Water Damage - home button no longer works
A friend fell into a lake while holding an iPhone. Everything works fine except for the home button. I've disassembled it and tested the button mechanism itself and found that it works fine. Resistance across the button's two contacts drops to zero when I press the button. So I suspect that the failure isn't in the button mechanism. I found the contacts where the button connects to the board and tried bridging them to simulate the effect of pressing the button and closing the circuit. This has no effect. I didn't want to tear down any further without more info. Any help would be greatly appreciated.
Is dit een goede vraag?
