iPad air chạm áp sơ cấp part 2
step 1: measure here, if shorting -> it is the shorting of primary voltage part 2.
step 2: This IC will be heat but not shorting. Short lifting it to red colour and Use shorting tracking method in begin part to find where was shorting and tried to isolate heat area. Remove slowly capacitor, diot and IC of heat area til shorting is over.
NOTE: At this part 2, it doesnt shorting at permanent point, so try to track yourself. With Devices make icloud by chisel HDD but decrease battery -> check this IC supply voltage (red frame), it often shorting.
