Last week, I started having trouble with my Dell E6400 Notebook.
There is an intermittent “flashing” on the screen – kind of a “solarising” of the colours, and flickering – it also displayed as “split screen” – split horizontally, displaying the same image top and bottom, but at very low resolution.
See flickering / solarising:
I can reproduce the problem by holding the laptop by the left hand side, towards the top of the base, and sort of pressing the base cover.
If i pressed the cable or where it was connecting to the main board, the flickering problem could be reproduced.
I removed the cable, cleaned it, removed all dust from around it and replaced.
This problem is not totally fixed – but it happens far less now than it did before.
I suspect very strongly, I will require a new cable.
I generally (through bad habit) tend to pick the laptop up on that side of the base – so I think the cable may of worn out.
Fingers crossed a new cable is all that is required, not a whole new motherboard!
For reference, the cable I have is pictured below:
