PRECAUTION

WAR NI NG FOR THE SAFETY-RELATED COMPONENT.

• There are some special components used in LCD monitor that are important for safety.

marked on the schematic diagram and the replacement parts list.

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.

It is essential that these critical

These parts are

CAUTION

Please use only a plastic screwdriver to protect yourself from shock hazard during service operation.

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.

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.)

• Handle with care wires or connectors of the inverter circuit. If the wires are pressed cause short and may burn or take fire.
