Hello

I got iphone 3gs with microphone signal problem. Microphone don't work well (buzz) and it too from headset mic and bluetooth headset mic too. I was replace microphone but nothing happened. I also reinstall ios from 4.0.1 to 4.1 and nothing too (((

Before i have 2 problems - audio jack and microphone signal, but i was repair audio jack.

So i was think that damage was in the motherboard perhaps somebody could give some working tips to solve this problem?

Thanks a lot in advance

I'm not sure about how you call a microphone. Do you mean speakers or earphones?

have you any sound from the phone at all? either on loudspeaker or earpiece during calls?

have you tried opening voice memo app and recording your voice then try play back?

I would've suggested returning phone to shop as may be under warranty.Otherwise I'd try replacing dock assembly or checking connector 4 pins. I think James bond also had this problem and it was 2 small (tiny) ?capacitors beside dock connector on motherboard. Have a look in that area. Search James bond at top to find his solution.

这个答案有帮助吗？

No USB Connection after I broke little SMD element near connector #4!

This is link to photo of part for noise reduction ( beside dock connector) I haven't had time to go through all his answers but James bond says somewhere it can be fixed with just fine wire and solder.... Take a look at his answers and vote his answer up if it helps!!
