Dodgy screen on dell 8600 latop

[Chris Jones]

Hi,

This is probably OT for this list, but I have tried a few others and got 
nowhere, so I thought I would try my luck on this list.  Apologies in 
advance.

I have a dell 8600 (running FC5), which has developed a problem with the 
screen, in that from time to time the colours go odd (like its losing 
one of the red/green/blue signals). I've may have narrowed down the 
problem to hardware and not software, and a possible dodgy connection 
between the main unit and the lid, at the end inside the lid. However, I 
haven't gone any further since I don't want to take the lid apart 
without knowing what I am doing. Has anyone done anything similar ? I've 
googled around but not found any information on how to do this safely - 
Does anyone know of a resource I can look for this. Ideally a nice walk 
through with pictures :) ?

cheers Chris
