iPhone 6 Plus black screen can’t open the machine brush error 4005 repair
Machine model: iPhone 6 Plus
Malfunction: the mobile phone no display can’t be turned on, and 70mA stop at Fixed current is powered on.
Customer’s description: originally, the touch was repaired. The front Camera BTB connector fell off during soldering. After the test Camera failed to work, it blew on fingerprint BTB connector and then it didn’t display. CPU Camera said it was a little drum.
Maintenance process: the single board is powered on directly, the current is fixed at 70mA, and the detection buses V RAM and Update System are the first to wait for an error 4005, and it is judged that Diode value is normal has a problem. Redo CPU Update System reported an error, and then replace Diode value is normal directly into the system.
