How To Repair iPhone 6S White Apple Failure
The customer sent us an iPhone 6S, the fault described is that when the Apple logo is launched, the iPhone screen turns black, and sometimes the iPhone 6S can enter the IOS system.
According to the fault description, it seems to be a problem with the iPhone Nand flash, but it is not sure, so we need to flash the iPhone 6S to check the location of the flash progress bar.
For the first time, iTunes will report a 4014 error when the first flash progress bar is completed. In this case, this is not a problem with the iPhone Nand flash.
Based on maintenance experience, we know that a damaged external configuration can also cause this error. Take out the external configuration, just brush the iPhone motherboard, but the problem still exists.
The co-worker feedback that the iPhone lighting cable has some problems, we need to flash the iPhone 6S for several times. So, we decided to flash the iPhone again. In this time, the flash process is successful. But we don't think the problem was solved, because the customers also said the iPhone 6S can be entered the IOS occasionally. Activate the iPhone and test the functions to check if they are normal.
After testing, all functions tested are normal, it's so weird, now we are going to recharge it. After half an hour, we test it again. The iPhone 6S has no response when we press the iPhone power button, the iPhone display screen is black, but there is a backlight.
The iPhone display screen is black when it in charging, is it the problem of the charge tube? But the charge tube won't cause this trouble. We suspect it's problem of the iPhone USB IC. Replace the iPhone USB IC, and then charge it, test it for 1 day, all works well, the failure has been solved.
