Dell E6400 Screen Flicker – Caused by display cable?

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:

Sometimes, the screen would turn off, flash black, and then display “Display driver stopped responding and has recovered” – see image below:

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.

Removing the base cover, I traced the problem to be with or around the LED cable (highlighted red in the image to the left)

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:
