Fixed: iPhone 7 Camera Failure


It's really annoying that you are unable to use your camera in a normal way? You also meet the same status? iPhone 7 camera cannot be opened? it's ok for taking videos but it fails to take pictures? or it's ok for taking pictures but unable to save in cell phone? If you have encountered one of these failures, please follow the steps to have your repair operation!


Use a Fluke 15B+ High Performance Digital Multimeter to test the power supply status as following (When the iPhone 7 camera function is on and the screen lights up):

After turning on the iPhone 7 device, the PP1V8_UT (1.8V), PP3V0_UT_SVDD (3.0V) can be measured, however, the PP2V8_UT_AF (2.8V, PP2V9_UT_AVDD aggregation voltage) (2.9V), PP1V2_UT_VDD (1.2V) these three circuits of power supply only can be measured when the iPhone7 camera under good state, the PP2V9_UT_AVDD circuit power supply is provided by the U2501, the U2501 is very easy to cause camera working abnormally. The best solution is to take the U2501 off and short connect by jumper wire to solve the problem.

PP3V0_UT_SVDD (3.0V), PP2V8_UT_AF (2.8), VPP1V2_UT_VDD (1.2V) is sent to the camera interface J4501 respectively through inductance FL2500 FL2502 FL2505 FL2506.

These inductors are easy to damage, resulting in failure to take photos. First, measure the resistance of the 5 circuit of power supply to the ground, exclude the failures of broken circuit or short circuit. Check FL2500 FL2502 FL2505 FL2506 and short connect U2501 by jumper wire.

Note: the system will automatically turn off the camera function when the iPhone hardware is abnormal. If you can't take photos after restoring the power supply, you can erase all the data and activate it again.

Morover, iPhoneflash power supply IC damage will also cause no camera function, can take videos but unable to take photos, can take photos but unable to save them. If you encounter this problem, just replace a new iPhone 7 flash power supply IC will solve the problem!

iPhone 6 Display Failure after Replacing LCD

The iPhone 6 display is black after replacing LCD. After checking, the diode data of display socket is normal and all power supply for iPhone display IC  output is normal. Testing by  DC power supply , we find the iPhone current is abnormal. When press the iPhone power button, the boot current is obviously large. The current reached 100mA when press the power button. After remove the display tube, the current still the same, which means there is a short circuit. Measure the voltage output of each circuit of power supply with Fluke 15B+ Digital Multimeter , then surprised to find that there are really short circuit places. LD010 is short circuit; we suspect that the filter capacitance on the circuit has been penetrated. After remove the iPhone power control IC , we found it is ground short circuit. Open the WUXINJI Dongle  to check the iPhone schematic circuit, we found that this circuit is the display card image transmission MIPI data bus power supply. CPU brea...

Solution: iPhone X Won't Turn On

According to the customer's description, the iPhone X would not turn on after it drop accidentally. Then the cell phone reports error 56 when restore it. How did this happen? Let's test and repair step by step. Since iPhone X motherboard 2 layers are connected through the middle column, the solder points are very easy to get dropped. so we guess that the solder points from NFC chip to the CPU part have fell off. Disassemble the iPhone X by iPhone opening tools , remove the upper board off the main board, when separate the main board we see there is a row of points have fell off. Check 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. Then the tin of the middle column is repaired by iPhone X BGA reballing ste...

Guide: iPhone 7 Plus Camera Fault Repair

iPhone camera failure is common for most of cell phone repair technicians, today, we're going to fix iPhone 7 Plus camera. According to the holder's description, the front small camera is normal while the rear camera fails to take photos, when turn on it, the iPhone 7 shows black screen. Let's start from easy repair operation: directly replace the iPhone camera to have a test.  Note: Pay attention that two camera are connected together. When disassemble the iPhone 7P rear camera , you need to pry up from the left side.  The fault is same as before after replacing a new rear camera. We tested before, the iPhone 7P double camera is rely on the bigger camera to get image, as shown in 15-5-1, the corresponding part on iPhone 7P motherboard is J4501 pin, the resistance value is normal after testing with Fluke 15B+ digital multimeter , it reminds of us that iPhone6 Plus also encountered this phenomenon, the power supply part has some problem. By checking on  WUXINJ...
