This morning I noticed my phone has several light grey horizontal lines on the display, that don't go away when I change applications, or restart the phone. They don't rotate when I rotate the display - it reminds me of when we were warned about images "burning" into the display of PCs, hence screensavers.
Last night I went to bed with Winamp running while the phone was charging, and I have noticed it doesn't always seem to go to screensaver/black with Winamp. But the lines don't seem to correspond to anything in the Winamp UI, so...I have no idea.
What else should I try to get rid of these lines?
