Problem with FL2400/C2400 in iPhone SE
This is my first question right here. I’ve been looking for an answer to my problem but couldn't find it.
I have two Iphone SE (one is mine and the other is my cousins). My phone didn’t turn on after a screen changing. My cousins phone worked but the battery didn’t charge at all.
I could open them and see them under the microscope. Both of them had the FL2400 removed. I tried to solder them back but didn’t succeed and lost them.
So i shortened the pads of the FL2400 with a wire. Doing so, in my cousins phone i lost the C2400 cap.
So the result is this:
- My Phone: FL2400 pads shortened with a wire and C2400 soldered. My phone doesn’t turn on and Itunes doesn’t recognize it. But i measured the current and is around 100-200mA.
- My cousins phone: FL2400 pads shortened with a wire and C2400 not soldered. That phone doesn’t turn the screen on, but it is alive because Itunes recognize it.
So the question is, do i need to solder FL2400 and C2400 and may be the phones will work? or the problem could be elsewhere.
