   Common Problems  
   Product Specific Problems  
   
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 a proper Self - Test operation, remove the Analog (blue connector) cable from the back 
of computer.   
3. Turn on the monitor. 
   
4. This box also appears during normal system operation, if the video cable becomes disconnected or damaged.   
5. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.   
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer, because your monitor is functioning 
properly.  
Built - in Diagnostics  
Your monitor has a built - in diagnostic tool that helps you determine if the screen abnormality you are experiencing is an inherent problem with your monitor, or 
with your computer and video card.  
 CAUTION:  Before you begin any of the procedures in this section, follow the  Safety Instructions .  
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, the dialog shown below will continuously scroll 
through the screen. 
NOTE:  Self - test feature check is not available for S - Video, Composite, and Component video modes .  
NOTE:  You can run the built - in diagnostics only when the video cable is unplugged and the monitor is in  self - test mode .  
						

							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 from the back of the computer or monitor. The monitor then goes into the self - test mode.   
3. Press and hold the 1st and 4th buttons on the front panel, simultaneously for 2 seconds. A gray screen appears.   
4. Carefully inspect the screen for abnormalities.   
5. Press the 4th button 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 colored screens.   
The test is complete when the white screen appears. To exit, press the 4th button 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.
