Powerless phone unless orginal screen is on it.
I have been doing repairs for over 2 years now and every now and then I get a 6 plus in that will not work with any other screen. I put a new screen on it and the phone will not power on or anything. I try another screen and Same problem. I put the original screen on it and the phone works fine. All the screws are the same, the LCD's are tested and work just fine. I am leaning hard towards some type of software error but not for sure. Didn't know if anyone else has had this problem or an idea on how to resolve it.
Is this a good question?
