Note
Before you call for assistance, run a self-test to see if the monitor is working correctly. Contact
a Service Center for problems that you cannot solve by yourself.
Running a Self-Test
1.
Turn off both your computer and the LCD Display.
2.
Unplug the video cable from the back of the computer.
3.
Turn on the LCD Display.
The figure shown below ("Check Signal Cable") appears on a black background when
the LCD Display is working normally even though no video signal is detected: While in
the Self-Test mode, the LED power indicator remains green and the figure moves around
on the screen.
4.
Turn off your LCD Display and reconnect the video cable; and then turn on both your
computer and the LCD Display
If your LCD Display screen remains blank after you've run a self-test, check your video con-
troller and computer system. Your LCD Display is functioning properly.
