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.

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, Video
mode not supported, etc. In this case, first check the source of the problem, and then contact a
service center or your dealer.

If there is a message coming up on the screen or if the screen goes white, this means the
