Solution: iPhone 6 Charging Failure


Have you ever encountered charging failure on your cell phone before? We received a iPhone 6 with the same failure. Before repairing, we need to diagnose the reason. In this article, you'll get the best solution.

The iPhone 6 was no response when charging, and there is no charge symbol displayed.

Observe the iPhone 6 motherboard under microscope, it is a perfect board, the iPhone charging flex cable is good, and the resistance value measured by Fluke 15B+ Digital Multimeter also is no problem.


Since we didn't find the problem after measuring, we judge the iPhone U2 IC might be damaged. Use QUICK 861DW hot air rework station to remove the iPhone U2 IC, and then replace it with the new one.

Measure the resistance value again after replacing the U2 IC, the data is normal. So we test the iPhone charge function, the fault still there.

Now remove the iPhone charge tube, and then measure the resistance value, we found the G3 pin is no resistance value.

Check iPhone schematic diagram in the WUXINJI Dongle, we know that the G3 pin is I2c 1 bus, the G3 pin is disconnected, so the iPhone charge tube not working, no resistance value means disconnection. We can fix it by welding the jump wire.


Closest to the iPhone charge tube is the vibrating tube, we weld the jumper wire between them, and then install the iPhone to test, now the problem has been solved.

Tips:

In the maintenance process, if you do not confirm the fault part, you need to change the IC, we can also measure the resistance value of the pin, so even after the replacement of IC, the problem still exists, but you can confirm that the place of replacement is no problem, so you do not need. Measure it again.

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...
