Troubleshooting

WARNING:  

Before you begin any of the procedures in this section, follow the 

Safety Instructions

.

Self-Test

Your monitor provides a self-test feature that allows you to check whether your monitor 
is functioning properly. If your monitor and computer are properly connected but the 
monitor screen remains dark, run the monitor self-test by performing the following 
steps:

1.

Turn off both your computer and the monitor.

2.

Unplug the video cable from the back of the computer. To ensure proper Self-Test 
operation, remove all Digital (white connector) and the Analog (blue connector) 
cables from the back of computer.

3.

Turn on the monitor.

The floating dialog box should appear on-screen (against a black background), if the 
monitor cannot sense a video signal and is working correctly. While in self-test mode, the 
power LED remains white. Also, depending upon the selected input, one of the dialogs 
shown below will continuously scroll through the screen.
