Microphone issue board related.

SM-928V

Upon detaching the charging port flex from the board, in order to replace with a new one, I seemed to have damaged a diode/component on the board side near the c-port flex connector. The soft key lights and microphone were n/g thereafter, on any of the 6 charging port flexes, at hand, that i tried. I was able to replace the diode/component on the board and bring function back to just the soft key lights but I'm still having issues with the microphone. Any source for a schematic of the board components and/ or advice for what to do moving forward for device?
