Chosen Solution
Hi, I have a 5/6 year old MacBook. I’ve had the problems below for about 1 year, but they’ve steadily been getting worse to the point where I really need to do something about it! Here’s the problem: The bottom half of the screen appears to be inverted (as if someone has applied reverse video!) and there is a small (1/2 an inch) horizontal line half way in the reverse video zone with multiple multicolored vertical lines inside it. Inside the small horizontal line, it’s a dead zone as the display is shunted down by that amount. If I move the screen around, or apply pressure in random places on my MacBook, sometimes I can get the reverse video to fix itself (so I’m just left with the horizontal line). I’m certain it’s not my graphics chip as when I connect an external screen, everything looks fine Any ideas? Does anyone think it’s a cable issue or my screen itself? Is it worth just taking a look inside to see if anything is loose? Any help would be much appreciated! Nick.
I have seen this same issue a few times, sadly they have always been resolved by replacing the LCD Panel. Below is a link to the guide for replacing this panel.

The lines, however, certainly steer towards a faulty LCD Panel. Hope this helps, Wes
