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.

2.4.12 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. Set up of time 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, of 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 you sofa is
broad enough, and there are several listeners
sitting on it, 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”.
2.4.13 “Night” mode
He 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.
- 11 -
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.

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 MT1389E 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), Mt1389E pulls LOD1 of
Q302 base electrode in laser tube power control connected to VCD down to about 2.2V to make Q302
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), MT1389E pulls LOD2 of Q301 base electrode in laser tube power control connected to
DVD down to about 2.2V to make Q301 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 MDI1.
After loader reading disc information, A, B, C, D, E, F signals are sent out to Mt1389E (DVD only
has A, B, C, D signals), and then inputted from pin 2~11, 18, 19 of MT1389E. After being amplified and
processed by the pre-amplifier inside MT1389E, now signals are separated to two part s for processing
inside Mt1389E.
After being processed by digital servo signal circuit inside MT1389E, 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 MT1389E respectively, then change into analog servo control signal
FOSO, TRSO, DMSO, FMSO through integration circuit composed by resistor capacitor, and send to
driver circuit D5954 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 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 MT1389E, 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 MT1389E, 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 MT1389E, 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 to MT1389E, in usual conditions, TROPEN and TRCLOSE sent out by pin 39,
99 of Mt1389E are both low level, when signal of “open” comes, after Mt1389E 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, MT1389E pulls
- 20 -
down TRCLOSE and open/close electric machine stop running. When MT1389E receiving “close” signal,
TROPEN is set high level by MT1389E, 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, MT1389E pulls down TROPEN and electric
machine stops running to finish “close” process.
3. Explanation to servo terms
(1) FOO: for disc make differences, and 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,
now focus point of objective lens is required to adjust to make focus aim at data pit exactly. The acts are
mainly to make objective lens move upwards and downwards.
(2) TRO: data information is saved in disc in form of tracks. When disc is rotating, disc deviation will
produce, now laser head is required to adjust. In this process, objective lens makes forward and
backward movement with small moving range.
(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 track.
(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.

3.2.3 Mute circuit
DK1110SI mute control circuit includes power-on mute control, power-off mute control and usual
mute function.
1. Power-on mute is shown in the figure 3.2.3.1. When voltage of pin 5, 10 of power IC TDA8947 is
lower than power supply voltage 3.5V of this IC, this IC enters MUTE mode, from 0 to 0.8V, it is STANBY
mode.
When power on, due to the function of Tc147 charge, V102 cuts off at the beginning, V103 is on,
HERDM is low level, shown in the figure 3.2.3.2. Seen from the figure, when HARDM is low, SCM,
LRSWM are pulled down to fulfil power-on mute.

3. Power-off mute: V100 realizes power-off mute function. When +12V power failure, Tc136 still
keeps high level, now base electrode of V100 is low, V100 is on, base electrode of V101, V104 gets high
level and they are on to realize power-off mute function.

2. Working principle:
Open door, VCC Q306CE electrode is on LOAD+ electric machine LOAD-
Q309CE electrode is on R326 ground
When action of opening door is not performed, pin 99 and 39 of MT1389E are low level. When
opening door, pin 99 of MT1389E send out a high level, Q309 is on, collector electrode of Q309 changes
to low level, LOAD- changes to low level, base electrode of Q306 changes to low level, Q306 is on,
collector electrode of Q306 changes to high level and LOAD+ changes to high level.
Close door: VCC Q307CE electrode is on LOAD- electric machine LOAD+ Q308CE
eklectrode is on R326 ground
When closing door, pin 39 of Mt1389 sends out a high level, Q308 is on, collector electrode
changes to low level, LOAD+ is low level, base electrode of Q307 changes to low level through R324,
Q307 is on, collector electrode of Q307 changes to high level, LOAD- changes to high level.
4. When inserting headphone, friction will produce noise, so these noise should be filtered. When
inserting, HDET pin is grounded and low level, which is sent to 188 pin of 1389E, 1389E receives HDET
low level and sends out control signal to TDA8947, output stops and mute function is realized.
Note: when inserting headphone, mixed left/right channel on AV board has output, audio signals on
power amplifier board have no output; when in mute, all has no output.

