IML Tech September 19, 2009 | Caled, I think my webcam is defective. Jack August 16, 2009 | Dell Latitude C800 LCD problem intermittent, no 100% indicative of back light or inverter failure so I am wondering if the LCD screen could be faulty?

The only sign of back light failure (after educating myself via this site) is infrequent and very brief screen flickering from full illumination to black out…nothing in between.

Restoring your system won't have any effect on it since you've indicated an external monitor worked fine with it. 08-28-2008, 05:08 PM #4 para.lax Registered Member Join Date:

The laptop screen flickers and shows the image for a fraction of a second then continuously comes and goes. HP will not help unless I send in for $400. Actually, as a follow up to my previous post, my problem was not with my display switch. I spoke with a nice lady (details below) that said she would pursue my complaint with HP's legal department.
You should see the windows logo come up when it comes back on and you will be able to type in your password. Could be a problem with the motherboard. Report Dr. Dave August 26, 2009 | Toshiba Satellite M35X-S349 laptop has a pink line in LCD.
