Not charging, no usb connectivity
I have encountered quite a few ipad air and air 2 which I am unable to repair. Unit still doesn't detect charger and no usb connectivity even after changing the charging chip and the lightning port. Some boards will detect charger when it is plug-in while the unit is OFF but failed to recognized it again when you unplugged and plugged the usb cable again. I suspect that the PMU is defective but replacing it is beyond my capability. Any help and info is greatly appreciated! Thanks!!!
