Sometimes screen turns on, sometimes not

[intermodal]

Got in my Pinebook Pro a week ago and have been using it here and there.  I like it, but there's a problem.  Sometimes when I turn it on, so does the screen, but more often, the screen doesn't turn.  The light is orange for a few seconds then green, but no video output.  Anyone have insight on this one or do I have a faulty unit?  It's only warranted for 30 days so if there's a problem I'd like to get on it quickly.  If it's something I can handle by opening it up and doing something inside, I'm very comfortable with that sort of thing.