2. Working principle: when power on, voltage on two ends of capacitor Tc320 cannot change
suddenly, anode of capacitor begins charging from 0V, now triode Q320 is on, pin 5 of input end of phase
inverter U205C (HCU04) is high level, pin 6 of output end is low level and performs reset to chip
MT1389E, FLASH, TAS5508 and Cs5340; when capacitor charge is close to 3.3V, triode Q320 cuts off,
pin 5 of input end of phase inverter is low level, phase inverter outputs high level from pin 6 and system
reset finishes.
3. Key point voltage (unit: V) is shown in the following table:
The function of Q310 is to interlock TRCLOSE and TROPEN signals to ensure that the two are not
high level at the same time. When the two are high level input, the on of Q310 makes base electrode of
Q309 be low level to ensure the normal working of open/clode door circuit, electrolyte capacitor TC306
and TC305 are used to prevent the sudden change of two ends of in/out control electric machine and
make the action gentle.

2. In order to prolong the usage life of electric machine and increase the influence of start-up
current to electric machine, when disc is in, R&D personnel design main axis electric machine into
running state all the time, even though STOP button is pressed. Thus, when pressing OPEN button, a
braking signal is required to make main axis electric machine stop rotating immediately to fulfill door
opening in short period.
During the course of playing, if OPEN button is pressed, main axis braking signal disappears, but
main axis electric machine is still in rotating state due to the function of inertia, now the inductive
electromotive force that produces from the rotation of electric machine achieves inductive voltage on

MT1389E internal D/A conversion and relevant processing, pin 37 of MT1389E outputs an instant
electric machine reverse braking signal to make main axis electric machine speed down, when

4. Working principle: panel is mainly composed of LED screen, drive chip Pt6961, remote control IR
receiver, digital potentiometer, MIC jack, button and indicator light.
The function of N100 (PT6961) is to process data signals sent from decode board to drive display
screen to display relevant state, and scan panel button matrix at the same time, after processing button
information, send to CPU in the means of digital signals to control the player and make it perform the
relevant action.
Pin 3 of remote control IR receiver HS0038A2 is 5V power supply pin, pin 2 is grounded, pin 1 is
output pin; remote control receiver processes button information of remote controller and then outputs
from pin 1 to decode board directly.

2. Working principle: brightness, chroma, CVBS and component video signals decoded by U201
(MT1389E), through low-pass filtering and clamping, are sent to the relevant terminal for output. Take Y
signal as instance, we will introduce working principle of clamping circuit, shown in the figure 3.2.9.2:
This circuit is very simple. R105 is a matched resistor to make signals achieve max power on load,
capacitor C106, C108 and inductor L106 compose a low-pass filter to filter high frequency interference
signals except for useful signals; diode VD108 and VD109 compose a clamping circuit, we know from
features of diode, the max range of chroma signal cannot exceed 5.7V, and cannot be lower than -0.7V
in minimum, thus the high voltage signals from TV set can be prevented from burning down the player.

3.2.10 Input/output circuit
Input/output circuit is often called AV board. AV board processes the video and audio signals sent
from decode board and power amplifier board through coupling and filtering circuit and then outputs
from the relevant terminal, externally-inputted audio signals are sent to power amplifier board and
decode board for processing through AV board. DK1110SI AV board video output (refer to 3.2.9 video
- 29 -
Circuit) circuit includes composite video output terminal, S-video and component video output terminal;
audio circuit includes mixed left/right channel output terminal, digital optical output terminal, coaxial
cable output terminal, SCART terminal and also one channel input terminal, that is left/right channel
input terminal.
1. SCART terminal
SCART is a terminal that integrates video and audio transmission into one. It may transmit video
and audio signals at the same time and it is very convenient for operation. It has 21 pins in all and
locates in the centre at rear side of the player. Pin function is shown in the following table:

