Will not turn on or charge
Black screen and Will only show red battery indicator when plugged in To charger and will not turn on
Sometimes devices can take up to 2 hours on charge to turn back on. If this does not do the trick then try the following:
Press and hold both the Top button and the Home button for at least 10 seconds, until you see the Apple logo.
If this also does not help then your battery is more than likely bad and in need of replacing. If you have an amp meter that you can plug a charger into then you can at least test to see if it’s drawing amps. This should help diagnose the issue. Amp/Voltage testers are really inexpensive on places like eBay.
Also on iPods it is common for the power buttons to become damaged and unusable.
