Today, my monitor went to a multicolored candy-striped screen. I have to keep unplugging it (at the back of the monitor) until it works again. Every time I plug it back in, it's a different weird screen...

1) Replace the Monitor Cable, VGA is generally a Blue connection and DVI is a cream/white.

2) Make sure there aren't any bent pins in the end of the cables

3) Try the monitor on another working computer to verify it works or not

4) Replace the monitor.

If the monitor works on another computer then chances are that your computer has corrupted video drivers or a bad video card.

Sounds like your video settings are out of range. Start up your laptop in 'safe' mode, set the video to 1200x1024 and 60Hz then reboot normally.

Post back on the results.

Blank screen

probably failure in the LCD controller IC in the lcd controller board. that no signal was sent out to the lcd driver IC thus you could only see white display. A replacement of LCD panel is the best solution. I suggest to bring the unit to an authorized service center to properly diagnose & fix the problem. regards

LCD monitor goes blank

It appears that the display resolution set in your display properties is out of the range that the LCD can display.

Try this.

Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)

Check signal message when data cable unplugged. blank screen when data cable plugged

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...
