I recently upgraded to Hopper 3 with one Joey in master bed. I wanted to retain the capability of a second TV in master bath which was previously connected via coax splitter with older DISH receiver. Installation tech said I’ll I needed to do was connect Joey in the back of unit with RCA composite cable to second master bath TV. I purchased the usual Red/White and Yellow RCA cable but cannot get color. I have switched around the RCA cable in every configuration possible. Even jumped over to the Five connection RCA cable in back of TV. Get audio and video but not in color?
