I bought a nokia n97 about a year ago & it has been perfectly fine. I have dropped it a few times but nothing ever happened to it. Today I left it on my counter & came back only to see that I couldnt even see the screen. Everything is distorted by these moving lines. A few screens are perfectly normal, some are able barely able to be read, and some are completely messed up. How can I fix this?? Please help me
