I have 2 x BeoSound 5 and 2 x BeoMaster 5. I have tried connecting them both via a power link cable (see attachments). Nothing else is connected. On both of the BeoSound 5s the red standby lights are illuminated but the screen will not turn on when I spin the wheel, press "GO" or push the standby button. Is there something else which needs to be connected before the screen on the BeoSound 5s can be activated?
