step 1: Measure the resistance at base mic bias, if lost -> tracking to line and joining wires (yellow frame) on line.
step 2: Bases mic n,p cross the capacitor (orange frame), so when measure doesn’t have resistance, just measure for clear circuit. or measure 2 sides of wire (yellow frame), if break ->joining it together.
step 3: the capacitors (purple frame) if shorting -> remove.
step 4: the capacitors (orange frame) error -> replace the same value, do not remove.
step 5: replace audio code.
note: back camera shooting video without sound, remember to test carefully line of power button before fix main. At main, the common problem was break resistance (yellow frame).
