 of MT1389 also outputs RDSID signal, and signal name
changes into HDET through flat cable XS201. In normal times, it is also high level, after U201 (MT1389)
receives HDET outputted from headphone, it changes into low level, and HDET signal outputted from
headphone also changes from high level into low level to inform N12 (TAS5508) of mute. MUTE, HDET
signal change is shown as the following figure:

Note: when inserting headphone, only mixed left/right channel on AV board have output, and audio
signal on power amplifier board has no output; when in mute state, all have no output.

2. Working principle:Brightness signal, colour difference signal, CVBS signal and component video
signal after being decoded by U201 (MT1389) are sent out to the corresponding terminal for output after
lowpass filtering and clipping. Take Y1 signal as an instance, the following figure 3.2.8.2 shows the
working principle of filtering limiter circuit.
This circuit is very simple. R261 is a matched resistor, which makes the signal achieve the
maximum power on load. Capacitor C106, C108 and inductor L106 compose a lowpass filter which
filters the high frequency interference signals beside useful ones; dual diode VD102 is clamping circuit.
It is known from features of diode that the maximum amplitude of colour difference signal Y 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.

1. Audio power amplifying circuit block diagram is shown as the following figure 3.2.9.1:
Figure 3.2.9.1 Audio power amplifying circuit block diaghram
2. Working principle:
N5 (CD4052): CD4052 is a switch for selection, which is used to select externally inputted tuning
signal, MIC signal and left/right channel audio signal. When the player is in the state of playing disc, MIC
signal may be on. MIC changes to digital signal after conversion of CS5340, and this digital signal
outputs from pin 227 of MT1389 (ASDATO) to power amplifier board after outputting to decode for
processing. Note: MIC signal through Cs5340 does not pass through N4 (74HCT125).
N7 (CS5340): converse analog signal sent out from CD4052 to digital signal for processing by back
stage circuit.
N3, N4 (74HCT125): 74HCT125 is a gating IC with 4 paths in it, which can perform gating to 4 paths
signals. N3 performs gating to MCLK, audio signal SDATA0, SDATA1 and SDATA2.
N12 (TAS5508): after the processing of pulse width demodulation to SDA, SDATA0, SDATA1,
SDATA2 digital audio signals, 10 channel outputs generate, that is, left/right channel output on
input/output board, headphone left/right channel output, front left/right channel on power amplifier board,
surround left/right channel output, subwoofer channel and centre channel output.
N13, N14 (TAS5112): is a high performance amplifying IC, which demodulates and amplifies front
left/right channel, surround left/right channel, centre and subwoofer after PWM of N12 (TAS5508).
3.2.10 Input/output circuit
Input/output circuit is also called AV board. AV board outputs video and audio signals sent from
decode board and power amplifier board from the corresponding terminal after coupling and filter circuit
processing. Externally inputted audio signal is sent to power amplifier board and decode board for
processing also through AV board. Circuit includes composite video output terminal, S-video terminal

1. SCART terminal
SCART is a terminal that integrates video and audio together, which can transmit video and audio
signals at the same time and operation is very convenient. It has 21 pins in all and lies in the middle part
at rear side of the player. Pin function is shown as the following table:
PDATO PDAT1 PDAT2 pin 8 of SCART terminal Function
0 ___ 0 10V AV4:3()
0 ___ 1 7.5V AV16:9
1 ___ 0 0.90V TV
1 ___ 1 0.85V TV
- 30 -
Note: PDAT0 and PDAT2 are used to control the input voltage on pin 8 of SCART terminal. PDAT1
is used to control the voltage change on pin 16 of SCART terminal. The voltage on pin 16 controls and
decides SCART selects whether RGB or CVBS mode.
3.2.11 Control panel components
1. Control panel components block diagram is shown as the following figure 3.2.11.1:
___ 0 ___ ___ CVBS MODE
___ 1 ___ ___ RGB MODE
2. Working principle: panel is mainly composed of VFD screen, drive chip Ad7312, remote controller
IR receiver, digital potentiometer, MIC jack, button and indicator light.
VFD is a vacuum fluorescence display screen and the working principle is the same with that of
CRT TV set, that is, emit light and display through electron bombarding fluorescent powder. Pin 1, 2, 34
and 35 of VFD are filament power supply pin, GRID1GRID8 is segment control equal to grid, which
speeds up electro emission and is responsible for display selection within reticular scope in display
screen. SEG1SEG16 is bit control connected to single character with fluorescent powder on it. When
electro is bombarding it, it emits light and displays character or strokes.
The function of N101 (Ad7312) is to drive display to display the corresponding state after
processing data signal sent from decode board, meanwhile scan panel buttons matrix and sends it to
CPU in digital signal means after processing button information to control the player and perform the
corresponding acts.
Pin 3 of remote control IR receiver is 5V power supply pin, pin 2 grounds, and pin 1 is output pin.
After processing remote controller buttons information, remote control receiver outputs from pin 1 and
then sends to decode board directly.
Digital potentiometer is used to adjust volume, which uses the phase difference of pulse send out
from pin 1 and 3 of it to realize the adjustment of volume.

