Dead after Dock Connector replacement

Hi all,

this is what happened: I tripped over my sync cable while my iPhone was charging and it fell to the ground. After that, neither the home button, the microphone, the bottom speaker nor the dock connector were working (it was neither charging anymore, nor did my computer take notice it being plugged in). Everything else was still perfectly fine.

I ordered a new dock connector (meanwhile, the battery had depleted) and replaced it.

However my iPhone has yet to show any sign of life. I've been charging it for days with the wall charger, tried turning it on, rebooting it etc.

Looking at the old dock connector or the logic board, I can not see any damage.

I'm at a loss. Any ideas?

it doesn't say which of the four pins is + and which is - , and I don't have a multimeter.

w00t, it worked! It's alive again!!!

OK, after some serious googling I found that the uppermost connector (holding the iPhone in portrait, the dock connector facing the bottom) on the battery terminal is + and the lower most is -. Gave it a 5-10 sec. charge from a 9V battery, assembled it and then – the moment of truth – plugged it in. And the screen came alive, showing the good ol 'I'm out of juice' pic. Hooray!

Hi teilerdoerden,

I suggest that you - like oldturkey03 mentioned - test a different sync cable. There is surely a friend around who can borrow you his before you have to buy a new one.

By tripping a tiny cable like the sync cable, sometimes a wire can break inside the cable or in the interface housing where the soldering joints are. The pulling and ripping forces in such a moment should not be underestimated.

In addition to such an electrical interruption, wires can also create an electrical short. It seems to me that through such a brief impulse, the dock connector unit might have been electronically (but invisible to the eye) ruined.

The use of a different cable would initially narrow down other sources of error.

Steffen

Update

Have you tried a different cable as well?

Thanks for your answer, but I have already tried that.

have you tested the battery with a multimeter? it won't charge if it's less than 2.2mah.. you can give the battery a jump start with a 9v battery, make sure it's disconnected from the logic board before fiddling about.

Update

@pollytinop: I need more precise instructions, e.g. how to connect the battery, what kind of batter etc. Do you have a link for me?
