iPad air lỗi xạc và cable
step 1: put charge cable to measure here, if it doesnt have 5v ->replace charge cable. Must be solder, not socket.
step 2: measure this capacitor, if don’t have voltage ->short lifting the transfer circuit voltage charge as line, or measure to red line, lifting the wire (yellow frame) on line.
step 3: device recognize 1 side of charge or doesn’t recognize cable at all -> measure the pair of data 1; data 2 to chip usb, if broke -> lifting the double wire on line; if weren’t broke -> replace chip usb (orange frame); 5s 5c can be use for eachother.
step 4: measure the capacitors (purple frame), if shorting -> isolate and remove.
step 5: take a look at resistances (green frame), error just happen when devive rotten by water or pilling off -> replace same value.
Note: Most of error of Ipad Air that battery weren’t charge. When we replaced IC usb, but it still error -> fully error at IC source 2. Rarely error at diot 1 and wire 3.
