PRECAUTION 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.

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.
