Antwoord op "iPhone 6 Plus front camera and screen problem (mainboard)"I've solved screen mysterious behavior - it turned out that FL2050 was loose and there was no connection with C2095. Probably I moved it while removing U2301. After resoldering FL2050 original screen works again. But I still didn't solve front camera problem. As you suggested, I've checked FL1166 - it's OK. I measured all beads again, they seem to be OK, they show 0ohm while phone is on. I put new U2301 and still front camera stays black. I've measured voltage on C2301 and it was ~3,5v on battery and ~3,9v on charger. It's too low, and I think it may cause the problem.
Antwoord op "iPhone 6 Plus front camera and screen problem (mainboard)"Minho, thank you for your answer, - I haven't checked FL1166, but I will do it tomorrow and let you know about the results. - I did measure these filters with battery disconnected, I'll check them again - I got ~3.5V with battery only, I'll measure it with charger plugged. - As I have wrote before, I've jumped the pins only for testing. I'm going to replace U2301 to be sure it's OK. What about the screen? Have you ever experienced something like that?
