Infinite boot with black screen
Hi. iPhone6plus screen cracked and was left unused for months. I got new screen form ifixit, but after change phone does not “start". It power on and with a flashlight I can see a apple logo on the screen coming and going. So infinite loop with no backlight on the screen. Visual check says that cables and connectors are ok. Can a dead battery do this? Logic board?
Thank you.
