Attention: This service manual is only for service personnel to take reference with. Before
servicing please read the following points carefully.
Safety precautions
1. Instructions
Be sure to switch off the power supply before replacing or welding any components or
inserting/plugging in connection wire. Anti static measures must be taken (throughout the entire
production process!):
a) Do not touch here and there by hand at will;
b) Be sure to use anti static electric iron;
c) It’s necessary for the welder to wear anti static gloves.
Please refer to the part list before replacing components that have special safety requirements.
Do not replace with different components with different specs and type at will.
2. LCD servicing precautions
2.1 Screens are different from one model to another and therefore not interchangeable. Be sure to
use the screen of the original model for replacement.
2.2 The operation voltage of LCD screen is 700-825V. Be sure to take proper measures in
protecting yourself and the machine when testing the system in the course of normal operation or
right after the power is switched off. Please do not touch the circuit or the metal part of the module
that is in operation mode. Relevant operation is possible only one minute after the power is
switched off.
2.3 Do not use any adapter that is not identical with the TV set. Otherwise it will cause fire or
damage to the set.
2.4 Never operate the set or do any installation work in bad environment such as wet bathroom,
laundry, kitchen, or nearby fire source, heating equipment and devices or exposure to sunlight etc.
Otherwise bad effect will result.
2.5 If any foreign substance such as water, liquid, metal slices or other matters happens to fall into
the module, be sure to cut the power off immediately and do not move anything on the module lest
it should cause fire or electric shock due to contact with the high voltage or short circuit.
2.6 Should there be smoke, abnormal smell or sound from the module, please shut the power off
at once. Likewise, if the screen is not working after the power is on or in the course of operation,
the power must be cut off immediately and no more operation is allowed under the same
condition.
2.7 Do not pull out or plug in the connection wire when the module is in operation or just after the
power is off because in this case relatively high voltage still remains in the capacitor of the driving
circuit. Please wait at least one minute before the pulling out or plugging in the connection wire.
2.8 When operating or installing LCD please don’t subject the LCD components to bending,
twisting or extrusion, collision lest mishap should result.
2.9 As most of the circuitry in LCD TV set is composed of CMOS integrated circuits, it’s necessary
to pay attention to anti statics. Before servicing LCD TV make sure to take anti static measure and
ensure full grounding for all the parts that have to be grounded.
2.10 There are lots of connection wires between parts behind the LCD screen. When servicing or
moving the set please take care not to touch or scratch them. Once they are damaged the screen
Page 4
would be unable to work and no way to get it repaired.
If the connection wires, connections or components fixed by the thermotropic glue need to
disengage when service, please soak the thermotropic glue into the alcohol and then pull them
out in case of dagmage.
2.11 Special care must be taken in transporting or handling it. Exquisite shock vibration may lead
to breakage of screen glass or damage to driving circuit. Therefore it must be packed in a strong
case before the transportation or handling.
2.12 For the storage make sure to put it in a place where the environment can be controlled so as
to prevent the temperature and humidity from exceeding the limits as specified in the manual. For
prolonged storage, it is necessary to house it in an anti-moisture bag and put them altogether in
one place. The ambient conditions are tabulated as follows:
Temperature Operation range 5 ~ +35 oC
Storage range -20 ~ +60 oC
Humidity Operation range 20% ~ 85%
Storage range 10% ~ 90%
2.13 Display of a fixed picture for a long time may cause a permanent after-image on the screen,
as commonly called “ghost shadow”. The degree of the after-image varies with the maker of LCD
screen. This phenomenon doesn’t represent failure. This “ghost shadow” may remain in the
picture for a period of time (several minutes). But when operating it please avoid displaying still
picture in high brightness for a long time.
3. Installation precautions
3.1 The front panel of LCD screen is made of glass. When installing it please make sure to put it in
place.
3.2 For service or installation it’s necessary to use specified screw lest it should damage the
screen.
3.3 Be sure to take anti dust measures. Any foreign substance that happens to fall down between
the screen and the glass will affect the receiving and viewing effect
3.4 When dismantling or mounting the protective partition plate that is used for anti vibration and
insulation please take care to keep it in intactness so as to avoid hidden trouble.
3.5 Be sure to protect the cabinet from damage or scratch during service, dismantling or
mounting.

1、 TUNER IC XC5200C
The Single-Chip Multi-Standard Tuner XC5200C supports all analog TV
formats transmitted worldwide in the 42-1000 MHz band on either cable or
terrestrial broadcast channels. It implements on-chip tuning, and channel
filtering without external (SAW) filters and has no manually tunable parts.
The broadband tuner converts the selected channel into an Intermediate
Frequency (IF), which is then sampled by an internal high-resolution
analog-to-digital converter (A/D) for further processing.
The IF signals are filtered using a standard-dependent high-rejection
channel filter and converted to a user programmable output frequency. At the
output of the D/A converter, the TV signal is low-pass filtered using a
high-performance smoothing filter and input to a variable gain amplifier. The IF
output amplifier gain can be controlled via an external analog signal on Vagc.
The XC5200C architecture is summarized in Figure 1. XC5200C Block
Diagram.

3、 AUDIO IC MAX9820
The MAX9820 Windows Vista®-compliant stereo headphone amplifier is
designed for portable
Equipment where board space is at a premium. It features Maxim’s
DirectDrive® architecture to produce a ground-referenced output from a single
supply, eliminating the large output-coupling capacitors required by
conventional single-supply headphone amplifiers.
The MAX9820 features an undervoltage lockout that prevents over
discharging of the battery
During brownout conditions, click-and-pop suppression that eliminates audible
transients on startup, a low-power shutdown mode, and thermal-overload and
short-circuit protection. Additionally, the MAX9820 suppresses RF radiation
received by input and supply traces acting as
antennas and prevents the amplifier from demodulating the coupled noise.
