If your computer screen is not responding, use the following troubleshooting techniques to help you determine the source of the problem and resolve it.
Troubleshooting Your Computer Screen
- Listen to the computer and look at its indicator lights.
- If the computer makes beeping sounds when it is turned on, a card, cable, memory module, or processor may have come loose.
- If you cannot hear the computer's fans spinning, it means the problem is related to the computer, not the monitor.
- If you can hear the computer's fan spin and see lights on the computer, the video cable connection or the monitor are likely the source of the problem.
- Check your computer's power indicator light to see if the monitor is being powered properly. If the power indicator light is not on, check the monitor's power cable connection.
- Connect the computer in question to a different monitor. This should help you determine which device – the monitor or the computer – is the problem.
- If the newly-attached monitor does not display anything, it means that the computer is the problem. Most likely, the video cable and/or video connector is damaged. If the new monitor works, the original monitor is the problem.
- If your video cable and/or video connector are damaged, inspect the video cable and video connectors. Check for broken cables and damaged connector pins. Turn both the monitor and computer off and try to straighten bent pins with a small metal tube.
If Your Original Monitor is the Source of the Problem
- Replace the monitor power cable and then turn on the monitor. If the monitor turns on, you are done. If the monitor does not work after replacing the monitor power cable, call technology support at (208) 496-1411.
- Replace the video cable and then turn on the monitor. If the monitor turns on, you are done. If the monitor does not work after replacing the video cable, call technology support at (208) 496-1411.
