Attention: This service manual is only for service personnel to take reference with. Before servicing please read the following points carefully.

Safety instructions

1 Instructions

1.1 Be sure to switch off the power supply before replacing or welding any components or

inserting/plugging in connection wire

1.2 Anti static measures to be taken (throughout the entire production process!):

1.2.1 Do not touch here and there by hand at will;

1.2.2 Be sure to use anti static electric iron;

1.2.3 It’s a must for the welder to wear anti static gloves.

1.3 Please refer to the detailed list before replacing components that have special safety requirements.

Do not change the specs and type at will.

2 Points for attention in servicing of LCD

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.

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 Scope for operation

Scope for storage

humidity Scope for operation

Scope for storage

2.13 Display of a fixed picture for a long time may result in appearance of picture residue on the screen,

as commmonly called “ghost shadow”. The extent of the residual picture varies with the maker of

LCD screen. This phenonmenon 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.

0—+50 C

-20—+60 C

20%—85%

10%—90%

3. Points for attention during installation

3.1 The front panel of LCD screen is of glass. Wheng installing it please make sure to put it in place.

3.2 For service or instatallation 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.

software can download and write again automatic. if download and write repeated many times, please

turn off the TV and enter into IAP again, upgrade again.

Basic Working Principle

1. Analog signal flow process:

The signal received by antenna is fed into an integrated tuner (including high frequency and

medium amplification circuit). The tuner is controlled by the instructions (SDA, SCL) of MCU

N501(SDA5550), selects proper channels and conducts the right switching over of modes and outputs

video signal 2Vpp and audio signal 1Vpp after high and medium amplification and decoding.

Audio signal including SCART1,2 sound, AV sound as well as the YPbPr,DVI,D-SUB sound

signal switched over through N704 HEF4052BT (sound change-over switch), and Scart audio input

signal] is fed into N201 (MPS3410 sound processing and volume control)for the switch-over of audio

signal. The selected audio signal is fed, separately from left and right sound channels, into SRS

IC(M62494 virtual surrounding sound processing) N203, where it is subject to virtual surrounding sound

processing. The processed audio signal is fed, separately from left and right sound channels, into the

digital sound power amplifier N213/N214(MPS7720) for amplification and then further fed into

loudspeaker (in the future it may be changed into sound box for the improvement of sound quality) for

sound reproduction. M62494 is a virtual surrounding sound processing IC, which is subject to the control

of I/O port (77/78Pin) of N201 MPS3410.

The video signal output from the tuner, AV signal and Svideo signal, after matching with resistor,

directly enter, respectively from its own channel, into the main decoder IC N101(PanelTv-Svp), where

they are subject to video switch-over, A/D conversion, digital decoding, image zooming and OSD

superposition. Then they are output in electric level TTL to N601 DS90C383 (LVDS transmitting IC) for

driving the crystal display screen.

The Scart1 video signal and RGB signal, after matching with resistor, enter into the decoder IC

N401 (VPC3230 digital decoder), where they are subject to A/D conversion, and digital decoding. Then

they are fed in digital format into PanelTv-Svp for image zooming and OSD superimposition. Afterwards

they are further fed, in electric level TTL, into N601 DS90C383(LVDS IC) for driving the liquid crystal

display screen.

The Scart2 video signal and Y/C signal, after matching with resistor, enter into the decoder IC N401

(VPC3230 digital decoder), where they are subject to A/D conversion, and digital decoding. Then they

are fed in digital format (IUT656) into PanelTv-Svp for image zooming and OSD superimposition.

Afterwards they are further fed, in electric level TTL, into N601 DS90C383 (LVDS IC) for driving the

liquid crystal display screen.

For the specific circuit type and internal block diagram, please see the attached Fig.

2. Digital signal fl ow process:

(For the time being we call D-SUB, YpbPr signal also as digital signal. But in fact the two signals are

analog ones in terms of transmission and are only in digital format after conversion in ADC ) D-Sub

signal and YpbPr signal are, after matching with resister, fed into N703 video switch

(SN74CBT3257CDR). After switching over, the selected signal is fed into ADC N201 MST9883 for A/D

conversion. Then it is output in digital format of (24 digits RGB signal) to PanelTv-Svp PIP channel.

Through image zooming and OSD superimposition, it is then output, in electric level TTL for driving

LVDS liquid crystal display screen.

DVI signal is received through DVI receiving CMOS chip N761(TFP501DVI receiving chip

Has HDCP function). Then the received signal is output through DVI chip in digital format into

PanelTv-Svp PIP channel. After image zooming and OSD superimposition, it is output in electric level

TTL for driving LVDS liquid crystal display screen.

3. Realization of TELETEXT functi on

To realize the TELETEXT function of the main channel, this TV set adopts MCU

N501(SDA5550),SDA5550 of MICRONAS, which is both MCU and TELETEXT decoder. This set can

realize this function by two ways. One is that the radio frequency, after being decoded in SDA5550,

through parallel interfaced bus line, realizes the TELETEXT function in the form of OSD. The advantage

in this way is the result is relatively good and the characters/symbols are stable; the disadvantage is that

it is relatively slow for the TELETEXT function to appear through OSD. The other way is that the radio

frequency is decoded in SDA5550 into RGB signal, which is subject to A/D conversion in IC

N401(VPC3230 digital decoder) and then it is fed in digital format into PanelTv-Svp for the realization

of TELETEXT function. The advantage in this way is the speed the teletext comes out is faster and the

disadvantage is due to the fact that it is fed, in analog RGB form, into VPC3230 and goes through it, the

analog signal is easily subject to outside interference and thus the stability of characters/symbols is not

so good as the previous way (through OSD). We have chosen the first way. which in turn it is relatively

slow for the TELETEXT function to appear through OSD.
