My iPhone screen is black

I accidentally dropped my phone on the floor and my screen went completely black. It will not come back on. But my phone is still on; It can still make all the normal sounds and things, I just can't see anything on the screen. I tried turning it off/turning it on, resetting it, and even restoring it. I don't know what else to do at this point. Does anyone know how I could possibly fix this or how much the apple store would charge me to get it fixed?

Press both the middle button and the power button AT THE SAME TIME and hold it and see if something happens. That usually works. Try it a couple times

Either a ribbon is disconnected or LCD internals are damaged… Do you see cracks on phone?
If you have accidental warranty, then go ahead with Apple store.otherwise don't bother. Should be an easy fix, check out some video tutorials and order some parts. If you're not comfortable, take it to a cellphone repair store
