Relocated my 722k to the bedroom and am trying to connect TV 2 in another bedroom with an RF modulator but have had no luck with getting a picture. I have checked all connections and made sure all diplexers were placed correctly. I have gone back and forth to the modulator setup page and tried everything but still no luck. The TV in bedroom 2 is an old Memorex SD with standard coax input and RCA jacks. I have a dual LNB dish with one 611 in the living room and the 722k in the master bedroom. There are two feeds coming out of the dish and I suspect from reading on here that a switchbox is built into my dish. I'm using one diplexer coming off of the dish with the sat feed going into the master bedroom and the UHF feed going into the second bedroom. Also on the 722k I am using another diplexer with the Sat 1 Sat 2 combiner going into both tuners with the UHF line feeding into the home distribution port. Can someone tell me what I'm missing here?
