How to looking for iPhone 6s Camera Part Repair

The iphone camera is very important in our daily life, such as traveling and taking pictures, capturing some good moments.

Sometimes front or rea camera can't be used normally, it is a common problem of the mobile phone.It's sad. If the same problem is found on your iPhone 6S, how should you diagnose and repair it?

1. Rear Camera Repair

First, we take out WUXINJI schematic diagram and read the power supply circuit diagram of iPhone 6S. There are three circuit of power supply in total:

One of the circuit is 1.2V PP1V2_CAMERA from the power supply IC, the 1.2V power supply was sent to rear camera interface J3200 through inductor FL3201, if the voltage is not sent to the iPhone 6s rear camera interface, it is generally caused by FL3201 corrosion, use jumper wire to do short connection will solve the problem.

The second circuit is 1.8V from the IC power supply, 1.8V power supply was sent to FL3220 rear camera interface through inductor FL3220, and inductor 3220 is easy to get corrosion damage so that 1.8V is not able to be sent to rear camera interface, use jumper wire to do short connection will solve the problem.

The last circuit power 2.85V is supplied by U3200, the U3200 output voltage 2.85V was sent to rear camera interface through inductor FL3202, the rear camera fault is mostly caused by U3200 damage so that 2.85V is not able to be supplied to rear camera, the 2.85V voltage is not able to be tested by Fluke 15B+ Digital Multimeter until there is resistance C3200 when taking photos. It's not easy to measure because of narrow place, so we can connect an enameled wire on capacitor C3200 for convenient measurement. Turn on the camera and test it immediately. If it is a good handset, it can measure 2. 85V voltage, if the 2.85V voltage is not measured when the camera is turned on, it indicates that U3200 is damaged. This situation can be also solved by phone repair jumper wire short connection.

2. Front Camera Repair

If the front camera can not work normally, check the FL3100 FL3102 FL3104 short connection. Re-stall or replace the iPhone 6s power IC.

In addition, the flash IC damage will also cause failure to take photos or videos. Replace the iPhone 6s flash IC can fix the problem.

Slove iPhone X Won't Turn On

Image
Customer delivered a iPhone X and described the fault is not to boot after the phone drop accidentally. It reports error 56 when restore the iPhone X. How to repair this fault? Because iPhone X is the two board connected through the middle column, it is easy to drop the point. It may be that the solder points from NFC chip to the CPU part have fell off. Take apart the iPhone X by iPhone Screwdriver Repair Tools , take the upper board off the main board, when separate the main board we see a row of points have fell off. Picture 19-3-1 Look at the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56. Picture 19-3-2 Then the tin of the middle column is repaired by iPhone X BGA reballing stencil , and the AP part is welded bac...

IPhone 6P Front Camera and Distance Sensor Fault

Image
Received a iPhone 6 Plus, the customer said that the front camera can not be used, and the distance sensor has problem too. The two failures are concentrated on the front camera flex cable, which is likely to be caused by the damage of the wiring. First, we have to eliminate the possibility of the external parts fault, then consider the motherboard problem. Remove the screen assembly and replace it with a good one, we still can't turn on the front camera and use the distance sensor. Disassemble to measure the ground resistance of the front camera seat of J1111 by Fluke digital multimeter , it is found that several pins are infinitely large, and the related inductors are loose when touch with the pen. It seems that the small components are pseudo welded. 19-1- 1 Remove the motherboard and observe it under the Trinocular Stereo Microscope , we can see that the touch was repaired before. 19-1-2 The back of the sub touch chip U2402 is the front camera seat J1111, an...
