Problem with FL2400/C2400 in iPhone SE

Hi everybody,

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.

Thanks!

Fl2400 will need to be in place the cap doesn’t really matter, did both phones have the battery disconnected when you connected the lcds

Yes both of them had the battery disconnected. I also checked the backlight filters of the display circuit and are OK.

So i should try replacing the filter then.

I have to see where to buy them because in my country (Argentina) i won’t find them.

Thanks a lot!

Is that possible that not having the FL2400 can impact on no display at all?

No it would usually only cause a battery percentage issue.

Do you think of any other test that i can do to troubleshoot this?

Can you buy zxw. It will give you diode readings for the lcd connector.
