A portion of the screen, almost half, has this problem. It flickers somewhat and keeps temporary afterimage whenever what's on the screen changes there are also black lines every other pixel. This seems to be somewhat affected by temperature and when it's warm enough these effects almost completely stop.
Anyone know what could be causing this? Any change this could be fixed by anything less than replacing the entire screen? I'm tempted to try re-seating the digitizer connection but I don't have any tools.
