step 1: Measure the resistance of sockets. If lost -> tracking and lifting the wire (yellow frame) on line.
red text: headphone (HP) was unrecognized or shorting -> check HP detect line, lifting the wire (yellow frame) or replace the resistance (green frame) on line. It still didn’t work-> replace audio code.
white text: HP left, HP right cross the wire (yellow frame),then straight to audio code, so if lost resistance -> take off audio and measure clear circuit.
orange text: the volume button of HP was error ->check this 2 lines.
blue text: Micro recorder on HP was error -> check the capacitor (orange frame) and resistance (green frame) near IC audio code ->replace same value, remove if didn’t work.
Note: HP of Ipad mini offten error by the wire (yellow frame) near socket was pilling off or IC audio code error, rarely mise errors at other components.
