No audio or audio controls on prior work
I have received an iPhone 7 that has been worked on before (badly). The faults were two fold, the first was no rear camera, this was the LDO near the Wifi IC which has been repaired by a previous tech. This tech also did an audio IC repair but has made a bit of a mash of it. ALL of the Pads along the top edge are missing. I have jumpered these are ALL of the diode readings are good without the IC on. I have replaced the Audio IC 3 times with new chips and still the problem exists. I have also replaced the speaker AMP next to tristar and the all diiode readings are good too.
The problem is there is no audio, no mic input from the voice memo app and the volume buttons do nothing. Also there are no sw volume controls. I have also restored IOS twice.
I am thinking that something is screwing with the I2S bus and before I start replacing the other amps and Maggie (which I have never had to do before) I was wondering if there are any other suggestions? All other features of the device seem to be working fine. (Oh and I have tried a different housing as well, so the fault is on the logic board
Questa è una buona domanda?
