Is there a blonde doing WP on the machine? If so I'd suspect white-out.

The white marks are caused by a large amount of pressure having been
applied to the lcd in the affected area. I'm not sure what exactly it does,
but it will leave a mark on the screen itself. Has anything been put on top
of the lcd while it was closed? I really don't know of any way to fix the
damage.

The laptop was used so I was not the original owner so I have no idea
how they originally appeared(addressing the extreme temperatures
question). My best guess would have been that some IDIOT closed the
cover while an item or items was/were between the keyboard & LCD (you
know, like used it as a "folder" ). I know it's not all that bad, but I
do a lot of graphic design work so I'm already predisposed to being
anal about these sorts of things. And doing graphic design on a flawed
screen makes it seem worse -as opposed to say just browsing the web or
word processing/whatever. It's just a shame that replacement LCDs are
so EXPENSIVE
