lcd only shows white

[chips2481]

I have a dell inspiron 8200. When you power it up to a external monitor it will work correctly and on the laptop it is only white of course. Does anyone have any ideas?

Is this the same laptop you were trying to fix before in another thread a few days ago? If so, why not go back to it?

oh I thought I posted that one on the dell forum, oops

Could be either a bad logic board or the cable that supplies the video signal to the LCD could be loose. In my experience it's almost ALWAYS a loose video cable.

Ok great. So you have seen a white display with a loose cable then?
