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

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% ~ 80%

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.

Working Principle of the Unit

1、 ATV PAL signal flow

Receive RF PAL analog signal and sent it to XC5200C (D/A silicon Tuner controlled by main chip

2

MSD309PX through I
MSD309PX analog demodulation to be demodulated to get analog CVBS video signal and SIF sound

signal.

CVBS video signal is processed by back-end video decoder, anti-interlacing part, video processor

and zoom controller, then LVDS signal is outputted to drive display panel.

SIF sound signal is processed by back-end demodulator to get analog sound signal, then processed
by pre-amplifier, acoustic effect processor and volume controller to get two parts of signals: the analog
part of signal is sent to earphone amplifier MAX9820 to be amplified and then outputted to earphone jack;
the digital part of signal I2S is sent to digital audio power amplifier APA3160 to be processed by D/A
converter and power amplifier, then outputted to drive speakers.

2、 DVB-T signal flow

Receive RF DVB-T digital signal and sent it to XC5200C (D/A silicon Tuner controlled by main chip
MSD309PX through I
send out to main chip MSD309PX digital demodulation to be demodulated, then standard parallel
transmission flow is outputted to back-end demultiplexer and decoder to be processed.

Video channel: demultiplexing digital video signal is processed by MSD309PX decoder and video
processor, then LVDS signal is outputted to drive display panel;

Audio channel: demultiplexing digital audio signal is processed by MSD309PX decoder and audio
processor, then double-sound-track analog audio signal (stereo) is outputted to MSD309PX to be

IC Block Diagram

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.

2、 AMP IC APA3160

The APA3160 is a digital input, stereo, high efficiency, Class-D audio

amplifier available in a TQFP7x7-48P package.
The APA3160 accepts the digital serial audio data and using the digital

audio processor to convert the audio data becomes the stereo Class-D

output speaker amplifier. This provides the seamless integration between

the codec and the speaker amplifier.
The APA3160 is a slave device receiving clocks from external source, and

the Class-D’s PWM switching frequency is 352.8kHz for the sampling rate

44.1kHz or 384kHz for sampling 48kHz, depend on the input signal’s

sampling rate.

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.

Appendix: Installing the Stand

If the stand is provided, please read these instructions thoroughly before attempting this installation.

You must install your TV into the stand in order for it to stand upright on a cabinet or other flat surface. If you intend
to mount your TV on a wall or other vertical surface, you must remove the stand column.

Cautions:

Make sure that you handle your TV very carefully when attempting assembly or removal of the stand. If you are not
sure of your ability to do this, or of your ability to use the tools necessary to complete this job, refer to a professional
installer or service personnel. The manufacturer is not responsible for any damages or injuries that occur due to
mishandling or improper assembly.

When using a table or bench as an aid to assembly, make sure that you put down a soft cushion or covering to prevent
accidental scratching or damage to your TV's finish.

The speaker is not intended to support the weight of your TV. Do not move or handle your TV by the speaker. This
can cause damage to your TV that is not covered by the manufacturer's warranty.

Before attempting assembly or removal of the stand, unplug the AC power cord.

Installing the stand

To install the stand:

Locators

Locating grooves

Screws

1. Remove the stand from the box and place it on a table or

bench.

You must pay attention to the direction of the stand. The

wide portion of the stand should go towards the front of
the TV.

2. Lay your TV flat (screen down) on the edge of a table or

bench. Make sure that you put down a soft cushion or
cloth so that your TV is not scratched.

3. Align the stand base with the TV, move the stand base

gently until the locators on the stand column align with
the locating grooves on the stand. And align the holes in
the stand with the holes in the stand column, then secure
the stand to the column with provided screws.

To remove the stand from the TV, just detach the
screws from the stand column.
