Phone display doesn't work even if the LEDs work

So for the first time in a long while i taken off my armored case for the Galaxy S5 Neo,wich became the worst decision as i reached for it when i got a call and it fell from my pocket.

The back cover fallen off as well as the battery,i pick it up and put everything in and try to turn it on.

I can feel vibrations and the top and bottom LEDs working but the screen will not turn on or anything like its not even connected.

I tried to take the battery out and turn it on in safe mode to the point i even slapped it on my hand like a TV remote in hopes that it will magically work but unfortnately nothing changed.

I'll soon will give it to my uncle that deals with this stuff but i was hoping that someone might have a solution in the meantime.

Thanks for even reading this and all!
