TROUBLESHOOTING

If your monitor fails to operate functionally, it may

be possible to correct the problem by making simple

checks as follows:

Refer to the operation instructions for your computer/

video adapter to ensure that you have the correct signal

output source for the monitor. Ensure that the switches

on the video adapter are set correctly for operation

with this monitor.

If the above steps fail to correct the problem contact

your dealer for servicing by qualified service

personnel.

Please remember that the monitor should be returned

for servicing together with the power cord.

* Note: You can easily distinguish the problem is on

the monitor or on the computer by using the

monitor’s built-in selftest function.

With the monitor power ON, disconnect the

signal cable from monitor. If there is no image

on the monitor screen, disconnect the signal

cable. If a full-white image is diaplayed on

the screen, the monitor is function properly,

and the problem is at PC side, or signal cable.
