Solution: iPhone 6S Not Charging


We are going to repair a iPhone 6s with charging failure, it's a common problem for cell phone repair technicians, how to repair the problem step by step? Let's check in this article.

The iPhone 6S motherboard has a slight water problem, resulting in the iPhone 6S can not start, after repair, the iPhone 6S can be turned on normally. However, after testing, the iPhone 6S won't charge, and when plugged into the charger there is no response, no sign of charging, the iPhone can connect to the computer.

Use Stereo Zoom Microscope to observe the iPhone charge circuit, there are no visible signs of water damage on iPhone tail plugs.


Considering that there is water damage on the motherboard of the iPhone and that the iPhone can be connected to a computer, it is important to study the water damage circuit on the motherboard of the iPhone based on previous repair experience. After careful examination, we found that the resistor R45 10 was corroded by water.

After checking iPhone 6S schematic diagram on WUXINJI Dongle, we know that this circuit for iPhone main power that output to the USB control signal TRistat_USB.


Now, we found the faulty part, so, clean the corroded area and replace the resistor by using QUICK861DW hot air rework station and Titanium Alloy Tweezers.

Install the iPhone to test, all functions works normally.

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...
