5. Trouble Shooting Instructions
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 doesn’t
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 message appears. While in self-test mode, the power LED remains white.

NOTE: This box also appears during normal system operation, if the video cable
is disconnected or damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your
computer and the monitor.
If your monitor remains dark after you reconnect the cables, check your video
controller and computer.
Built-in diagnostics
Your monitor has a built-in diagnostic tool that helps you determine if any screen
abnormality you experience is an inherent problem with your monitor, or with your
computer and video card.
NOTE: You can run the built-in diagnostics only when the video cable is
unplugged and the monitor is in self-test mode.
152 34
To run the built-in diagnostics:
1. Ensure that the screen is clean (no dust particles on the surface of the screen).
2. Unplug the video cable(s) from the back of the computer or monitor. The
monitor then goes into the self-test mode.
3. Press and hold button 1 for 5 seconds. A gray screen appears.
4. Carefully inspect the screen for abnormalities.
5. Press button 1 on the front panel again. The color of the screen changes to red.
6. Inspect the display for any abnormalities.
7. Repeat steps 5 and 6 to inspect the display in green, blue, black, white and text
screens.
The test is complete when the text screen appears. To exit, press button 1 again.
If you do not detect any screen abnormalities upon using the built-in diagnostic tool,
the monitor is functioning properly. Check the video card and computer.
