Kindle 3 (keyboard) WiFi screen issues

[oligneisti]

I have searched for a topic about this problem and not found anything.

The screen on my Kindle 3 froze while I was flipping fast through the pages of the main menu. I tried replacing the screen but it didn't work (the new screen kind of "fogged over" and froze). I tried resetting it and using Kubrick but nothing happens. For some reason the edges of my screen, which is usually covered but the frame, seem to react and change color when restarting.

I can access the Kindle as a drive with my computer, it does boot up, I can log in and the WiFi is working since I can send books to the Kindle through Amazon.

Does anyone have a clue what could be wrong?
