Display Problem on MacBook Pro 13-In: red blotch when screen is dark/black

There's just the one, which doesn't move. I.e., as I move the (black) screen shot, the red blotch is stationary (appears on different parts of the screenshot as I move it. So, it's the screen, then?

Their latest guess is that this is pressure on the display (where the apple is, hence the unusual design). They replaced the display (again) -- and gave me a shell to keep it safe. So far, they've now replaced the display four times, and the computer itself twice. I don't know. I'm not too optimistic. What exactly is your discoloration. (Btw, not sure if I understood this when I wrote about this before, but the blotch/mark, whatever it is, does NOT move with the screenshot (i.e., it was on the display itselft).

Let me know what you find out. Right now, I have no blotch (new display). But, like I said, I'm not optimistic. I found a guy in another forum who had the same exact shape as mine (summer 2011); don't know what happened to his. Obviously, something is going on, but Apple doesn't seem to know what it is.

Wellllll, let's see. What they did in February seems to maybe have worked (for the moment?) -- i.e., the problem has not returned. Since then, I have seen others (like my son) who have the same problem (he just didn't know it because he wasn't watching videos on it). He believes it may be a design defect in the MacBook Pro (some kind of pressure on the screen when the lid closes). Which would explain why there are probably a lot of people (like you and I -- and my son) have experienced the same thing. (Is your blotch red and in a kind of "T" shape?) Again, my Head Genius at my local Apple Store believes that it was me putting pressure on the Apple from the outside, which, he said, explains to odd configuration. Maybe. All I can say is that since they gave the new screen AND a shell, it hasn't returned. Of course, I've gone this long (I think) without it reappearing, so I kind of live in fear every time I watch a video that it will be back!

Also, there is a posting somewhere (I have to go look for it -- on one of these forums) with a photo that replicated my problem precisely -- same spot, same shape, same size. His was posted in summer 2011, I believe (so, this kind of thing has been going on for a long time). I responded, but never heard from him.

So, that makes at least four of us -- different parts of the US (and the world?) -- all with the same problem, 2011-13, all with the same Mac. Interesting that my Apple people claimed to have no knowledge of the problem AT ALL. They were totally stumped.

That's interesting. If true, though, the real question is whether you and I (and my son, and that guy from 2011) are doing it by putting some kind of pressure on the outside of the machine at its center (i.e., the Apple) -- or is it, as my son suspects, some kind of design defect in the MacBook itself. Remember that, for you, me, for my son, it's not noticeable under "normal" circumstances. It's just with that black background.
