Hello everyone, I’ve an iPhone 6 that turns off and turns on alone. I do not know why. I was already, restore the phone, change the battery and the screen because when the screen is off, a horizontal line (red, green, blue or white) appears, but the problem continue. I think the problem comes from the motherboard but, I prefer to be safe. Thanks if, you have any ideas.
It could be that the power button is stuck Update (01/06/2019) There is a little antenna style connector on the bottom of the board below the battery connector make sure that connector is on all the way I had a similar issue once
