Hey guys, I have a a pair of Beolab 4000 where one of the speakers plays only music (turns green) when the music is playing and I plug in the power cable. Then he pushes the music through and works perfect. The problem is that he doesn't turn green if he is connected to the power and then music is playing. Does someone know this problem and knows how to fix it? I have already done crosschecking with the working speaker, so we can exclude any problem with cables, channels or the amplifier (checked with another Ouverture). Is: Does not turn green by itself when music is playing only by repluging power Should: Turns on automatically to green when music is playing I would highly appreciate!   Best,   Manu
