I have a dual tuner DVR receiver. HD on output 1 only. Left for work yesterday and everything was fine. Came home and TV 2 says it does not recognize signal. TV1 works fine. On phone with dish for 1 1/2 hrs last night, and no fix. It acts as if it is on the wrong channel but it is not. I have tried channel 60, and 73, I have unplugged the tv, reset the receiver, and have done a channel search on the tv (which found no channels). I won't be available to take off work for someone to come out until mid next week. Is there anything else I can try? Thanks
