Ok, so this is a weird one. I recently replaced the screen with a new one off the bay, after I decided couldn't bear the dark marks that I'd noticed any more. I wasn't sure what they were caused by but presumed that the display itself was just knackered.

Thinking I'd solved the problem by installing a new LCD panel, I've continued using the machine as normal. However today I noticed that the same problem is back. I've been hammering my machine today with a lot of 3D work, and it's been hot all day (currently showing CPU at 80C!) Whilst this isn't abnormal for a Mac, I've come to the conclusion that the machine is getting so hot that it's destroying the LCD panels!

I guess I'd better go to an Apple store... it's out of warranty but this should not be happening, and must be a problem with the machine that has been present before. Thoughts?
 
They're pressure marks IMHO.
I'd guess you've got a slight bend in your lid, which means the screen is pushing slightly on the keyboard when it's closed.

I *don't* think they're anything to do with the heat :)

My laptop has always had a hard clamshell case on it, to the eye, the lid is as straight as it can be. Also if it was pressure the LCD would strobe/warp rather than just dim wouldn't it? I've seen iMacs where the heat has ruined the screen so wouldn't put it past the same happening to a laptop.

It depends on the exact pressure pattern.
If you take something with a unprotected screen and push lightly on it, you'll see an effect. Do this enough times and it becomes permanent.

These are a couple of examples from HP:

Still looks to me like you've got a pressure point or a slight kink in the lid and the screen is impacting the keyboard.

Heat is unlikely here- The difference between an Imac and a Macbook is that all the heat producing bits of the Imac (Processor, graphics card etc.) are behind the screen, whilst with a Macbook they're all in the bottom under the keyboard.

Pressure points are lighter than the surrounding areas, whereas the OP's issues are presenting themselves as dark splodges.

And seem to appear in relation to the hottest areas on the laptop body , ie closest to the body and below the keyboard (when I've shut the lid when the machine has been hot).

Do you run it with the clamshell shut?

If not then I doubt that would cause issues as the heat dissipates very quickly when it's not under load.

Nope, I never run it closed.

I'll often leave the machine rendering overnight, 12 hours at a time sometimes, flat out... that's why I think it's the heat that has caused the problems.
 
i agree with the op here and think it could be heat, i tai sit you operate it with the lid closed /external monitor when doing your 3d work? take it to apple and say what they say, be prepared for a hefty bill though. personally i'd change the thermal paste and get a better fan profile going if you are doing intense work quite often.
 
Since he's replaced the screen himself I don't think Apple will touch it, being modified and that..

I also think it is down to pressure on the lid, those 'hard cases' don't really do anything other than scratch the edges of the Mac when you take them off.
 
It could be pressure, but I'd be surprised, as I take really good care of my stuff and never rest anything on top. The case will spread the load a bit too, more reasons why I can't see it really being pressure.

I've just taken off the case and it looks perfect. Putting a metal ruler against it, the middle of the lid is slightly raised which I can only assume is normal.
