| I found one problem. Check if one of the mic pad is shorted to the ground then the problem is not the mic but is the EMI Filter near the power supply it is responsable of the bottom mic. The other pad goes under the power supply. This motherboard (SE) are very difficult to work, as i needed to use rework station and solder iron to take off the cristal IC....}
This time i was lucky as i have one dead k750 phone and i took the cristal from it. Does anyone have idea how to make wires on this IC as i feel like this is gonna be very frequent problem....
