Troubleshooting

Check the following before calling for service.

No image appears

Is the power cord of the

monitor connected?

Is the power indicator light

on?

Is the power on and the

power indicator green?

Is the power indicator

amber?

Do you see an "OUT OF

FREQUENCY" message

on the screen?

Do you see a

"NO SIGNAL" message

on the screen?

The screen is flickering.

Is the vertical frequency

less than 70Hz or is your

monitor set to the

interlaced mode?

Do you have any

magnetic material such

as adapter, or high-

voltage line near to your

monitor?

Do you hear a "~ding"

sound while the monitor

is flickering?

Check and see if the power cord is connected properly to

the power outlet.

Press the Power button.

Adjust the brightness and the contrast.

If the monitor is in power saving mode, try moving the

mouse or pressing any key on the keyboard to bring up

the screen.

Press the digital select button.

This message appears when the signal from the PC

(video card) is out of horizontal or vertical frequency

range of the monitor. See the ' S pecifications' section of

this manual and configure your monitor again.

This message appears when the signal cable between

your PC and your monitor is not connected. Check the

signal cable and try again.

Set the vertical frequency to 72Hz or higher, and

consult the video card user manual for instructions on

converting to a non-interlaced mode.

(You can set this option under the Display icon of the

Control Panel.)

Remove magnetic sources, such as power

adapters, speakers, or high-voltage lines, away from

the monitor.

Use the normal degaussing function. This function

clears the screen and reduces any screen blur that

may occur due to the surrounding magnetic field. The

screen may flicker for about 5 seconds, accompanied

by a "~ding" sound.
