My phone was smacked out of my hand and it hit the top where the camera and stuff is and cracked though my screen protected i didn’t have a very good case on the case easily fell off where the camera and stuff is there is no glass because it all feel off when if first happened it lit up a little bit but now it wont light up at all. and its been like a week or two.
It sounds like that along with the glass and digitizer, the LCD was completely busted. This can result in a totally black screen. I would try a new screen to see, if that fixes your issue first. If not, there could be a lot of other things wrong starting with the battery and all the way down to a board level issue.
