Ok I am new to the game and having problems with my R10 receiver. I can no longer watch any channel it just shows a black screen. I can hit info and see the header as well as the guide but when I try to watch a chanel... nothing. I called DTV and they did the usual reset confirm numbers thing and still nothing. It used to do this all the time and I would just re-set and get back to watching tv no probs. It says activate your DVR service (its active I check with DTV). Before I spend some money to replace this unit is there anything I can do? I am sure its some sort of software problem, my other box works fine.
