how can I get my Ipod Classic 80GB repaired

Hello sailinmum,

Welcome to the Apple Support Community.

Unfortunately Apple classifies the iPod classic 80GB as a "Obsolete Product" as they stopped selling it over 7 years ago.

If you needed your iPod repaired you would have to find a 3rd party service centre that has parts and expertise on how to fix an iPod but do note Apple is not responsible for any damage caused by a 3rd party.

You can read the document I referenced below;

Obtaining service for your Apple product after an expired warranty - Apple Support (CA)

I know this isn't the answer you were hoping to receive but I hope this helps,
