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.

NOTE: This box also appears on the monitor screen, if the video cable is disconnected or damaged. 4. Turn Off your monitor and reconnect the video cable; then turn on your computer and the monitor. If your monitor remains dark after you reconnect the cables, check your video controller and computer. 26

Onboard diagnostics
Your monitor has a onboard 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 onboard diagnostics only when the video cable is unplugged and the monitor is in self-test mode.
To run the onboard diagnostics: 1. Ensure that the screen is clean (no dust particles on the surface of the screen). 2. Unplug the video cables from the back of the computer or monitor. The monitor then goes into the self-test mode. 3. Press and hold the Exit button (button 4) for four seconds to enter the OSD lock/unlock menu.
4. Select the icon to run the onboard diagnostics. 5. Carefully inspect the screen for abnormalities. 6. Press the Up button (button 1) on the back cover again. The color of the screen changes to gray. 7. Inspect the display for any abnormalities. 8. Repeat steps 6 and 7 to inspect the display in red, green, blue, black, white, and text pattern screens. The test is completed when the text pattern screen appears. To exit, press the Up button (button 1) again. If you do not detect any screen abnormalities upon using the onboard diagnostic tool, the monitor is functioning properly. Check the video card and computer.
