Try a "Hard Reset" my screen was doing something similar. The backlight wasn't completely going out and I could see very faint lines on the screen. A soft reset fixed it temporarily. But a Hard Reset took it away. There is a program called pocket controller that may give you access to the units screen to at least back everything up before you hard reset and lose everything.

Also this post probably doesn't belong in this area. Could someone move it?
