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.

Section Five Function Introduction to IC

3.5.1 function introduction to MT1389E

1. DESCRIPTION

MT1389E 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 MT1389E 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.
The 108MHz/12-bit video DAC provides users a whole new viewing experience.

3.5.3 function introduction to HWD4863

1. DESCRIPTION

HWD4863 is a dual-bridge connecting audio power amplifier, which uses 5V voltage source and can
transmit 2.2W even continuous power to a 4Ω load (note1) or transmit 2.5W to a 3Ω load (note 2), THD+N
is less than 1.0%. In addition, when headphone plug is connected to jack, audio power amplifier is in signal
final end working mode to drive stereo headphone.

- 62 -

HWD4863 audio power amplifier is designed to provide high quality power output. It adopts surface
casing technology with minimum external components. To simplify audio system design, 4863 bridge
connecting speaker amplifying mode and single final end stereo headphone amplifying mode can be realized
by the same chip.

4863 adopts externally controlled low power cut off mode, stereo headphone amplifying mode and
internal thermal cut protection system, also utilizes features of circuit to decrease noise (click sound and
crepitating sound) and distortion degree.

S3C9454 is core part of charge part and a single chip. This single chip adopts 10-bit A/D conversion,

Discharge output pin, it is low when in normal condition and high

Bad battery or trouble control pin; when externally connected

tput high level control

this pin outputs wav with

circuit to achieve

(1) Single chip is with 10-bit A/D conversion with the precision 1/1024, the general negative voltage of
NI-MH is 3-6mv (6mv/1500mv=1/250) which can satisfy your requirements. Lithium battery precision may be
up to 5mv, and may be up to +/-20mv, that is 4.2V+/-0.02v when demodulation error is considered, and high
precision degree is obvious.

(2) Utilize PWM (Pulse width demodulator) of single chip itself to directly control DC/DC conversion.
Control method is provided by software to get different constant current and constant voltage curve (different
charge means may be designed according to client’s requirements), so the whole line is simple with low cost
and high security, power conversion efficiency is high and heat radiation is less.

(3) May well charge NI-MH, NI-CD, LI-ION battery. The way to judge whether it is fully charged: a. Max
voltage; b. max temperature increase; c. Negative voltage; d. Longest charge time. After battery is fully
charged and put again (within 15 minutes), it can be tested very quickly and stop charging (this is very
important to NIMH and NICD, which can prevent over charging and battery damage), may also use small
current to charge to recover the damaged battery when voltage is very low.
