So, the machine still freezes, but the display doesn't corrupt (externally). It appears to only happen once the machine has fully warmed up and in normal use. A reboot will cure it sometimes, but many times it needs to be left off for awhile.

All of this points to an overheating problem (at least in my mind). If it were the processor overheating, it would turn off. If it were fan related (or one of the two fans not working), AHT would have detected it. The graphic anomalies and complete freeze seem to be related to the graphics subsystems (maybe not necessarily the video card, but the inverter, flex cable or components near or around the GPU). Either way, it's soldered to the system board, so a repair would include replacing it.

Before you write it off though, I would try doing a full backup to an external (with SuperDuper or CarbonCopyCloner) and then reinstall OS X clean. That would eliminate the possibility of a software issue (not that I can imagine this to be one, by any stretch of the imagination).

OK, I totally misunderstood that piece. I was thinking the machine was non-operable during this problem. It's just that the picture on the attached display doesn't work.

That's totally bizarre - I've been repairing PCs and laptops for a very long time now. I do it for a living. This makes absolutely no sense to me.

I'm leaning toward the flex cable. Perhaps as it heats up, the swelling of the plastics somehow causes a short or aggravates some existing wear on the cable.

How comfortable are you with disassembling it? (I assume it's not under warranty, right?)

I don't think that I want to disassemble it. Would it be good to take it and get it looked at? Also, if I were to disassemble it, what would I look for to see if it was a problem with the flex cable?

I would say that if you've never disassembled a laptop before, an Apple laptop is not a good one to learn on (they tend to be very tedious to get apart and put back together properly).

Another member sent his machine off to MacService.com (they are actually a member here) and was very happy with the service. I would PM member MacService and run it by them and see if you can get a ballpark quote.

You can have a look here.
Just select your model and look at replacing the display. It should show the cable.

When all else fails, try everything!

Sorry I couldn't give you some better news. It still might not be a bad idea to do a clean install of Mac OS - just in case. Or, by chance, do you happen to have Windows installed via Boot Camp? I'd be curious to see if it occurs while running Windows.

I found the problem! It was the flex cable, as was said before. I was talking to one of my friends, and the mentioned that their MacBook had a similar problem a while ago. He said that the problem turned out to be that the flex cable was loose, and he was able to fix it by shaking the screen when the screen messed up. I tried that today, and it worked. Thank you all for helping me narrow down what the problem was.

Sweet. Glad I was able to help.

Now that you know what it is for sure, I'd take a look at the disassembly instructions on ifixit.com and see if you can seat that cable better and/or use some electrical tape to better secure it.

Hi, i read all the thread and my problem is very very similar

the screen starts to "bump" and starts acting rare... after some times with the same problem, it seems to be solved in the same way here described, "shaking" the macbook...

I relaxed my self until saturday when i turn it on, i hear the start sounds and when i came back the screen was black, i supposed i tookseveral minutes then the display was maybe slept, but no, just 2 min passed..
i know its on, cause i can listen the start sound, inserted a dvd and i can listen to it... the screen is black

logic card problem? display?

I do think it's something "behind" the screen, because i have the same problem, but mine gets "solved" if i put my fingers and press at the left side of the screen. Once i stop pushing at that particular place it freezes again :s

So my guess is that its something that isnt "connected" anymore.

Hey guys I've been reading up on these issue people are having with their mac pro. I m having a screen problem where it started this week when the screen turn yellow with stip patterns, it only last a second, then it occurred randomly once a day and recently it last a minute of so. I closed my monitor to put it in sleep mode and then it was fine but then it happen right after again but his time didn t do anything and see what would happen, after awhile the screen turn back to normal but then the stripy lines stay for couple seconds.

I scanned my mac hardware and it seems fine but then i looked at my battery and it read poor so i thinking i need to replace it asap when I get back to the states.

Hopefully someone can tell me what's going on. Thank u
