The best way to repair iPhone SE doesn't display

If your device has a frozen screen or doesn't respond when you touch it,Follows We received an iPhone SE today, customer mentioned it does not display after falling, but phone call can still be received from it, as shown in picture 3-5-1

The first step is to disassemble and test the device, immediate reaction we take is that screen diplay problem should be excluded.

Next step is starting to test the motherboard, when measuring the resistance of display pin J4200 by multimeter, we find the third pin is short-circuit, it diplays 5.7V as shown in picture 3-5-2


Test the circuit board to eliminate all the trouble, and eventually remove C4004 to get iPhone SE work, as shown in picture 3-5-3

The same fault we've already met on many devices, all of them are caused by C4004 , which can be defined as SE commom problem, as shown in picture 3-5-4

Slove iPhone X Won't Turn On

Customer delivered a iPhone X and described the fault is not to boot after the phone drop accidentally. It reports error 56 when restore the iPhone X. How to repair this fault? Because iPhone X is the two board connected through the middle column, it is easy to drop the point. It may be that the solder points from NFC chip to the CPU part have fell off. Take apart the iPhone X by iPhone Screwdriver Repair Tools , take the upper board off the main board, when separate the main board we see a row of points have fell off. Picture 19-3-1 Look at 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. Picture 19-3-2 Then the tin of the middle column is repaired by iPhone X BGA reballing stencil , and the AP part is welded bac

IPhone 6P Front Camera and Distance Sensor Fault

Image
Received a iPhone 6 Plus, the customer said that the front camera can not be used, and the distance sensor has problem too. The two failures are concentrated on the front camera flex cable, which is likely to be caused by the damage of the wiring. First, we have to eliminate the possibility of the external parts fault, then consider the motherboard problem. Remove the screen assembly and replace it with a good one, we still can't turn on the front camera and use the distance sensor. Disassemble to measure the ground resistance of the front camera seat of J1111 by Fluke digital multimeter , it is found that several pins are infinitely large, and the related inductors are loose when touch with the pen. It seems that the small components are pseudo welded. 19-1- 1 Remove the motherboard and observe it under the Trinocular Stereo Microscope , we can see that the touch was repaired before. 19-1-2 The back of the sub touch chip U2402 is the front camera seat J1111, an
