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 manufacturer 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.
