• There are some special components used in LCD

monitor that are important for safety. 

marked    on the schematic  diagram  and the
replacement parts list. It is essential that these critical
par ts 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.

• 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  cer tain 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.)

BE CAREFUL ELECTRIC SHOCK ! 

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

inver ter 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.

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