I have a Sharp 27" TV that is 7 years old. It has two sets of RCA input points but no RCA output. Currently, it is connected to the cable with the standard cable (I think it is called coaxial..I am not sure though). I have a 6 speaker system that my DVD is connected to. It has multiple input options including DVD, AUX, GAME etc. I want to connect my TV to that speaker system. Is there a cable that will take the standard TV cable and convert into RCA at the other end? I assume I cannot use the RCA input points on the TV to get sound to the speakers.
