I can’t manage to connect my JVC home cinema to my Samsung tv. I am really new at this and don’t know any of the technical stuff. When I launch a DVD through the TV’s AV source it works fine but I can’t get any sound from the home cinema system when I watch normal TV. Can anyone help by explaining this simply? I have connectes the red and white RCA cables but it doesn’t work… what kind of cables do I need? Thanks a lot.
