first of all - forget the idea of bringing it to apple - they don't care.
there is something you could do:
disassemble it using the logicboard guide for your model
you will find some white/greenish residue on the logicboard
get isopropyl alcohol (>90%) and clean those parts carefully with a soft paintbrush - the residue is conductive and shortens the parts - thats why the iPod won't work.
let it dry after you're done and then reassemble it, if it's not powering on, try to charge it
