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

Attention: This service manual is only for service personnel to take reference with. Before

servicing please read the following points carefully.

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 0 ~ +50

o

C

Storage range -20 ~ +60

o

C

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.

Working principle analysis of the unit

RF signal from antenna is sent into TUNER301 to be processed by HF-amplified and

frequency mixing, then IF signal is outputted to SWF Z301 to be IF filtered to get ideal IF

characteristics, then the signal is sent to main chip N101(RTD2674S)-27#,28# to be

amplified by inline IF amplifier and synchronous demodulated to get CVBS.

Video and audio signal from AV, SCART are sent to main chip N101 directly; video and

audio signal from VGA and HDMI1, HDMI2 are also sent to main chip N101 directly.

Main chip N101(RTD2674S) is a special large scale IC with full functions, such as HDMI

interface process, video decoding, video switch selection, A/D and D/A transformation,

interleaved/successive scans, mode transformation, OSD and low-voltage difference

output process, etc.; furthermore, it also has functions of audio selection and process,

MCU, etc.; external video signal is processed by main chip N101(RTD2674S), 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(RTD2674S) is sent to sound amplifier

N308(R2A15112FP) to be amplified and then to speakers.
