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 if 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.  Disconnect all video cables from the monitor. This way, the computer does not 

have to be involved.

3.  Turn on the monitor.

If the monitor is working correctly, it detects that there is no signal, and one of the 
following messages appears. While in self-test mode, the power LED remains white.
