iPhone 5 No sound/mic during calls – iphone mobile hardware strange problem

On January 23, 2015, Posted by , In iPhone, With Comments Off on iPhone 5 No sound/mic during calls – iphone mobile hardware strange problem

Hi,


I have an iPhone 5 64GB that I am trying to fix, the issue is that during calls I cannot hear anything and also the caller at the end cannot hear anything either. I have tested the MIC and Speaker via the voice memo and via the video recording and they all work fine. I have even tried replacing the noise cancelling mic, the charging dock (mic) and the speakers. I have restored the phone multiple times but Along with no luck.
I am wondering where I should start Along with a board level repair, what should I try and reflow/replace first? I have all the equipment to do so at my work.

Thanks in advance for any to be helped you can give me.

    Alright, thanks. I wasnt too sure if that would be the issue as the audio works everywhere else, just not calls.

    I will give that a try and post back title=smile
