My screen has a big black mark in it, and black is showing up in spots along the edge now as well, which I guess means it is peeling apart. The easiest installation solution seems to be to replace the entire lid/screen assembly.
I have found one here. There's no part number, probably because it's a whole assembly of parts. Is there any possibility of incompatability, including everything fitting together good and locking closed? (I don't know what the *7 is after the title, I think it's just the seller's own classification.)
Also, 14.1" is the screen diag. size, not the lid size, right? :-)
