    Would help to know what OS(PW8/8.1 or WM10 TP) are you running on it and also which phone it is.

    Software wise it can be many many things and is basically guesswork. You might want to backup as much data as possible and go for a hard reset.

    Hardware wise, it looks as it might just be a faulty sensor. There is one that blanks the screen when you are holding it close to the ear during a talk (at least on Lumias). If that is faulty, the screen may remain blank all the time, even though everything is working normally on it.
