iPhone 6 Not Turning On after Dropping into Water


Have you ever met the same accident on your iPhone 6? It's not turning on after dropped into water accidentally. It seems also a very common phenomenon. How to repair it? Of course, we need to diagnose the problem first before detailed repair on the water damaged iPhone 6 device. Let's read the article guide!



1. Tear down the iPhone 6 by cell phone opening tools, connect iPhone motherboard to DC power supply, and then press iPhone power button, the current stuck on 750MA.

2. Use UNI-T UT81C Scope Digital Multimeter to measure each circuit output for iPhone power IC, there is no any short circuits.

3. According to our experience, actually, for this problem, the best way is rosin method.

4. Apply some rosin on the iPhone 6 motherboard, and then use PPD 861D Plus hotair rework station to smoke the iPhone motherboard until it turns white. Supply power and boot it, after a while, do the same thing for several times. Then you will find the short circuit component is hot and discolored.

5. Check iPhone schematic diagram by WUXINJI dongle, we can know that it is C0616, and C0616 corresponds to a 1.8V, which supply power to the iPhoneNAND flash. So, short-circuit 1.8V causes iPhone 6 won't boot.

6. Remove capacitor C0616 with Precision Titanium Alloy Tweezers, supply power and boot it, now the current shows normal, and everything goes well.

7. Some capacitors are not in power, its resistance is normal, but in the case of power-adding, it's going to leak.

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...