Figure 3.2.12.1 Power supply circuit block diagram
2. Working principle: this power supply circuit is composed of two parts that use electromagnetic
disturbance filter circuit, bridge rectification circuit and other module circuit commonly. The first part
circuit generates P+28V DC voltage used for power amplifier circuit power supply; the other part is
responsible for power supply of other module circuit of this player. Working principle of each composed
part is shown as follows:
(1) Electromagnetic disturbance filter circuit: for various electromagnetic radiation exist outside, the
input AC will be affected. The function of electromagnetic disturbance filter capacitor is to filter these
disturbance to make those that enter bridge rectification circuit are pure 220V AC.
(2) Bridge rectification and filter circuit: the function of this circuit is to generate a 310V DC to supply
usage for back stage circuit.
- 32 -
(3) Start circuit: when power on and transformer has not started to work, start circuit provides a
power supply voltage for switch module to make it work. When transformer begins to work, the voltage
provided by power supply circuit for switch module is used to maintenance the working of switch module.
(4) Absorption loop: switch module performs on/off action in a very high frequency, so a very strong
self induction voltage in the preliminary coil of transformer, which may probably cause the damage of
switching module. The function of absorption is to form a loop for this self induction to ensure the normal
working of circuit.
5) Switch module: the input from transformer is 310V DC. To make transformer work, AC shape
voltage must be presented. The function of switch module is to control this 310V DC to make it on for a
while and off for another while to make the input terminal of transformer generate high and low change,
thus the transformer can work.
(6) Power supply circuit: provides a power supply voltage for switch module.
(7) Rectification diode: the voltage outputted from transformer just now is pulse DC. The function of
rectification diode is to change pulse DC into DC together with the back filter circuit.
(8) Feedback loop: the time length of “on” and “off” inside switch module 5L0380R is decided bu
feedback loop. Feedback loop samples +3.3V output voltage; when output voltage is too high, voltage
sampled is on high side, through feedback loop, the space occupation ration of pin 5 of 5L0380R is
changed, “on” time decreases and output voltage begins to reduce; when output voltage is too low,
voltage sampled is on low side, through feedback loop, the space occupation ratio of 5L0380R increases,
and 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 over 2.5V (that is output voltage is high), 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;
the light emission is stronger, the degree of “on” is stronger, “on” time of switch module 5L0380R
decreases, output voltage begins to decrease; when sampling voltage is less than 2.5V (that is, output
voltage is low), LM431 cuts off, “on” time of VEPR22 increases, output voltage increases, thus, through
the auto control function of feedback loop, power board outputs stable voltage.
(9) Filter circuit: the function of it is to generate a stable and small ripple DC voltage. “ " filter is
mostly used in filter circuit. The feature of capacitor filtering is that when load resistance is high and
current is small, the filtering is obvious; for inductor filtering, when load resistance is small and current is
big, filtering is obvious. Form capacitor to “ “ filter and it can exert better filtering effect.
3. Main function of each output voltage of power board:
(1) FL+, FL-: supply power for filament of panel display screen.
(2) D+5V: supply power for N101, servo drive chip U302 (D5954) and open/close door circuit.
(3) P+28V: supply power for audio power amplifying chip N13, N14 (TAS5112).
- 33 -
(4) A-10V, A+10V: supply power for audio power amplifying chip N1 (F4558) on power amplifier
board. A+12V: supply power for tuning data processing chip N6 (SAA6558) and tuner.
(5) D+3V3: supply power for U201 (MT1389), U214 (FLASH), U211 (SDRAM) and U205 (74HCU04).
(6) A+5V (XP203 pin 5): supply power for loader.
(7) A+5V (XS504 pin 1): supply power for power amplifier board A/D conversion chip N7 (CS5340),
digital audio pulse width modulating chip N12 (TAS5508), power amplifier board data selection chip N5
(CD4052), audio power amplifying chip N8 and N9 (TLV272).

