Display problem - bands across bottom 1/3 of screen

Hi,

I have just replaced the display cable on this MBP, it had a grey band across the bottom 1/3 of the screen with some vertical coloured lines in the center. You can see the ghost of a window through it as you move finder windows around. The band would flicker or occasionally disappear on hinge movement. So figuring it was the cable, I replaced it,(have done this before a couple of times) On this occasion the fault remains, unchanged. The only thing I noticed while in there was the left hand side of the inverter cable appears to have pinched at some point. Not sure of that could be related.

Any thoughts much appreciated,

Mike
