It looks like there is scanlines/interlacing and there are really weird purple vertical lines. I have shut it completely off and turned it back on but it's still there. It also looks sorta greyish and changing brightness does not help. It was cold here recently (around -30) and he brings it out to work some times. It is running iOS 4.2. Any help appreciated.
