Hi.
I have a Toshiba Satellite L10 (or L20 - not sure).
Recently the laptop screen packed up. When i turn the laptop on, i get a few seconds of startup on screen, then screen goes white. Not bars or anything, just all white. I can connect an external monitor, but can only see something after windows startup if i start in Safe Mode.
Any ideas on what might be wrong, and how to fix it? It is only 16 months old, just out of warranty.
