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.

Adjustment Instructions

1 Safety Instructions

1.1 Power supply must be cut off when replacing or welding any component or inserting / pulling out connective lines;

1.2 Anti-electrostatic measures must be carried out during the whole producing processes!

a) Do not touch IC by hands at will; b) Use anti-electrostatic iron; c) Welder must wear anti-electrostatic glove;

1.3 Replacing any component with special safety requirement must refer to component list without changing its specification and model at will.

1.4 Power supply voltage must be ~(100-240) V±10% 50 Hz.

Note that U disk must not be pulled out or the unit must not be cut off during the upgrading process.

Working principle analysis of the unit

RF signal from antenna is sent into Tuner chip N401 to be processed by HF-amplifier and mixer to get digital IF signal DIF, then DIF signal is sent to main chip N101（MST6E182VGC）.

HDMI signal is sent to HDMI switch chip N201 to be switched by three-way-signal-selection switch and then sent to main chip N101 （MST6E182VGC）.

Video and audio signals from AV, YPbPr , VGA, USB are sent to main chip N101（MST6E182VGC）directly.

Main chip N101（MST6E182VGC）is a special large scale IC with full functions, such as HDMI interface processing, video decoding, video switch selection, A/D and D/A transformation, interleaved/successive scan processing, mode transformation, OSD and low-voltage difference output processing, etc.; furthermore, it also has functions of audio selection and audio processing, MCU, etc.; external video signal is processed by main chip N101 （MST6E182VGC）, then 4 pairs of difference signals and one pair of clock signals are outputted to LCD to display; external audio signal processed by main chip N101（MST6E182VGC） is sent to sound amplifier N402 to be amplified and then sent to speakers.
