step 1: Phone with 100% intact, when we took off, then glued up but the screen wasn’t work -> check the voltage line, it often break the wire (yellow frame), then lifting.
step 2: If it shorting when measured -> isolate capacitors (purple frame) or IC (red frame).
step 3: data line cross the pair of capacitors (orange frame), so cannot measure resistance of socket as well. The capacitors must to replace, do not remove. Take a careful look and measure clear circuit the wires (yellow frame).
step 4: Take a look and measure the resistance (green frame). IF it pilling off or rotten 1 one by water -> replace same value.
Note: Ipad Air 1 often error at the light more than the screen. Most of them were broke the supply voltage wire, because take off the screen without turn off phone.
