Look at the screws in the little plate that goes on top of the lcd connectors. The bottom two and the middle one should all be the same length, the top left being a little longer, and the top right longer still. If there are longer screws in shorter holes (a longer screw in one of those bottom 3) you have possibly damaged your board. Google long screw damage, its most known on the iphone 5s rather than the 6 but is still an issue, it just presents like you're describing as opposed to BSOD

The repair is to rebuild traces along where the board is crushed, a repair for the highest level of patience and skill, far beyond my skill. There is a sendoff/mail in service that can be found online based out of new york that can possibly repair it, otherwise you're kind of stuck for a trip to the apple store and a $323 out of warranty replacement IF this is the damage on the phone.

I did check but there's nothing working with the connectors or anything could it have been the crazy glue I used I checked the lcd connectors on the board and they all seem perfectly fine

unless you made a giant crazy glue mess on the board instead of just keeping the glue on the display, I'd think that isn't what caused it.

Do you have a microscope? Look down in those 3 nuts specifically the one on the left side and see if you see any copper.

It sounds like you've lost the backlight for whatever reason, long screw damage would do that, theres other board components that can be damaged but typically not by just a display replacement.
