Why is My nokia Lumia 820 Screen Black?

[MullibMulessiua]

My Nokia lumia recently as been showing a black screen, first it started appearing some awkward pixels around the top right corner half moon i couldn't see well in that area then in the next day i woke up and there was a black screen on my cellphone screen literally i cant see nothing just a black screen i tried doing soft reset ( Volume down+ Power button) Didn't solve it, the windows home screen key, back, and search keys are on but the screen black, i continue receiving notifications can ear them well but the screen black.

Any help would be thankful.

Will i need to change the screen or something if yes how much does it cost? My lumia is pretty new it has like 2 months.
