iPod classic is hung playing tune from yamaha RX how do I get it back. Display shows a apple but will not close pwr off or reset. Anyone have any idea how to clear the problem?

If the iPod is "stuck", then do not leave it plugged into power. All that will do is keep it "stuck doing whatever it can't do". Unplug it and leave it to one side, eventually the battery will run down. Once it's fully run down, recharging it should also reset it.

• So, if the display is permanently on, just leave the iPod until the battery runs down and the display goes bank. Don't sit there waiting and then plug it in the second the display turns off, all that will do is keep the iPod stuck doing whatever it's trying to do. Leave it for at least two days. Only then should you plug it into power to recharge.
• If the display is already blank, but you can get no response from the iPod, leave it for another 24 hours and the plug it into power to recharge the battery.

When the battery is fully drained and you plug the iPod into power, there will be no response from the iPod for anything up to thirty minutes. After that, the iPod will begin to reset. Let it do its thing. In fact, leave the iPod until it is fully charged before trying to use it.
