TROUBLESHOOTING

If your monitor fails to operate functionally, it might
be possible to correct the problem by making simple
checks as follows:

Refer to the operation instructions for your computer
or 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.

You must include the power cord if you return the
monitor for service.

* 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 you see a
“NO SIGNAL” image on the screen
(shown below), the monitor is function
properly, and the problem is at computer
side, or signal cable.
