We gained an iPhone 6 want to be repaired, the issue is that the iPhone 6 has no display when it’s became on.
First test whether or not the iPhone display socket has water broken or digital welding downside, after taking out those issues, measure the resistance worth of the socket by way of virtual multimeter.
After size, we discovered the display socket 12 pin does not have resistance worth. Check if the attached c2001 capacitance and fl2034 inductance have corrosion and digital solder issues, the fl2034 inductance measured are not any resistance worth.
The fl2034 inductance passes during the U2403 6 pin tube after which to the CPU. Using a virtual multimeter to measure the iPhone contact display screen regulate IC U2403 of the corresponding backside pins, the knowledge examined are customary. So, we will be able to do away with the CPU downside. In this situation, we want to solder bounce twine.
Use QUICK 861DW sizzling air remodel station to take away the duvet, after which solder a jumper twine from the sixth pin of u2403 to a measuring level subsequent to the screw hollow，after which solidify it with inexperienced UV oil.
Install the iPhone and take a look at it, the failure has been solved.
