If you need help with the headphone jack let me know, I have them in stock and only charge a few bucks to do the work. Also it could not be the headphone jack, could be the wires from the circuit board or the audio chip itself, but most likely it's the jack or the wires, if it was the chip you wouldn't have anything at all period. But let me know if you need just the jack from me, it's 10 bucks shipped. they are stereo but the wiring could be mono, you just have to make sure you wire it right. Best way to do it is to take a picture of it before you take it apart then this way you have something to look at when you put it back together. Talk to you later.
