Tutorial: iPhone SE Audio Repair

Receiving a iPhone SE mobile phone, according to the maintenance experience, if the audio part of iPhone SE has some problems, can not work properly, for example, the iPhone SE audio part has no voice at all, or there is no voice from the other side at call. How should we repair it gradually?

      

First of all, we need to check iPhone SE schematic diagram on WUXINJI Dongle, the iPhone SE audio part consists mainly of audio decoding U3500 and ringtone amplification U3700.

There are three microphone, one is on the iPhone tail plug flex cable, which is responsible for normal mode calls; One is on the small camera flex cable, which is responsible for speaker mode calls; The last one is on the boot flex cable, which is responsible for recording function when take videos.

The virtual welded or damaged audio decoding U3500 will cause calls without sound, leakage, large current or won't boot problems. So, if the iPhone SE no voice at all, then we can replace the new U3500 with Precision Titanium Alloy Tweezers.

The damaged ringtone amplification U3700 will cause iPhone SE no ringtone, no sound in the phone call, leakage, large current or won't boot problems. If the iPhone SE is no voice on the phone call, first we need to eliminate the problem of the microphone, and then use QUICK 861DW hot air rework station and tweezers to replace the U3500 and U3700.

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...

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...
