Please help as I am about return my Samsung set top box to Circuit City. I bought a new Samsung SIR-T451 HD Tuner hoping that I can use my OTA antena to receive HD programs for my new Panasonic 32" LCD HDTV. Following to the instruction, I connected the 3 video cables and the 2 audio cables from the HD Tuner to the connectors on Component 1 of the HDTV. I also connnected the antena cable to the ANT/CABLE Input on the Tuner. I could see and browse the Menu and the Help that came from the HD Tuner. However, when I tried prescanning the channels (allowing the Tuner to memorize channels), it complained of not getting signal. I know this couldn't be since I could receive regular programs if I were to connect the antena wire directly to my HDTV Ant Input.
Do you know what could went wrong with my set up? Is it possible to connect the Antena wire into my HDTV, and then output it to my Samsung, and re-input it to my HDTV?
