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 you see a
“CHECK SIGNAL” image on the screen,
(shown below) the monitor is function
properly, and the problem is at PC side, or
signal cable.
