Hey maybe someone can help I just got this tv and I went to hook up my bose lifestlye to it and I get no sound. I never had a problem with my last samsung tv it worked fine. Is there a setting maybe for this tv. I use the red and white wires. I even put it in the cable box to make sure the bose works and I get sound if I do that but I need it in the tv so the ps3 will have it too.
