I am having the same problems too with the screen sensor. I have a ipod that is a five generation. I've tried resetting the ipod but that doesn't change a thing. I also pressed the sleep/ wake button and when the button said " slide to power off" I couldn't because the screen sensor isn't working. I was so desperate I even tried wiping off the screen with a cloth but that didn't work. Please if you have any other ways to fix this can you comment ? Thanks....
