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

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.
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. 1Consult Fig.2(Dolby Pro Logic mode)
and3(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 in the figure).Crossing point of those two
lines on the chart will give the recommended
delay value.
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
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 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”.
Fig.1.Take into account the A-B distance; use both
figures for setting the desired time delay.

“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.

4.1 Servo Circuit
Servo system of this machine adopts SANYO loader and MTK decode scheme. And servo circuit is
mainly composed of front signal processing, digital servo processing, digital signal processing chip
MT1389 and driving chip AM5888. MT1389 is also main part of decode circuit. Block diagram of servo
circuit is shown in figure 4.1.1.

4.3 Video Circuit
MT1389L has video D/A converter circuit and video output has R/B/G, Y/Pb/Pr, Y/Cb/Cr, CVBS and
Y/C output modes, in which R/B/G, Y/Pb/Pr, Y/Cb/Cr and Y/C can not output at the same time and need
to be switched via software. CVBS is a separate output mode; four channel video signal is outputted to
AV board by MT1389 after video filtering and clamping. Block diagram of video signal process is shown
in figure 4.3.1.

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