Screen doesn't work after replacing screen

I just replaced the screen on iPhone 7 and when I put everything back together the screen won't even light up... I don't know if it's the phone or the new screen... it was fairly simple to make the connections and I double checked them again and they seem to be seated properly... any thoughts or answers?

Answered! View the answer I have this problem too

Is this a good question?

Did you unplug battery before doing the repair?

Sounds like either faulty screen or backlight filter blown.

If you don't see display at all then it's probably faulty screen.

If just very dim display then backlight filter is most likely blown and you would need to bring it to someone that does microsoldering for it to get repaired.

Thanks- Definitely not the backlight filter since absolutely nothing shows on display... I double checked connections and still no display so hopefully it's a bad screen and not a bad phone...

Most common fault---bad screen. Second most common--long screw damage from overtightening or mixing up the screws.

So if I would have the wrong screw in the wrong spot will that damage the phone or will it correct itself after removing the screw? I removed all the ribbon bracket screws and tried the screen but it still doesn't work... I'm hoping it's just a bad screen... but really have no way to tell.
