TROUBLESHOOTING
If your monitor fails to operate functionally, it may
be possible to correct the problem by making simple
checks as follows:
Problem
Blank screen
(*NOTE)
Display position
off-center
Display too small
or too large
Display too bright
or too dim
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 if 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
"NO SIGNAL" image on the screen, the
monitor is functioning properly, and the
problem is with the PC side or signal cable.
