I bought one of these years ago when they first came out, it ended up getting stolen out of my car. So I finally just bought one one ebay again, it said it was in "Excellent Condition". When I received it, I turned it on, and the light for the entire screen doesnt light up! If you angle it just right you can see that it is powered up and you can see the desktop is there. If you squint just right you can start to navigate around. I tried to return it to the seller but he won't give me my money back. My question is, is there any "easy fix" to fix the screen so it lights up and I can actually see things on it? Or am I completely screwed?
