I have done the following things witout any sucess :
- unplugged the whole system from the mains for a couple of time (> 30 minutes) and the plugge dit again
- disconected the main electricity borad to the house
My system is composed of beosystem 6500 connected to pentas. The pentas swith has always been set to audio.
Beomaster is connected to beovision MX7000 with aux link cable 7pins
Link rooms a conected to beomaster with mcl cable and each link room with MCL2AV box and connected to MX4000 ot beloabl 4500.
Everything (link and av) was working perfectly well since 20 years and till two days ago !
