While looking into answers on ifixit i found this video : https://youtu.be/m8bLkwm9hJc in this post : iPhone 6 - irregular backlight flickering It shows the same problem i am having with a few differences.

  1. it happens all the time, no 50/50 chance of it happening like the guy in the other post said.
  2. it does not happen with the original cracked screen, with it all is working fine. i have changed the battery and have tried with 5 different screens, all have the same problem, some flicker more than others though. what is strange to me is that whenever i change back to the original screen there is no problems. anyone know what is up with this ?

I’m not sure why it’s not happening with the original screen and it’s happening with the other new screens, but it does sound like a backlight coil or a backlight diode or the backlight IC is going out, does it make a difference if you go into settings and turn the brightness of your screen up?
