Has anyone had issues with activating an X1 companion cable box? I have (3) X1 boxes: 1 main DVR and 2 companions. I have 1 companion box that I haven't been able to get working. I've tried all the basic troubleshooting with the jokers at Comcast tech support (tier 1). All the basics are covered: no coax issues, HDMI issues. The other boxes work on the outlet so I know I have adequate signal. I've also replaced the box in question with a new box and the new box is duplicating the same issue. When I power on the box I get "XFINITY" in red letters on the TV for about 3 seconds. It goes to either a black or gray screen. The lights on the box (model RNG 150N) light up in sequence from: Remote to Data to Record. The box is unresponsive and I have to unplug it. If I power it back up the same cycle continues. I've spent 8 hours on the phone with tech support...nuff said. Any insight?
