No audio after charging port replacement, possible ESD damage?
Hi eveyrbody, today I was replacing a galaxy s5 charging port flex cable. Before closing the smartphone I tested it and I noticed that suddendly I had no audio from the back speaker and from the front speaker also. I said strange, after having removed the screen I had audio, I heard it from the booting screen of the phone. Now the only thing I'm thinking is: is it possible that I killed an IC, a filter, a resistor or a capacitor that was in charge of all the audio of the smartphone by an ESD discharge? Yeah, I don't work in an anti-static environment now, I'm gonna implement it in the near future I promise. That's the only thing I'm thinking right now because after having excluded a software disease I don't know what to think. Thanks in advance Roberto
