MacBook Pro 17" banding. LCD or Cable?

[JuiceeciuJ]

My macbook pro has an issue with banding periodically across the bottom portion of the screen. Usually a little twist of the screen or tap on the back fixes the problem but lately it's being very stubborn. I'm wondering if this issue is an LCD issue or a cable issue. I'm hoping it's a cable issue as the problem has been very periodic. I've attached a couple pictures of the problem. So i guess the question is LCD or LCD cable?

This could be the cable, the display or the video card.

Try a different cable if you have one. If it's still there you've eliminated the cable.

I think I'm going to order a replacement cable and try and replace that first since it's probably the least expensive of the three. Any idea on how hard it would be to just replace the cable? Would I have to completely remove the lcd from the frame first?