2. Working principle
In power amplifier part, Karaoke processing circuit, external input circuit, headphone output circuit,
power amplifying circuit and mute circuit can be divided. Mute circuit has been introduced in section 2,
so here we will not say it again.
2-channel microphone input signals performs mixed amplification through an addition circuit
composed of operational amplifier N104 (F4558), through the clamping composed of VD122 and VD123,
prevents microphone inputting too large signals to damage rear stage circuit. Through preliminary
addition, amplified MIC signals enter an ADC conversion ship N108 (CS5340) which is controlled by I2S
signal; MO, M1 add pull-up resistor to 3.3V, select Clock Slave mode, output pin (pin 4) adds 10K
resistor to ground, select left align mode; MIC signals, after being processed by CS5340, change into
digital signals to input to 1389E, through 1389E internal processing, mix to left and tight channels for
output.
N111 (PT2314) is a selection switch, which selects left/right channel information of disc signal,
external input signal and tuning signals (external input and tuning only have left and right channels
signals input). In special mode, there is special sound output. PT2314 may process tweeter/bass and
volume adjustment. This player uses 3 of the channels, which are used as left/right channel information,
tuning signal, selection of external input signal and volume/tone adjustment. Through being selected by
PT2314, signals of left/right channel has 3 flow directions: one channel inputs power IC N106 (TDA8947),
one channel inputs to headphone amplifying chip RC4580, one channel inputs to pin 5 of N100 (F4558)
and mix with subwoofer.
Power IC N106 (TDA8947) is a 4-channel power amplifying IC, if single channel outputs, output
power range is from 1W to 25W; if all channels output, output power range is from 4W to 50W, in this
player, take channel 1 and 2 of N106 as the all channels output of subwoofer, rated output power is 15W;
take channel 3 and 4 as power output of lect and right channels, rated output power is 6W. The 3rd
channel is reverse output, so right channel output is reversely connected, its pin 5, 10 are mode
selection pin, this player uses them all together to make it as mute control pin.
RC4580is a dual-channel operational amplifier, as the amplifying output of headphone, its input is
directly connected with output signals of PT2314, after being amplified, output to the output socket of
headphone, mute control circuit is added on its output end.
Subwoofer output of this player is divided into two parts: one part is the subwoofer signals of
decode output to discs inside 1389E and the other part is mixed by left and right channel information
gated by PT2314. When in external input and tuning, without subwoofer signals outputted by 1389, now
all subwoofer is mixed from left and right channels. In subwoofer output channel, another chip M62429
is used. It is a 2-channel electric volume control IC and controlled by I2C signal; subwoofer signals
outputted from M62429, through first level buffer circuit, are sent to power IC for power amlifying,
similarly, in order to protect rear stage circuit, a clamping circuit is added. Power output of subwoofer is
fulfilled by the full connection of channel 1 and 2 of N106 (TDA8947).
- 32 -
Centre and surround power output is fulfilled by N110 (TDA8947). 1389E outputs analog audio
signals directly, after pre-amplifying and low-pass, outputted by N110 power amplifying. Similarly, the
3rd channel is reverse output, so centre is reversely connected to output. Its pin 5 and 10 are connected
together, as mute control pin.

