iPhone 5C earpiece problem - GSM-Forum

easyfiks123 · 07-13-2016, 13:45

Hi,

Ive tried searching for this solution but i cant find any.

I've repaired 2 iPhone 5c (screen replacement) and after the repair both the earpieces stopped working. Can't see anything wrong on the mainboard.

I've looked online and some people have the same problem but i have yet to find a solution.

Ive tried several earpieces, front camera flexes and new screens. Seems to be a problem with the mainboard itself.

Would changing the audio ic maybe work? Even though the sound on the phone works fine.

Thanks in advance

Too late now, I suppose, but I would check FL51 and FL52 for continuity (to the left of connector J1). If faulty, either replace or jumper. I would try that first, before replacing the audio ic.

You mean changing the audio ic will damage the phone @ mogs

No, it won't damage the phone, but it's a lot easier to check the filters first. The audio ICs aren't cheap, so you don't want to be replacing it if you don't need to.
I found this out myself the hard way! I had the same earpiece problem, so I swapped the audio IC - cost me £8.50 (GBP) - but it did not fix it. Only then did I realise that FL52 had gone open circuit, so I jumped it and that did fix it.
So in my case, I did the expensive and harder option first and replaced a perfectly good audio chip! I try to do the cheaper and easier things first, now.
