Brand new iPod Touch, won't charge!

Hi there,

Have posted this under another topic but hope to get some more exposure here.

Just as a disclaimer, I work for a retail store in New Zealand. Have taken a returned iPod touch home to try and fix, but am stuck! This iPod still belongs to my employer however, needs to be restored to a re-sellable condition.

Basically, the iPod touch will not charge. It is forever stuck on the 'no charge' screen with the red battery symbol and the lightning bolt at the bottom. This is when it is plugged in (have plugged it in to a PC, my Mac and wall charger). When not plugged in, same symbols appear except with a plug symbol, pointing to the lightning bolt.

When plugged in, the iPod doesn't show up in iTunes or Disk Utility, same on the HP PC laptop I also tried it on.

I put the iPod into DFU mode and restored it to the latest firmware with iTunes on my Mac. However, once the iPod has finished restoring, iTunes tells me it will show up after rebooting but once the countdown has finished, the same stupid 'no charge' symbols appear.

By the way, this iPod has been left charging on two different wall chargers overnight, I have tried restoring it several times and still to no avail.

Any help would be greatly appreciated!! I am totally stumped.

Cheers!
