Device won't power on after screen replacement
Hi! I'm relatively new to smartphone repair, but been in IT for years. I've run into an odd issue with a screen replacement on an iPhone 6s.
With the original screen connected, (with no home button) the device powers on and responds to the vibration rocker switch.
I turn the device off, swap in an identical replacement screen from ifixit, (albeit white instead of black, also with no home button) and the device REFUSES to turn on.
Done this about 10 times with the same results, so I'm fairly certain I'm not shorting the phone out with the replacement screen. What could possibly be wrong?
