Bought the iPod Classic in 2014 right when it was discontinued. I've never dropped it, the thing barely has any scratches, its pins are all intact, and everything is fine from the outside. I hadn't used it for about a month, during which time it was charging on the nightstand. Decided to use it today but the thing is dead - a completely black screen, nothing happens when I plug it in anywhere, reset doesn't work, and the Genius Bar couldn't do anything. It's not recognized as a drive on the computer and doesn't show up on iTunes Any suggestions? Is there a way to tell if there is an issue with the hard drive or logic board specifically? Or is it an issue of it being in the charge for too long. Help! And thanks!