2. Working principle: this power circuit is composed of two parts, with electromagnetic interference
filtering circuit and bridge rectification filtering circuit commonly used. The first part circuit produces
P+22V DC power and uses in power supply of power amplifier circuit; the other part is responsible for
power supply of other module circuit.
Working principle of each part is shown as follows:
(1)Electromagnetic interference filtering circuit: various electromagnetic radiation exits in
surroundings, the input AC power will be disturbed. The function of electromagnetic interference filtering
circuit is to filter these interference to make those that enters bridge rectification circuit is pure AC power.
- 33 -
(2) Bridge rectifying and filtering circuit: the function of this circuit is to produce a DC power about
310V to supply for rear stage.
(3) Start circuit: wen power on, transformer does not begin working, now start circuit provides switch
module with a power supply voltage to make it work, after transformer begins to work, the voltage
supplied by power supply circuit to switch module maintains the working of switch module.
(4) Absorption loop: switch module perform “on” and “off” action in very high frequency, so a strong
self-inductive voltage will produce in transformer primary winding to cause damage to switch module.
The function of absorption loop is to form loop for inductor to ensure normal working of circuit.
(5) Switch module: 310V DC power inputs from transformer. To make transformer work, AC shape
voltage must be shown. Function of switch module is to control this 310V DC power to make it on for a
whole and then off for a while to make a high/low level variation produce in input level of transformer,
thus transformer can work.
(6) Power supply circuit: provides switch module with a power supply voltage.
(7) Rectifying diode: voltage that outputs from transformer is pulse DC, the function of rectifying
diode is to change pulse DC into DC together with filtering circuit.
(8) Feedback loop: the time length of “on” of switch module is decided by feedback loop. Feedback
loop samples output level. When output voltage is too high, voltage sampled is on high side, through
feedback, to make the “on” time of switch module decrease, coupling of transformer reduces and output
voltage decreased. When output voltage is too low, voltage sampled is on low side, through feedback
loop, to make the “on” time of switch module increases, coupling of transformer increases and output
voltage increases, thus through auto control function of feedback loop, power board may output stable
voltage.
(9) Filtering circuit: the function is to produce a stable DC voltage with small ripple. “ "-type filter is
mostly adopted in filtering circuit. Features of capacitor filtering are that when load resistence 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. Constitute capacitor to “ "-type filter to get better filtering effect.
3. Main function of each voltage of power output board:
(1) +22V: output to power amplifier board and supply power for power amplifier circuit.
(3) D+5V: supply power for panel N100, servo drive chip U301 (D5954) and open/close door circuit.
(4) A-12V, A+12V: supply power for audio power amplifying ship N100 N104 (IC4558), N107
(RC4580) on power amplifier board.
(6) D+3V3 U201 (MT1389E), U207 (FLASH), U208 (SDRAM) and U205 (74HCU04) power supply.
(7) A+5V (pin 5 of XP203): supply power for loader.
(8) A+5V (pin 4 of XS504): supply power for power amplifier board A/D conversion chip N108
(Cs5340).

Section Three Servicing Cases
3.3.1 Servicing cases
[ Example 1] Symptom: not read disc
[ Example Symptom: waveform is small
[ Example Symptom: headphone has no sound
Description: not read any disc
Analysis and troubleshooting: check laser, light emission, feed, main axis, trace and they are all
normal, but there is no focus action; use multimeter to test pin 13, 14 of U301 (5954), voltage is normal
(about 1.4V); test pin 1, 2 of XS301 and voltage is normal; check nerve flat cable and contact is good, so
we judge that laser head focus winding is burnt down; after changing loader, trouble is removed.
Description: left and right output waveform of mixed audio terminal are small
Analysis and troubleshooting: left and right output waveform of mixed left and right audio terminal
are small, if this kind of case appears, the elements used by two terminals commonly are easier to have
trouble. Firstly check whether the flat cable between AV board and power amplifier board has well
contacted, after removing the above factors, then check power supply of IC with location number N101
on power amplifier board and they are +12V, -12V, which are normal; check flat cable between power
amplifier board and decode board and it is normal; check AD conversion voltage ADACVDD3 of audio
signals and find that it is 2.4V, which should be 3.3V in normal conditions; check and find that resistance
on two ends of C240, Tc210 is infinite, so we can confirm that L204 has trouble, after changing is,
trouble is removed.

