A couple of days ago I noticed a line like and L on my screen. It is a whitish color - sort of like when you gently press on a computer LCD. Well, I noticed it looks like a scorch mark of sorts on my screen in the shape of 4 or 5 keys. Googling this only found one thread saying if you close your MBP while it is still hot can create scorch marks of the keyboard on the screen. This is JUST what it looks like. I am a bit upset and angry because I take very good care of my MBP and this shouldn't happen to any computer. (On the day this happened I was doing video editing and playing video games - so it would of been hot). Has anyone else heard of this and what can I do about it?
