Dell Inspiron 8600 lcd flashes colors
 |
My daughter's Dell Inspiron 8600 laptop screen went blank. The problem was not the backlight, so we installed a new screen. When turning the laptop on, the screen slowly flashes from red to green to blue etc. When using an external monitor, we can see that Windows always starts in the Safe mode. I would appreciate any ideas!

Sounds like a video diagnostic. Flashing from red,green,blue, etc, is an onboard video diag that runs on Dell systems. Is there any beeping? Will it boot past that, eventually?

Hi Alex,
Here is some more information on the Inspiron lcd problem. I checked under Manage, System, and found that the event log file is corrupt. The Device Manager does not show any Monitors, so it seems like the pc doesn't detect the new screen. I checked the flat connecting wire and it seems ok. The old lcd was UXGA 15.4" Oct.31, 2003, and the new one UXGA 15.4" May 14, 2004. We upgraded the Bios to the latest version, but it didn't help either. I would appreciate any additional troubleshooting ideas!
