i have been given a jvc AV28R25EKS tv, and also 2 floor standing speakers. when i run through a test on the tv, it goes through each individual speaker, and sound comes out of each one. then when i put it back to normal tv, athough you can hear a faint hissing if you go right up next to the floor standing speakers, nothing comes out of them!! the sound is set to prologic 3d. the tv didnt come with a manual, puit i managed to find this one on the internet
