When i lets say playing a song. and wanna sleep the ipod. nothing is wrong. when i try to resume the playback, everything works fine. Just the screen is just showing white and a few dogdy stripes. when i then put it back to sleep and resume it. everything is back to normal. when i sleep it again and resume the white screen with a few stripes come up, and etc etc. anyone know what i should do? i think it been a year or so since i bought it. is there a way to check this?
