We received an iPhone 6 Plus. The customer said that after turning on the rear camera of the iPhone, the display is black, there is no image, and the iPhone rear camera is not working properly. Then he switched the iPhone to the front camera, the effect is very good, the iPhone front camera can take pictures. How to fix this phenomenon?

The iPhone 6 Plus rear camera doesn't take pictures, but the iPhone front camera can take pictures, which means the public control part is normal, we only need to look at the circuit camera only for the back of the iPhone.

Firstly, we need to disassemble the iPhone 6 Plus. Use JM-P01 Phone Teardown Toolkit to disassemble the iPhone 6P, and then remove the iPhone display assembly.

Replace the new iPhone rear camera. After replacement, the iPhone rear camera still not working, the failure is the same. Now we confirmed that it's not the problem of the iPhone rear camera, we need check circuits.

Use digital multimeter to measure the power supply of the iPhone rear camera, when measured the 34th pin, we found it has no voltage.

Open the ZXW dongle to check iPhone schematic diagram, we saw that this circuit is the power supply of a 2.8V, it's supplied by camera LDO chip U2301.

Use the QUICK 861DW hot air rework station to remove the camera LDO chip U2301 and install the new U2301. After the installation is completed, measure it again with a digital multimeter, and the measured data is now normal.

Finally, assemble the iPhone 6 Plus, turn on the iPhone and test it, now the iPhone rear camera works, it can take photos and videos.
