step 1: Measure the resistance here. If lost -> tracking and lifting.
step 2: If resistance was full, but didn’t work -> isolate and remove capacitors (purple frame), or protect diot (orange frame).
step 3: measure here but hadn’t found resistance-> broke straight to cpu, if have -> short lifting wire (yellow frame) or resistance (green frame) too.
Note: Most of data correct volume line of Ipad mini just cross resistances and wire, then straight to cpu, so just need to measure to find error.
