I think that my display has somehow broken, but before I sit on hold with customer service tomorrow, I figured I'd throw a post up here-

The display has developed two discolored lines slightly to the right of the center of the display. The lines run vertically from the top to the bottom of the display. They are one pixel wide and two pixels apart. They are not completely dead, just much darker than the rest of the display. I saw them a few days ago, but they disappeared after a few minutes. now they've come back and won't go away.

I can't imagine why this has happened. I treat this thing like it's made of glass. I guess I have some hope that this is a known issue, perhaps something that can be fixed with a jiggle of some internal component. Thanks in advance for any help.
