iPhone 3gs sound problems – lot of problems ! its some previous iphone pone problem
Recently I picked up a 3gs for under $20. The seller told me that everything works except the audio. To my surprise, upon unboxing it turned out that audio works just fine along Along with everything else. Or so I thought, but the wifi antenna couldnt find my router.
After inspection I tried to charge it and it worked just fine but as soon as I plugged in the charger there were no sounds anymore. When I disassembled it and cleaned all the dust out Along with alcohol (and there was a lot of it) I noticed that the shield covering the audio ic was a little bent indicating that it was opened before. That made me think that maybe the audio ic could be the culprit of the problem but that still doesnt explain how the audio worked perfectly fine before I plugged in the charger.
As far as I know the dock connector, microphone and speaker are all in one assembly. Having that in mind if I disconnect the unit the headphone jack shoud still be able to play sounds. But it didnt.
I also tried applying pressure on the audio ic but that didnt to be helped either.
Since Im out of ideas, does anybody have any suggestions?
