boardview Motorola Droid Turbo 2 (XT1585) - 84016327001 REV A - Call microphone fails to function after charge port replacement

[phreakheaven]

After charge port replacement, the lone microphone (for phone calls) no longer functions. I've replaced it with five mics pulled from other boards, but it just sounds like white noise every time. I have fixed this issue in many other phones before, including several of this model device, with almost no issues. I am using both preheater underneath (at 183-200C), and hot air above (250C max) for removal, and installation. Currently, I have a mic that I sliced from a donor board using a blade, and that is now curing with conductive epoxy, as I would like to rule out heat destroying the replacement mics. I am searching for the boardview to this device, as I have no idea whether another component in the circuit is the culprit, instead of the mic itself.

 

I found the schematic here:

However, I cannot download it yet, as I am new to this forum.

 

I would prefer a boardview to trace the pathways, but a schematic would at least help get past this point.

 

 

Thank you for any assistance you can offer!
