Unresponsive display and home button after replacement

iPhone SE, iOS 12.0.1.

I just replaced the front display assembly and home button after I cracked the screen. Upon completion, I powered on the phone and immediately saw a light leak at the top-right corer, about where the rear camera is housed. After boot, I get the notification “Unable to activate Touch ID on this iPhone”

The display is unresponsive, and the home button doesn’t work. When I lightly touch the top-right area of the screen, the light leak gets worse. This made me think something is pushing up on the back of the display, but I opened it back up and I can’t find anything that I think looks out of the ordinary.

Any help is appreciated, thanks.

If you changed the home button the no touch ID message is absolutely normal, since home button is paired with the logic board. If it’s still working you’ll have to reinstall the original home button, or loose touch ID function, no way out. Check that the camera is sitting flush, if you didn’t touch the logic board that’s the only part that might be out of place and push on the screen, causing the unresponsive display.

I installed the original home button with the new display to retain TouchID. However, I still get that message, and the button functionality (even clicking) does not work. Still not sure why the entire display would no longer work.

There isn't much that can explain the issue besides some accidental damage during replacement. Check with a good light source and some magnification all the connectors are fine and clean from debris. If battery wasn't disconnected during replacement something might have been shorted.
