Attention: This service manual is only for service per sonnel to take reference with. Before
servicing please read the following points carefully.
Safety precautions
1. Instructions
Be sure to switch of f the power supply bef ore replacin g or weldin g any component s or
inserting/plugging in co nnection wire Anti static measures to be take n (throughout the entir e
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 a must for the welder to wear anti static gloves.
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 op eration volt age of LCD screen is 700-825V . Be sure t o t ake prop er measure s in
protecting yourself and the machine when testin g the syste m in the course of nor mal operation or
right after the power is s witched off. Please do not touch the circuit or the met al part of the module
that is in o peration mode. Relevant operation is possible only one minute af ter 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 o perate the set or do any inst allation work in bad environme nt such as wet bathroom,
laundry, kitchen, or nearby fire source, heating e quipment and devices or exposure to sunlight etc.
Otherwise bad effect will result.
2.5 If any fo reign 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 scr een is not working af ter 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 p lug in the connection wire when the module is in operation o r just af ter the
power is o ff because in this case re latively high voltage still remains in t he 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 cir cuitry in LCD T V 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 lot s of connection wires between p arts behind the LCD screen. When servicing or
moving the set plea se take care not to tou ch or scratch them. Once they are damaged the screen

3. Flash writing programs
Flash write N5, N9, N13, N24
Flash write W24CXX.EXE to N13, N24 with self-made flash write tool on the line.
Note: software upgrade of N5 from socket X51
software upgrade of N9 from USB interface
software upgrade of N13, N24 from HDMI and VGA interface separately
Adjustment of main board and high frequency board
a) Connect the main board and high frequency board according the wiring diagram. Connect X402
(on main bo ard) with IR board and insert the plug of power supply a ssy into X 707, now the
indicator light of IR board is red.
b) Press POWER button on the remote control set, now the indicator light of IR board is blue.
c) Check if picture and sound are normal of all the channels, if STEREO/SAP can be identified
correctly. Check AV-OUT function: the picture and sound of AV-OUT should be the picture and
sound of the current channel at TV/AV1/S/AV2; the sound from AV-OUT should be the sound of
the current channel at the other signal source, while the picture don’t need to check.
4. Unit adjustment
4.1 Adjustment of unit connection
Turn on the TV and check if it is normal: display LOGO about 8 seconds later, display picture about
12 seconds later.
4.2 Aging
a) Turn on the TV, select TV channel without signal input.
b) Aging for an hour in the aging room.
4.3 ACD calibration and White balance adjustment (use CA210, VG849 generator)
Method of entering factory menu: enter “INPUT” menu, then press”2 5 8 0” one by one.
Note: Coordinate of cold color temperature 9300K is (X=283, Y=299), coordinate of warm color
temperature 6500K is (X=311, Y=329).
YPbPr channel (YPbPr1 or YPbPr2)
a) Input SMPTE COLOR BAR signal of 480P (TIMING:976, PATTERN:984)
b) Set brightness to 50; contrast to 50
c) Enter factory menu and perform “Calibration”
VGA channel
a) Input 16-level gray scale signal of the mode 800*600 @60 (TIMING:885, PATTERN:920)
b) Set brightness to 50; contrast to 50
c) Enter factory menu and perform “Calibration”
d) Select “color temperature” of “COOL”
e) Enter “color temperature setting” menu
f) Fix GREEN GAIN at 1 28, adjust RED GAIN, BLUE GAI N to set the color coord inates of
fourteenth level to (X=283, Y=299).
g) Set the color coordinates of warm color temperature (WARM) to (X =311, Y=329) using the
same method.
