iPod iPod Nano 1st Gen - Click wheel not responding

[SteelBlueTJ]

I have an older iPod Nano 1st gen. The click wheel won't respond at all. I can turn the iPod on by switching the hold button or by connecting it to USB, but the click wheel is totally dead. It won't scroll or anything. But what's weird is I can still reset it by holding down center and menu. If the click wheel went bad, how come I can still reset it? how difficult is it to replace a click wheel or is it even worth the hassle for a 1st gen nano? Thanks

The hold switch might be stuck on preventing the firmware from allowing anything to register except for the built in reset.
