iPad mini 1 lỗi liệt cảm ứng màn hình
step 1: Measure the resistance of sockets. If lost -> use zxw to tracking and joining the wires (yellow frame). Most of them were broke at the wire (yellow frame).
step 2: measure the capacitors (purple frame) on voltage line, if shorting -> isolate and remove.
step 3: glue sensor to measure here, if didn’t have 5v or weak -> replace diot wire (orange frame) to order 1-2, replace IC source.
step 4: glue sensor to turn on source here, if didn’t have voltage 1v8 -> replace IC supply voltage (red frame).
step 5: replace oscillation
green text: watch this resistance (green frame), it easy rotten by water.
Note: Sensor of Ipad mini were beading a circuit grid independent. Shoud be test carefully. Error sensor by main was started at IC source.
