step 1: Lost one side light, you just need to measure the model resistance on this line to model main to know which lines were error -> fix it to line.
step 2: If shorting -> gradually isolate the capacitors (purple frame) on shorting line.
step 4 (orange): the resistance were incorrect when measured at step 1 ->replace diot and wire (orange frame) on incorrect line 1 or 2.
step 4 (green): take a look and measure 2 sides of resistance at break light line, if error -> short lifting, don’t need to replace. If shorting ->remove capacitors (purple frame) on shorting line.
Note: Most of Ipad Air often lost 1 side light. In case, lights fully broke -> most of error at IC source (blue frame). Lost 1 side light -> 99% error at diot (orange frame) on error line.