on.
Analysis and troubleshooting: test power board 5V, 3.3V voltage and they are both normal, check
decode board 1389 chip power supply and it is 3.3V, 1.8V, which is normal; then use oscillograph to
check the crystal oscillator that provides 1389 chip with 27MHZ clock frequency; check oscillation
frequency and this frequency is on lower side, so we doubt that the crystal oscillator has trouble; after
changing it, trouble is removed.

find that V301 emitter electrode has no 3.3V power; check 3.3V power of the player and it is normal;
seeing from circuit diagram, 3.3V is added to V301 emitter electrode through R301, so we doubt that the
trouble is caused by R301; use resistance level (2K) of multimeter to test and find that resistance value
is infinite; after changing it, V301 emitter electrode is 3.3V, which is normal, laser head emits DVD laser
light normally, and trouble is removed.
Example 3 Symptom: front power amplifier has no sound output

may judge that IC power supply is normal; use oscillograph to test whether vertical screen-shielded
filtering inductor L2, L3 have waveform and find there is no waveform output, so we judge that power
amplifier IC N14 may be invalid; after changing N14, trouble is removed.
- 35 -
Example 4 Symptom: waveform is small
Description: left and right output waveform of mixed audio terminal are both small
Analysis and troubleshooting: left and right output waveform of mixed audio terminal are both small,
when this situation appears, the possibility for the element commonly used by two branch terminals is
large. Firstly check whether the flat cable between AV board and power amplifier board is well connected
or disconnected, after removing the above factor, check power supply on IC with location number N8, N9
on power amplifier board and they are both +5V, N12 power supply is 3.3V, which is normal; check flat
cable between power amplifier board and decode board and it is also normal; check audio signal AD
conversion voltage ADACVDD3 and it is 2.4V, which is slightly small, which should be 3.3V in normal
conditions; check and find that resistance on two ends of C235, C231 are infinite, so seeing from this,
L207 has damaged; after changing it, trouble is removed.
Example 5 Symptom: headphone has no sound
Description: after inserting headphone, two sides of headphone have no sound
Analysis and troubleshooting: after inserting headphone, test voltage of pin 8 on pow amplifier
board X104 and it is 0, which is normal; test pin 8 voltage of N11, N8, N9 and it is +5V, which is also
normal; then check pin 36 of N12 and voltage is 0, this pin is IC power supply pin and it should be 3.3V
in normal conditions; use multimeter to test R113 resistance and it is infinite, this resistor has trouble;
after changing it, trouble is removed.
Example 6 Symptom: tuning has no sound
Description: when tuning, connect left channel of power amplifier and there is no sound output.
Analysis and troubleshooting: adjust in tuning state firstly, use probe of oscillograph to test pin 3, 13
of N15 and find that there is audio signals; then test pin 4 of N7 and there is no audio signals; but test pin
10, 12 and there is audio signals. Observe and find that N7 is invalid; after changing N7, trouble is
removed.
Example7 Symptom: the player not power on
Description: connect with power, blue power indicator light is on, red standby indicator light also
emits light; press POWER button on the panel and the player cannot start up, red indicator light will not
flash and is in standby state all the time.
Analysis and troubleshooting: check STBY signal at the moment of power on according to symptom
and there will be a pulse without abnormality; seeing from this, tis trouble should lie in standby control
circuit of panel; check CPU5V power voltage and it is normal; when pressing POWER button to switch
on the player, check STBY signal from decode board to power board and there is no change; check
power light touch switch and it is not damaged; test pin 39 of panel IC6317, after pressing POWER

