Troubleshooting
If there is something wrong with the input signal, a message appears on the screen or the screen
goes blank although the power indicator LED is still on. The message may indicate that the
monitor is out of scan range or that you need to check the signal cable.
The location and the position of the monitor may influence the quality and other features of the
monitor.
1. If there are any woofer speakers near the monitor, unplug and relocate the woofer to another
room.
2. Remove all electronic devices such as radios, fans, clocks and telephones that are within 3 feet
(one meter) of the monitor.
3. Degauss the monitor if any devices were removed from the area.
.
A monitor recreates visual signals received from the PC. Therefore, if there is trouble with the PC
or the video card, this can cause the monitor to become blank, have poor coloring, noise, Sync. Out
of Range, etc. In this case, first check the source of the problem, and then contact a service center
or your dealer.
.
Judging the monitor's working condition
If there is no image on the screen or an "Sync. Out of Range" message comes up, disconnect the
cable from the computer while the monitor is still powered on.
.
If there is a message coming up on the screen or if the screen goes white, this means the
monitor is in working condition.
.
In this case, check the computer for trouble.
