Satellite X1 Boxes not Working

I just did a self-install upgrade to X1. XFi and the main DVR box is working fine, but the small satellite will not play TV shows. I can see the guide, but when a show is selected only a black screen with no sound is displayed. Shows recorded from the main DVR play fine. The system will occasionally display a message that it needs to restart all the TV boxes. When I restart all, the system comes back with the same symptoms. Can anyone offer any assistance?
