My click wheel and power button is unresponsive

Here's the best answer I've seen on this issue: it seems that there is some design flaw on the the new curved casing on the 4th gen. i've been reading thru different posts and this seems to be a recurring problem and needs to be addressed by apple. the board/clickwheel after a lot of use loosens up and creating some form of unstable contact, a solution i found is by adding a firm backing to it. i did this by inserting a piece of thin plastic (thin old credit card would do) between the board and the aluminum casing on the bottom end of the iPod. tried this with 2 of my iPods and it worked. of course you need to take the bottom plastic cover and the aluminum connector support with the 2 screws first.

Why has my iPod click wheel stopped working?
