Warning Messages

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.

Environment

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.

Userful Tip

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.