Description: after power on, panel indicator light is not on
Analysis and troubleshooting: power on, use multimeter to test voltage of base electrode of V110
and it is 5V; test voltage on two ends of R110 and it is also 5V, thus only V100 has trouble, after
changing it, trouble is removed.
6]
Description: when reading disc or opening door, display on screen is not stable, and panel indicator
light flickers
Analysis and troubleshooting: when this kind of case appears, start from power supply. When
checking display screen 5V power supply, after no disc in or disc reading is normal, voltage keeps in
stable state, this voltage varies from 3.5 to 5.5V when reading discs, so the trouble should be caused by
power, voltage also varies the same when checking 5V output voltage of power board, check 5V voltage
filtering circuit elements and there is no abnormality, so we doubt that performance of the diode with
location number D510 is not stable, after changing it, trouble is removed.
7]
Description: when opening and closing door, speed is fast, disc reading is normal, picture and
sound output is normal.
Analysis and troubleshooting: when this trouble appears, trouble should lie in power circuit, check
power supply voltage of open/close door drive circuit and it increases to 7.5V; check voltage of other
circuit and it also increases, so trouble should lie in output voltage adjustment circuit; test voltage of IC
with location number U503 of power board and it is 3.3V; it is known from working principle of U503,
voltage of this pin is 2.5V when in normal conditions, change IC with location number U503, voltage
resumes to be normal and trouble is removed.

- 36 -
Picture output is normal; after playing for a period (about 5 minutes), picture has interference. To
analyse this trouble, firstly play DVD disc normally after power on, use electric iron to heat chip 1389,
picture has interference after heating; after changing chip 1389, trouble is remove.
9]
Description: after playing any disc for one hour, line and headphone sound output is normal, only
power amplifier channel has no sound output with slight noise; power on again after power off for a
period, the player resumes to be normal, after about 1 hour, there is no sound output again.
Analysis and troubleshooting: when this trouble appears, trouble lies in power amplifier output
circuit. Test power supply voltage of power amplifier IC TDA9847 and it is 23V, which is normal; use
oscillograph to test waveform of pin 6, 8, 9, 12 of TDA8947 and they are normal; it is known from
symptom, when there is no sound output, IC should lie on over-heat or over-current protection state; test
SCM control signal and there is no abnormality, so it means that trouble should be caused by power
amplifier IC itself; after changing TDA8947, trouble is removed.
10]
Description: when playing disc, player has no sound output, line and headphone have no sound
output; when rotate volume knob, panel display variation is normal, power amplifier output end has no
noise or current sound, disc playing is normal, after switching to tuning state, there is still sound output.
Analysis and troubleshooting: it is known from circuit principle, line, headphone and power amplifier
audio signal are the same signals , which are divided into three-channel signals through PT2314, so
trouble should lie in common channel. In addition, trouble should lie in surroundings of PT2314. Use
oscillograph to test TC145, TC146 location capacitor and there is no audio signal output, then test
TC141, TC132 location capacitor and waveform is normal, test N111 location IC power supply and SDA,
SCL signal and they are all normal; after changing PT2314IC, trouble is removed.

3.5.7 Function introduction to CD4094 1. DESCRIPTION
The CD4094BC (U213) consists of an 8-bit shift register and a 3-STATE 8-bit latch. Data is shifted
serially through the shift register on the positive transition of the clock. The output of the last stage (QS) can
be used to cascade several devices. Data on the QS output is transferred to a second output, Q'S, on the
following negative clock edge.
The output of each stage of the shift register feeds a latch, which latches data on the negative edge of the
STROBE input. When STROBE is HIGH, data propagates through the latch to 3-STATE output gates. These
gates are enabled when OUTPUT ENABLE is taken HIGH.

3.5.17 Function introduction to HS817 HS817 (U502, U506) is a photoelectric coupler, shown as the figure 3.5.17.1. 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.
Figure 3.5.17.1 2501 outside drawing
3.5.18 Function introduction to TL431A TL431A (U503, U507) is a 2.5V comparator, shown as the figure 3.5.18.1. 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.

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” .
