I unplugged one of my boxes this morning while doing some work in my equipment closet.  After I plugged back in, the box no longer turns on.  I can see it rebooting (four orange bars), but nothing else.  When I put my projector on the input to show Voom I can see a screen that says Voom, but on the box there is nothing (no red or green satellite symbol).  Anything I can do to get this to work?  No problems before I unplugged.
