Is my kindle beyond repair?

When I turned my kindle on this morning it did this: http://i.imgur.com/V93JrOS.jpg?1

When I shut it down, the lower right part of the screen that has the text and gradient turn off, but the rest stays like it is in the image. I can still turn pages and stuff and see the text change in that itty bitty part that has text, but the rest is pretty much borked.

It’s been in my backpack for awhile but I don’t think it’s really suffered any major abuse in there. I’m perplexed why this happened.

Is there anything I can try? Ever had this problem before?

I guess I’ll call Amazon but it’s out of warranty and everything so I doubt there’s anything they’ll do for me.
