Speaker volume low! - GSM-Forum

Fabi89 · 11-22-2010, 21:27

Hi,

I've had a series of problems with my iPhone 3g.
1. Digitizer not working, replaced it, now works.
2. while doing that, broke a little capacitor near connector 4 (marked in red) resulting in no charge/sync symptom.
3. while fixing that, broke another capacitor (marked in green) which is part of the homebutton circuit.
4. while fixing that, may have damaged some other parts next to it (marked in pink!)

question: are these parts (marked in pink) related to the bottom speaker?
what are they for?

I forgot to say, my problem now is the bottom speaker, which has VERY low sound! I've already replaced the entire dock connector/speaker/mic-unit and it's still very low volume!

im suprised no one has a solution for this, i also have this problem i changed the entire dock but still low volume did you manage to fix it ??

Yes I have found a solution for it, but that was sheer luck! I couldn't find any diagrams for the speaker circuit, so i just assumed one of the parts i marked in pink (probably the one on the right) had been damaged while soldering the parts for the homebutton circuit (marked green). And that was the case. What did the trick for me was using a medical scalpel to dissect each of the soldering joints. Since they are so tiny, I must've soldered them up.
So basically the problem was the existence of a connection between joints that are normally unconnected.

Let me know if that was your problem too!
