No sound to my home-cinema
I've pluged my 47PFL7606 to my "analogic" home cinema.
From TV i've used the optical connector and an digital/analogic converter box, then the R/L rca connector input to the Home Cinema.
When i try on the TV to select output sound "amplifier" the TV say "failure! speakers of the TV are active" and no sound get to the home cinema.
I've already notice this problem with TV programs, on an channel is good and another NO !
I don't understand what's append.
Thanks a lot to help me.
