How do I fix a black screen?

[AC Question]

I recently dropped my Galaxy Mega and it didn't crack or anything but the screen went black. I tried the smack method and the 1 2 3 battery method but it didn't work. My buttons work fine; I tried turning it on and it vibrated and my blue led light lit up and my volume and home buttons work fine also it's just that the screen is just black. How do I fix this? All solutions are welcome. Thank you!
