In this article, we will continue sharing the cell phone repair experience for iPhone 8-X.<\/p>\n<\/p>\n

For iPhone 8 and 8 Plus<\/h2>\n<\/p>\n

1. The motherboard that marked with H3 K5, with a small current leakage is the common issue.<\/h3>\n

It’s caused by the PCB layer with problem, the only solution is swap the important chips like CPU, Baseband CPU, and EEPROM to a new board.<\/p>\n

\"Cell<\/p>\n<\/p>\n

2. For iPhone 8 Plus, the board marked with PC-V0 also with similar small current leakage issue.<\/h3>\n

The issue might be caused by the PCB design defect, can only be resolved by swapping PCB.<\/p>\n<\/p>\n

3. iPhone 8 and iPhone 8 Plus no charging and cannot be connected with computer issue<\/h3>\n

Normally, it’s caused by the charging IC with problem. Compare with the USB IC, iPhone 8 series charging IC with high failure rate.<\/p>\n

Can go to the charging IC directly for the charging or connection issue.<\/p>\n

\"iPhone<\/p>\n<\/p>\n<\/p>\n

4. The no service issue is normally caused by the transceiver IC with problem<\/h3>\n

We can reflow or replace the transceiver IC (U_WTR_E) with a new one.<\/p>\n

\"\u00c9metteur-r\u00e9cepteur\"<\/p>\n<\/p>\n

5. The Diversity Receiver<\/h3>\n

The poor soldering or pads missing of the two diversity receiver IC, can also cause no service or SIM card can not be recognized issue.<\/p>\n

\"Diveristy<\/p>\n<\/p>\n<\/p>\n

For iPhone X<\/h2>\n<\/p>\n

1. The middle layers between the logic and the signal board<\/h3>\n

Especially for the drop-damaged phone, the pads on the middle layer is easy to get lost. We can use the heating platform to resolder and bond back the two layers of the motherboard.<\/p>\n<\/p>\n

\"iPhone<\/p>\n<\/p>\n

2. The Face ID damage<\/h3>\n

For the Face ID repair logic and method, you can refer previous blog iPhone Face ID Not Working Repair Guidelines<\/a><\/em><\/p>\n<\/p>\n

3. iPhone X No Charging<\/h3>\n

The issue is normally caused by charging inductor L3340 and L3341 damage. If the inductors are damaged, better replace them with a new one.<\/p>\n

\"\"<\/p>\n<\/p>\n

4. iPhone X flikering screen and restart<\/h3>\n

Normally is caused by the inductor L2780 which on the power supply rail with problem.<\/p>\n

\"L2780<\/p>\n<\/p>\n

5. Speaker function OK, but earpiece function failure<\/h3>\n

Like this kind of issue is normally caused by Audio CODEC IC with problem, we can just replace it with a new directly.<\/p>\n
