Chosen Solution
Hello, I recently bought a no backlight phone to fix but I’m having a hard time with it and I would really be grateful for some help. I will attach some pictures on the board from under the microscope so that might help you guys figure out what’s wrong. I have done some testing and I really am not sure what’s wrong with the phone. I have seen that someone else has taken off the FL024 and FL2044 filters and has replaced them with solder linking from one end to another pad. I have cleared that and have ordered new filters. I don’t know what the next step would be to this repair if that doesn’t solve the problem as the iPhone 6 is much easier because you just replace everything. The phone is completely dark and you have to put a light to it to see if very faintly.
Update (11/12/2017) These are the screw holes, is this long screw damage?
Do you have ZXW? You may want to check filters, Coil, Diode and Booster IC. Here is a video that gives a little explanation. But do not jumper the filters…never a good idea to take the circuits protection. https://www.youtube.com/watch?v=7QhqZjdk… UPDATE: Heres the pic you are asking for on the Backlight traces…
