Re: Blank Screen Now.

Backlight is torched, it happens without warning. These can be repaired, but finding the appropriate backlights, and trying to get this thing apart is a royal pain in the you know what! But your backlight has burned out! Sorry!

My samsung syncmaster 920nw picuture goes blank after a period of a couple of minutes. If I turn the power off and then back on the picture re-appears but goes off again. It is not he pc since it works...

If you get a flashing screen which show your screen for few minutes and then goes blank it may be an issue with the Monitor.

Try to restart the computer and go to BIOS setup screen. If you experience the same issue in BIOS then the monitor needs a repair or replacement for sure.

Westinghouse LCM-22W2 has "ghosting"

Usually, LCD monitor ghosting appears when the cable isn't tight, the cable is faulty, or low quality. The cable should be less than 8-10 feet long. Try using a different monitor cable (they're mostly interchangable) and see if the problem goes away. I'd put my money on the cable or a loose cable connection.

This issue could be either the Monitor inverter failing or it could be your Video card. If you have another computer available, plug the monitor into a different computer and see if you get the same behavior, if you do, then the monitor is failing and needs to be replaced. If on a different computer it works fine, then you may have a video card failing. Does it seem to happen the longer the monitor is on? Could be as it heats up, it starts to fail.

Blank screen

This looks like a problem with the video card or the power supply to the monitor. Try connecting a different monitor and if you still face the same problem then probably you may need to have a look at your video card or its connection in motherboard

My HP monitor (f50) has malfunctioned

Try these 2 steps if they don't work get back to me :)

Step 1. Connect the video cable and turn on the computer. What happens?
  • If the monitor screen remains blank (no startup screens or onscreen display messages), the monitor must be connected to another computer using a different cable to determine if the monitor is bad. Skip to the Step to connect the monitor to another computer.
  • If the monitor is capable of displaying boot screens but is unable to display Windows, use the following steps to set the computer to a compatible resolution:
    NOTE: Find the native display resolution for your monitor in the User Manual or in the product specifications for the monitor model. If you are unable to find the native display resolution for your monitor model, temporarily use 1024x768 for troubleshooting purposes.
    1. Turn on the computer and press the F8 key repeatedly when the first startup screen appears.
    2. If you are using Windows Vista, select Enable low resolution video (640 x 480) , press Enter , and wait until Windows opens. To set display settings that match the monitor, use the steps in the HP support document, Changing Display Settings, Background Image, and Screen Saver in Windows Vista . If you are using Windows XP, select Enable VGA Mode , press Enter , and wait until Windows opens. Continue using these steps to set display resolution. If you are using Windows 98 or ME, select Safe Mode and perform the following steps to enter into a standard VGA mode:
      1. Once Windows opens to the desktop in Safe Mode, click Start , and Run .
      2. In the Open field type msconfig and press Enter . The MS Configuration Utility window appears.
      3. Click the Advanced button, and select VGA 640 x 480 x 16 if it is available.
      4. Click OK and restart the computer.
      5. After Windows opens, click Start , and then click Run .
      6. In the Open field type msconfig and press Enter .
      7. Click the Advanced button, and remove the checkmark next to VGA 640 x 480 x 16 .
      8. Click OK . Do NOT restart the computer.
    3. After Windows opens, right-click on an open area of the desktop and select Properties (Windows XP, 98/Me) or Personalize (Windows Vista).
    4. In Windows Vista, Scroll down and click Display Properties . In Windows XP, 98, or Me, click the Settings tab.
    5. In Windows Vista, select the native display resolution size using the Resolution slider. Set Colors to Highest (32 bit) . In Windows XP, select the native display resolution size using the Screen resolution slider. Set Color Quality to Highest (32 bit) . In Windows 98 or Me, select the native display resolution size using the Screen Area slider. Set Colors to True Color .
    6. Click Apply after you have made your adjustment. The screen should blank out temporarily and come back.
    7. If you are satisfied with the new display settings, click Yes on the Monitor Settings windows. If you are not satisfied or if the screen just goes black, wait: Windows sets the screen back to the way it was before. Try another setting until you find a display configuration that is compatible with the monitor and meets your needs.
      NOTE: If the native resolution is not available, download and install updated video driver software for your computer. Updating the video driver software can add more resolutions (graphics modes).
    8. Restart the computer. The monitor should now display a full screen image in high quality. You are done.
Step 2: Connect to another monitor
Using a different cable, connect the monitor to another computer that has video. Turn on the monitor and the newly connected computer. What happens?
  • If the monitor works, the video hardware on the original computer is likely to be the source of the problems. You can try connecting the original computer to another monitor that works to update its video drivers.
  • If the monitor remains blank, repair or replace the monitor.

Nec monitor LCD1560V

Try changing the resolution of the screen. Right click on an empty area of the desktop and select properties. Now choose the Settings tab and try adjusting the slider for resolution and click on APPLY. The screen will go blank for a few seconds and will show up in the new resolution. If you find it satisfactory, click OK to keep it, or click NO to go back and try a different resolution.

You can also go into Control Panel and check the monitor properties from there.

Hope that helps!