is disconnected, after changing it, trouble is removed.
Example 9 Symptom: remote control has no function
Description: when pressing remote controller, there is not any function.
Analysis and troubleshooting: insert probe of oscillograph into pin 12 of decode board XP900; when
pressing remote controller, there is not any response on oscillograph, which means remote control
signals are not received; check L233, R230 and find that there is no disconnection and joint welding;
contact probe with pin 1 of N102 receiver on main panel, press remote controller and there is signal
skipping, which means receiver has no trouble; then connect to pin 2 of N101, press remote controller
and there is no signal skipping on oscillograph; carefully observe and find that R110 has rosin joint; after
welding again, trouble is removed.
Example 10 Symptom: power amplifier has no sound
Description: line output sound is normal, when switching to tuning state, there is no sound output;
after power on of this player, switch on power amplifier volume, power amplifier output has small noise.
Analysis and troubleshooting: the symptom has indicated that trouble lies in the common channel
around power amplifier; check SD signal of power amplifier IC and it is 0V all the time, now power
amplifier IC has been in over-current or over-heat protection state; use multimeter to test voltage to
ground of each lead wire of power amplifier output end and find that voltage to ground of subwoofer
channel are 9V and 5V (14.5V in normal conditions); take down L10 of this channel and test, sound
restores to be normal, so we confirm that trouble is caused by L10, after changing it, trouble is removed.

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.

13. Waveform diagram of the comparison between LRSWM signal (channel 1) and LRSWMUT
signal (channel 2). When turning on mute, 1389 sends out low level signal LRSWMUT more than 310ms
to make LRSWM signal level pull down and output mute. 1389 is muted from inside to make all channels
have no output. Mute means of centre/surround channel is the same with that of main channel.

Section Five Function Introduction to IC
3.5.1 Function introduction to MT1389HD 1. Description
MT1389HD (U201) is a cost-effective DVD system-on-chip (SOC) which incorporates advanced features
like MPEG-4 video decoder, high quality TV encoder and state-of-art de-interlace processing.
Based on MediaTek’s world-leading DVD player SOC architecture, the MT1389E is the 3rd generation of
the DVD player SOC. It integrates the MediaTek 2nd generation front-end analog RF amplifier and the
Servo/MPEG AV decoder.
To enrich the feature of DVD player, the MT1389 equips a simplified MPEG-4 advanced simple profile
(ASP) video decoder to fully support the DivX1 Home Theater profile. It makes the MT1389-based DVD
player be capable of playback MPEG-4 content which become more and more popular.
The progressive scan of the MT1389HD utilized advanced motion-adaptive de-interlace algorithm to
achieve the best movie/video playback. It also supports a 3:2 pull down algorithm to give the best film effect.

3.5.11 function introduction to CD4052 1. Description
The CD4052B (N5) analog multiplexers is digitally-controlled analog switches having low ON impedance
and very low OFF leakage current. Control of analog signals up to 20VP-P can be achieved by digital signal
amplitudes of 4.5V to 20V (if VDD-VSS = 3V, a VDD-VEE of up to 13V can be controlled; for VDD-VEE level
differences above 13V, a VDD-VSS of at least 4.5V is required). For example, if VDD = +4.5V, VSS = 0V, and
VEE = -13.5V, analog signals from -13.5V to +4.5V can be controlled by digital inputs of 0V to 5V. These
multiplexer circuits dissipate extremely low quiescent power over the full VDD-VSS and VDD-VEE
supply-voltage ranges, independent of the logic state of the control signals. When a logic “1” is present at the
inhibit input terminal, all channels are off.
The CD4052B is a differential 4-Channel multiplexer having two binary control inputs, A and B, and an
inhibit input. The two binary input signals select 1 of 4 pairs of channels to be turned on and connect the
analog inputs to the outputs.

