WARNING FOR THE SAFETY-RELATED COMPONENT.

•There are some special components used in LCD

monitor that are important for safety. These parts are

marked on the schematic diagram and the

replacement parts list. It is essential that these critical

parts should be replaced with the manufacturer's

specified parts to prevent electric shock, fire or other

hazard.

•Do not modify original design without obtaining written

permission from LG or you will void the original parts

and labor guarantee.

TAKE CARE DURING HANDLING THE LCD MODULE

WITH BACKLIGHT UNIT.

•Must mount the module using mounting holes arranged

in four corners.

•Do not press on the panel, edge of the frame strongly

or electric shock as this will result in damage to the

screen.

•Do not scratch or press on the panel with any sharp

objects, such as pencil or pen as this may result in

damage to the panel.

•Protect the module from the ESD as it may damage the

electronic circuit (C-MOS).

•Make certain that treatment person's body are

grounded through wrist band.

•Do not leave the module in high temperature and in

areas of high humidity for a long time.

•The module not be exposed to the direct sunlight.

•Avoid contact with water as it may a short circuit within

the module.

•If the surface of panel become dirty, please wipe it off

with a softmaterial. (Cleaning with a dirty or rough cloth

may damage the panel.)

WARNING

BE CAREFUL ELECTRIC SHOCK !

•If you want to replace with the new backlight (CCFL) or

inverter circuit, must disconnect the AC adapter

because high voltage appears at inverter circuit about

650Vrms.

•Handle with care wires or connectors of the inverter

circuit. If the wires are pressed cause short and may

burn or take fire.

PRECAUTION

CAUTION

Please use only a plastic screwdriver to protect yourself

from shock hazard during service operation.

CAUTION

•There is two backlight, must distinguish between

the top (upper) and the bottom (lower), and be

careful of treatment it.

•MTBF (Mean Time Between Failure) of a backlight

is about 25,000 hours.

Top (Upper) Backlight Ass'y

(P/N: 6912E00001A)

Bottom (Lower) Backlight Ass'y

(P/N: 6912E00001B)

IF BRIGHTNESS OF THE LCD MODULE DARKEN,

REPLACE THE BACKLIGHT ONE OR ALL.

1. Application Object

This instruction is for the application to the LCD TV.

2. Notes

(1) This set uses an adapter, so connect the adapter and the

set correctly before adjustment.

(2) The adjustment must be performed under the correct

sequence.

(3) The adjustment must be performed in the circumstance of

25±5ºC of temperature and 65±10% of relative humidity if

there is no specific designation.

(4) The input voltage of the receiver must keep 100~220V,

50/60Hz in adjusting.

(5) The set must be operated for 30 minutes preliminarily

before adjustment if there is no specific designation.

✱"Heat Run" must be performed with the full white signal or TV

noise signal in the internal part of the set.

✱The time for "Heat Run" can be changed owing to production

plan.

3. PC Input Mode Adjustment

3-1. Required Test Equipment

(1) A pattern generator being in proportion to VG819 ; Pattern

of 64 tones

(2) A remote control

3-2. Preparation for Adjustment

(1) Perform "Heat Run" for more than 30 minutes in white

pattern.

(2) Connect the signal of pattern generator with LCD TV.

(3) Lean the set 45ºbackward. (Adjustment is easy.)

(4) Set the PC mode menu as below.

3-3. White Adjustment

(1) Approve the signal of 64 tones of XGA(1024 * 768).

(2) Select all the gain of R, B and G with using ADJ of remote

control.

(3) After making 62 tones, 63 tones and 64 tones not

distinguished with using each signal of R, G and B, finish

adjusting at the moment when the signal 62, 63 and 64 is

distinguished.
