Cant plug my screen into my phone, it wont work.

Hi, I tried to change my phone screen because mine was cracked. I plugged in a screen from a different iPhone 6 plus. Everything worked. Then I tried going back to the old screen. Nothing popped up. I thought, this is weird. Then I tried to plug in the new screen. Nothing popped up. So I plug the cracked phone into my 2015 Macbook Pro, iTunes recognized it. So I plugged both the screens into the other iPhone 6 plus, everything worked fine. So I plug the screen back into the cracked iPhone, and again nothing popped up. The phone has a charge, and the vibration works. (To sum it up: Any screen I plug into the cracked iPhone wont work. When I put the Screens into a different iPhone they work.) Any suggestions on how to fix this? Thanks
