iPad Air 2 lỗi không xạc không nhận cable
step 1: put charge cable to measure here, if it doesnt have 5v ->check charge cable. Must be solder, not socket.
step 2: measure the resistance at 2 peaks of wires (yellow frame), data lines. Common problem was recognized one side charge.
step 3: measure at this IC base, if it doesnt have 5v -> tracking to line and lifting it.
step 4: measure here, if it doesnt have 5v -> replace or short lifting the protector of charge (red frame 1) to test. If it OK ->replace.
step 5: replace this IC usb, 5s 5c can use for each other.
step 6: devides weren’t had battery when charged -> try to replace diot and this wire follow order 1,2.
purple text: measure all capacitors (purple frame), if shorting -> isolate and remove.
green text: just take a look at resistances (green frame), dont do anything if it was good, error just happen when devive drop in water and rotten.
NOTE: With ipad air 2, the components on charge line rarely error. Just a small error first at cable, then to USB chip, and direct to IC source frame 2 at last.