3.5.12 function introduction to SAA6588 1. DESCRIPTION Today most FM radio stations in Europe and meanwhile also many FM/AM radio broadcasting stations in
the USA transmit the inaudible European RDS (Radio Data System) or the USA RBDS (Radio Broadcast
Data System) informations respectively. Likewise nowadays receivers, most car radios and also some home
and portable radios on the market include at least some of the RDS features.
The RDS/RBDS system offers a large range of applications by its many functions to be implemented. For
car radios the most important are:
◆ Program Service (PS) name
◆ Traffic Program (TP) identification
◆ Traffic Announcement (TA) signal
◆ Alternative Frequency (AF) list
◆ Program Identification (PI)
◆ Enhanced Other Networks (EON) information.
The RDS/RBDS pre-processor is a CMOS device that integrates all RDS/RBDS relevant functions in one
chip. The IC contains filtering and demodulation of the RDS/RBDS signal, symbol decoding, block
synchronization, error detection, error correction and additional detectors for multi-path, signal quality and
audio signal pauses. The pre-processed RDS/RBDS information is available via the I2C-bus.
The RDS/RBDS pre-processor replaces a number of Ics and peripheral components used nowadays in
car radio concepts with RDS or RBDS features. The integration of the relevant RDS/RBDS data processing
functions provides, in an economic manner, high performance of RDS/RBDS processing and reduces the
real-time requirements for the main radio microcontroller considerably. In addition it simplifies the
development of the RDS specific software for the main controller of the radio set.
- 73 -
Compared with standard radio systems, RDS/RBDS controlled radio systems additionally require an
RDS/RBDS demodulator with a 57 kHz band-pass filter, information about the current reception situation
(reception quality, multi-path disturbance etc.), and additional microcontroller power for RDS/RBDS data
processing, decoding and radio control.
The new RDS/RBDS pre-processor includes all these specific functions and meets all requirements of a
high end RDS/RBDS radio. Moreover the timing requirements of the set controller, regarding RDS/RBDS data
processing are reduced due to the integration of decoder functions, so that the development of radio control
software can be concentrated specifically on radio set features.
2. FEATURES
◆ Integrated switched capacitor filters
◆ Demodulation of the European Radio Data System (RDS) or the USA Radio Broadcast Data System
(RBDS) signal
◆ RDS and RBDS block detection

seamlessly with most audio digital signal processors. In crystal mode, the TAS5508 automatically adjusts
control configurations in response to clock and data rate changes and idle conditions. This enables the
TAS5508 to provide an easy to use control interface with relaxed timing requirements.
The TAS5508 can drive eight channels of H-bridge power stages. Texas Instruments H-bridge parts
TAS5111, TAS5112, or TAS5182 + FETs are designed to work seamlessly with the TAS5508. The TAS5508
supports both single-ended or bridge tied load configurations. The TAS5508 also provides a high
performance differential output to drive an external differential input analog headphone amplifier (such as the
TPA112).
The TAS5508’s uses an AD modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz
data. The 8x over sampling combined with the 5th order noise shaper provides a broad flat noise floor and
excellent dynamic range from 20 Hz to 20 kHz.
The TAS5508 is clock slave only device. The TAS5508 receives MCLK, SCLK and LRCLK from other
system components. The TAS5508 accepts master clock rates of 64, 128, 192, 256, 384, 512, and 768 Fs.
The TAS5508 accepts a 64-Fs bit clock.
The TAS5508 allows for extending the dynamic range by providing a power supply volume control (PSVC)
output signal.

3.5.20 Function introduction to HS817 HS817 (U502, U506) is a photoelectric coupler, shown as the figure 3.5.20.1. 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,
- 85 -
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.

3.5.21 Function introduction to TL431A TL431A (U503, U507) is a 2.5V comparator, shown as the figure 3.5.21.1. 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.
