iPad mini 1 lỗi nút home
step 1: Measure the resistance of socket. If lost -> tracking and lifting the wire (yellow frame), or replace resistance (green frame) if lost or broke.
step 2: if home button sometimes shorting -> isolate and remove capacitor (purple frame).
step 3: watch this resistance (green frame), if rotten -> replace same value. Measure voltage at red side, if lost -> lifting to red line.
white text: finally, still didn’t work -> take off Ic source to measure here, if resistance hadn’t found -> broke to cpu, if had -> try to replace IC source.
Note: Home button of ipad mini was on the line beading to sensor. With devices replaced sensor or took off sensor, sometime lost the insulate surface or shorting home button to side. Careful here is OK. Main rarely error.
