What To Do When Your iPhone 6 Camera Not Working

Follow this guide to fix the problems of iPhone 6 camera not working.This guide offers you a very detailed logic board repair solution of the problems which the iPhone 6 camera not working and the flash is failed to be turned on. Now let's follow the leads to find out what is the real cause of it.

iPhone 6 Camera Not Working Example:

iPhone 6 camera doesn’t work and flash is failed to be turned on, If your iPhone 6 camera could take video while no photos can be taken and the flash is failed to be turned on, you can find the logic board repair solution from another ariticle "How to Fix Camera Failure on iPhone 6_CPU Repair".

Failure Phenomenon：

The camera of iPhone 6 is not working, it is failed to turn on the flash as well.

Maintenance Procedures:

This type of failure is generally due to the flash damage, so check and repair the flash directly. Firstly, we should measure the power supply of the flash. After checking the circuit diagram, we would find out that the flash power supply is output by U1602, as shown in Pic 4-23. The physical location of the U1602 is shown in Pic 4-24.

After measuring, we find that the working voltage of the flash power supply chip U1602 is normal. By analyzing the U1602 circuit diagram, we know that the flash power supply chip U1602 needs to be controlled through the 1²C bus (see Pic 4-23). Then we remove the flash power supply chip U1602 directly and measure the ground impedance value of E2 pin, D2 pin 1²C bus pad and would find that the ground impedance value of E2 pin and D2 pin is infinite. It illustrates that the 1²C bus of the flash power supply chip is disconnected. This bus is also connected to the back camera base, the ground impedance value measured in the back camera base is normal. We could judge that the layer of the flash power supply chip U1602 pad is disconnected. Then directly fly line from the back camera connection seat to the flash power supply chip U1602 pad and install the U1602 chip, as shown in Pic 4-25 and Pic 4-26.

Finally, Installing the phone, booting into the system and testing the flash and camera, the function is normal, the phone is fixed.
