iPhone rear camera can not be activated? Give rear camera replacing a try and it doesn’t work this time? Well, you’d better start with logic board solution now. With this iPhone 6 camera not working case analysis, REWA demonstrates a high-level logic board repair technique that can definitely surprise you.

iPhone 6 Camera Not Working Case AnalysisTap “Camera” icon and enter into camera mode, the rear camera cannot be activated. Switch to front camera. It works normally.

Let’s replace it with a new rear camera at the beginning. Disassemble the phone, detach battery and then remove the display assembly. Take down the rear camera and replace with a new rear camera.

Get the display assembly buckled and connect the battery. Then power on and test. The rear camera still cannot be activated.

Remove the display assembly and take down the rear camera. Measure the rear camera power supply voltage. The power supply voltage value is normal.

Then, measure the resistance between rear camera connector and grounding. The resistance value of pin 30 is 303, which is abnormal. The reference resistance value of pin 30 should be 537 or so.

Pin 30 works as the activating signal of the flashlight. It is also connected with pin E3 of flashlight IC U1602 via FL2322 and C2300.

Take down the logic board. Then attach the logic board to PCB Holder. Then take down capacitor C2300 with Hot Air Gun at 320℃. Then measure the resistance between pin 30 and grounding again. The resistance value of pin 30 is 300, which is abnormal.

Then we can draw the conclusion that IC U1602 broke down.

Take off the shield plate of CPU with Hot Air Gun at 320℃. We can see that the flashlight IC is right next to CPU, and to protect the CPU from high temperature when removing IC, we need to cover the CPU with the detached shield plate.

Blow with Hot Air Gun at 320℃ and pry off the flashlight IC with sculpture knife. After that, clean tins on the bonding pad with Soldering Iron. Then clean again with PCB Cleaner.

Once the logic board is cooling enough, measure the resistance between pin 30 and grounding again. The resistance value of pin 30 is 0, which is normal.

Apply some BGA Paste Flux to the bonding pad and align the new flashlight IC to the right place. Remember to cover the CPU with the detached shield plate. Then solder the new flashlight IC with Hot Air Gun at 320℃.

Once soldering is finished, wait for the logic board to cool for 5 minutes. Then measure the resistance between pin 30 and grounding again. The resistance value of pin 30 is 518, which is normal. Which also indicates that the fault has been cleared.

Get the logic board assembled and connect the battery. Buckle the display assembly and power on. The rear camera can be activated this time. Rear camera fault repair finished.
