K, I recently upgraded from my Rev A 500Ti to a new AlBook. However, I am loath to part with my Ti! I just purchased a new top case (b/c of the infamous cracks around the audio out port). However, before I completely take it apart, I have a very serious problem with the screen that I need to fix. It's not the typical horizontal lines all over the scrfeen that I've seen reported extensively. Instead, the problem I am having is limited to about the bottom 1/5 to 1/3 of the screen ONLY. It starts out as if the bottom section just kinda freezes like a jpeg. In other words, it will appear normal at first (my dock is fine, etc.) but if I move the cursor below the 1/3 point, it disappears completely. If I readjust the tilt of the screen, it sometimes refreshes it and I can then operated the cursor momentarily. Very shortly after this starts to happen (depending on the day) it starts to form a milky grey band in that area, until it gets progressively worse. At it's worst, I get a completely solid grey band across the bottom of my screen. The rest of the screen is perfect. Can someone PLEASE help me isolate what Part is causing this problem. Thank you! T.

I thought about that, but on opening it up no amount of messing with the cables could get the greyness to change. I guess that would have been too easy. Is it conceivable that b/c of the crack (which was there a long time) and the way it caused my case to distort, that I somehow fractured the video card? It's strange that bending the case will make the screen change, but messing with the cables has no effect. However, once it goes completely grey along the bottom, nothing fixes it besides rest.

Has anyone else run into this problem and figured out a fix? I have the exact same issue. I am out of warranty so sending it to apple is not an option.

I had the same problem and the only thing that fixed it for me was to replace the screen. Luckily I got a good second hand one cheap.

That is a normal problem for the TiBook screens. The hinges pinch a cable which creates the lines. I believe that you can fix this by replacing the cable which is extremely hard and then not closing the hatch.
