I am having a problem that I am not sure can be solved. The television that I have only has 1 coaxial in and 2 rca (red/white/yellow/) in with no outs. I have an older Kenwood receiver that I am trying to get it working with. Is this possible? How could I get sound from the cable (straight from the wall - no cable box) into the receiver? Is there any adaptor/converter that can help?
