I have a URC2020 Universal remote that came with my new Shaw digital cable box. I have a new RCA LED TV model RLED2265A-B How can I get the universal remote to operate the TV as well as the digital box? I have tried all 3 set up methods in the remote manual. The TV says it uses the universal Sony code so I tried that as well. Nothing seems to work. I can watch TV but need to use TV remote for TV power and volumn and the digital box remote to change channels. The TV is HD capable but I don't ever plan to use watch it in HD mode. The TV hs a HDMI port amoung others but the digital box doesn't as it isn't an HD digital box. I can't see how that could effect the remote working or not. Can you please help?
