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...

Hi, Sounds either a backlight problem (inverter or tube light) or the display interface. Since you have confirmed that it is your LCD monitor, your best bet perhaps is to seek the services of a qualified professional. Should you venture in doing it yourself (DIY), You need to open up the casing. A step by step procedure is better illustrated here . The working principles of notebook/laptop displays are nearly identical to your LCD. Hope this be of some help. Post back how things turned up or should you need further information. Good luck and kind regards.

I had the same problem, you must call Viewsonic to change your screen. The DVI input on the screen is dead.
