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 to 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 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 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 static. 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

3 Unit adjustments
Connect all the boards according to wiring diagram, connect with power and observe the display.
3.1 Method for using factory menu:
a) Press “INPUT”, “2”, “5”, ”8” and “0” in turn to enter level-one factory menu;
b) Press “CH+” and “CH-” to move the cursor to the adjustment page of the level-one factory menu
then press “OK” to enter;
c) Press “CH+” and “CH-” to move the cursor up and down;
d) When the cursor move to a certain adjust item, press “ VOL+” and “VOL –“ to adjust value;
e) Press “MENU” to exit to the level-one factory menu;
f) Press “EXIT” to exit the factory menu.
g) After exit the factory menu, press “SLEEP” to enter the factory menu again as long as power on.
h) “Power on mode” item of “Otherseting” menu: on= turn on; off =standby; memory=memory
function of turn on
3.2 White balance adjustment
3.2.1 Before adjustment
Before adjustment, the unit should keep working for over 30 minutes to be in a stable status.
a) In VGA channel, input VESA800*600/60HZ chessboard signal(VG848 Timing 854, pat 914),
enter user menu ADVANCE and perform AUTO to let picture display integrity, enter the factory
menu ADC Setting and perform ADC AUTO to do ADC correction.
b) In YPbPr channel, input 480i/60HZ 75%color bar and gray scale signal (VG848 Timing 968, PAT
918), enter the factory menu ADC Setting and perform ADC AUTO.
3.2.2 Four groups white balance adjustments (HDMI and VGA)
Allowable error range is below:
a) 12000K:
The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50)
The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,
+20)
The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15)
b) 9300K:
The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50)
The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,
+20)
The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15)
c) 6500K:
The white balance error range of the gray scale lower than 10IRE: X=(-15, +15) Y=(-50, +50)
The white balance error range of the gray scale between 10IRE and 30IRE: X=(-10, +10) Y=(-20,
+20)
The white balance error range of the gray scale higher than 30IRE: X=(-5, +5) Y=(-15, +15)
For BESTBUY, it needs to check if the white balance of 50IRE gray scale is up to the mustard at
9300K and 6500K (BBY channel of CA210).
3.2.2.1 ATV channel adjustment (same for AV, S-VIDEO)
Input 21-channel signal to the TV AIR, enter the factory menu “Color Temp”, set “Color Mode” to
COOL, 11-gray scale will display, fixed G GAIN, adjust R GAIN, B GAIN to let the color coordinate of
the ninth level be (272, 278); fixed G OFF, adjust R OFF, B OFF to let the color coordinate of the
