@goosefootba since it dials out etc. but just does not display anything after a drop, as well as "some little flicker" is a pretty good indication that this is a failed screen.
I suggest that you replace the display. Since iFixit does not yet have a guide for that use something like [https://www.youtube.com/watch?v=YpsHOUO6kc4|this video] Replacement displays are readily available at many online stores.
While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
