Guide: iPhone 6S No Display Repair


Received an iPhone 6S, it was not displayed after turning on. The iPhone 6S accidentally fell into the water, but the owner quickly took it out and it didn't seem to have been much damaged, but the iPhone 6S could still be turned on. How to repair the problem? Let's check in the article!


After receiving iPhone 6S, we need to test it first. Press the power button on the iPhone and the screen stays black. We try to call it using another iPhone. It works. The iPhone 6S responds, but the iPhone LCD screen is still not displayed.

Open the iPhone and connect it to the DC power supply to test the iPhone boot current, the current data tested is normal, which means the iPhone can be turned on smoothly. Now, we confirm the failure is that the iPhone doesn’t display.

Take out the iPhone motherboard, observe it under the Stereo Zoom Microscope, there are small trace of water on the iPhone motherboard. Carefully clean it up, and then continue to observe.

Observing the iPhone display socket and those inductance resistances around it, we found the FL4220 is virtual welding. We can open the WUXINJI Dongle to find the FL4220 place in the iPhone schematic diagram.


Now, use tweezers to remove the FL4220, and the use QUICK 861DW hot air rework station to short connect it.  Check if the surrounding inductor also has a virtual weld, if yes, we can short connect it by jump wire. After observation, there is no other inductors has a virtual weld.


Install iPhone and test it. Now the iPhone LCD screen is displayed normally. The repair is finished.

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...

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: Why iPhone X Voltage Keeps Jumping

After getting the iPhone X motherboard to test, we observe the current value repeatedly jumps between 0mA and 50mA on DC power supply , and it is different from the normal booting current. Next, test whether the power supply of every circuit is normal. PP_VDD_MAIN is measured 4.2V; PP_VDD_BOOST measured is 4.2V. PP1V8-ALWAYS is 1.8V, all the values are normal. But when testing PP1V1_S2, PP0V8_SOC_FIXED_S1, PP1V8_S2 and other circuit voltage that output by power chip U2700 voltage are jumping constantly. According to previous experience, voltage jump is usually caused by a power supply circuit of U2700 output. Measured with digital multimeter , there is no short circuit was found for the dipole value of all power supply to ground. We repaired iPhone 7P before and know that if crystal oscillator is false welding can also cause voltage jumping, And if iPhone CPU  power supply is abnormal also can cause voltage jumping. Check the crystal oscillator we find no problem, then check th...
