Received a iPhone 6 with reboot failure, how should we repair
The first is to clamp for a test by DC power supply,it is found that the current has been rising repeatedly or dropping 100 ma.
Based on our previous repair experience, we judge the 2 IC2 bus control through the display D2, D3 is pulled down or short circuit, this kind of situation is very common, these two I2C bus are also called light control, if the current changes, it's possible lamp control damage; If the current is fixed, it's possibly display damage.
Use the QUICK hot air gun to remove the CPU shield and observe it under Trinocular Stereo Microscope, we can not see any problems from the surface, so we continue to blow down the light. Picture 1
After removing the light control, connect DC power supply to test again, we found that the current is normal now, so it is judged that the light is damaged, so we replace a new one directly. Picture 2
Replace a new light control, install the iPhone 6 to test, we are able to turn on it normally, and the light is normal. And there are no any problems for the other functions. The ‘iPhone won't turn on problem’ is successfully solved now!
