Repair of headphone jack after sending phantom power in possible?

Hey,

a few days ago i tried to connect my iPhone to a selfbuild interface, not knewing that there are about 20V phantom power on it. The first two times i got a really bad signal out, but the third time nothing happend. After this i tried to plug normal headphones in, but no output.

The build-in speaker works still fine and headphones get detected, too (volume changes, if i plug them in).

My Question is, if it would work, if i only replace my headphone jack (see here: [연계 제품이 누락 또는 비활성화 됨: IF182-016]) or if something different, e.g. the logic board, could be broken.

Thanks for any hint or solution!

EDIT 02.12.2013:

It looks like no one had this problem before or knows what to do. So I bought the new headphone jack today and will try to fix it. I will report any progress I make, so if anyone else will get this problem they dont have to ask again...

Till then

EDIT 23.12.2013:

Last weekend I changed the Headphonejack and had kind of success. Before the repair no audio (through headphones) worked (I can't remember if the remote control on the headphone still worked, sorry). Now at least the left Speaker works fine, and also the Middle-Knob (Play/Pause) works, but the volume-buttons on the headphones are still broken.

I dont know, if it's the fault of the replacement part (because it was defenetly better after the change) or if something weird happend to the LogicBoard.

I contacted the reseller about the replacment-part, but until now i don't have an answer.

Let's see what will happen next
