Hi, I have a dell x200 . The lcd has suddenly gone all white. So far I have done the following. Checked the conections. Changed the lcd. Removed the lcd. Put in a new (spare) lcd Now with an external monitor I get an all black screen that shuts off after about two seconds. In the time of those two seconds I can clearly see a flashing prompt ( - ). The screen seems to shut off as the laptop starts to read the cmos. I have disasembled the entire laptop and still no change. I have frozen the video chips with cool spray and still no change. It apears to me that I have a corrupt bios or cmos but I cannot try to correct it because I can't see the d*m screen. Oh , I almost forgot, I just finished re installing winxp when all this happened. The laptop apears to run normally exept no video. I would apresiate any constructive thoughts on this problem.
