IPhone 3g Top button fix?

[SailorKev85]

Ollo,
I have a say was new 3G which has turned into a "Touch" for me these days and my top button has stopped working but everything else is still great. I have tried taking it apart To see if something was binding.. Problem not resolved, anyone have ideas? or links for parts which might make it work again?

Thanks!!

This is seems to be a hardware problem as you says so take to the repairing shop or change it for another set saving your address book and other contents.

Buy a new power button online and replace it

From my experience, this problem is either caused by moisture having gotten inside the button and causing corrosion, or the ribbon cable has started to get cracks - actually, both problems are ultimately the ribbon cable.

If the phone's silver bezel is starting to separate near the top, it will cause stress on the cable and lead to failure. If that is the case, glue it back together before completing the repair.

The ribbon cable is cheap and easy to find online, but it's a little challenging to replace it. The ribbon cable is attached to a lot of other hardware that must all be disassembled. If you are going to replace it, you should make sure that the replacement cable has the logic board connector already installed - not all do. If it's missing, you can desolder the one on the old ribbon cable and swap them, but it takes some skill and the right tools.

If you want to see if there is some repairable moisture damage, you can disassemble the switch itself and try to clean it. It's kind of "taped" together, so you can carefully unwrap it. The switch contact is simply a metal clicker dome on top of two contacts on the ribbon cable. It it had gotten wet in there, it will cause green corrosion that may be cleaned off with alcohol if you're careful. The traces are very small, however, so the corrosion is usually too far to repair. Make sure you also clean the inside of the clicker dome.

I'm making this sound harder than it is, but I want to make it clear that it can be fixed cheaply (less than $20), but the repair may be above many people's skill level.

i agree with Tanbam that you can do it yourself inexpensively.
i also agree that the repair may be above many peoples skill level...it takes seasoned technicians over an hour to do this repair. The part you need is called the headphone jack flex cable. That part controls not only your power button, but your headphone jack, volume, and vibrate. Truth is that you can have a professional repair for around 40......why run the risk????
