Why does my device have a black screen?

[AC Question]

My device is at a black screen

I was able to use this morning (pst), then at about 12p I was going to make a call and haven't been able to retrieve even my lock screen pic. Is there something I need to do? Others than try to turn off/on, which I get no response either.
