Hello

My beomaster 6500 is suddenly having the following problems :

  • I can no longer activate the beomaster from link rooms
  • AV radio, cd etc no longer works (it is connected the a beovision with the 7/7 pin cable)
  • no more display on the pentas connected to the beomaster (this works when connected to the beovision)

Beomaster still plays sound (radio, cd etc) but the link functions arr gone. I suspect the datalink module or board is dead.

I think before this happend, there was a reported thunder & lightening while I was away from home.

Any help ou suggestions ?

Sim.

This probably sounds silly, but have you tried unplugging the system from mains for a couple of minutes? That was the solution when I had the same fault (no AV or link functionality, but I don't have any beolabs with display). Worth trying before you take it to the repair shop :-)

For the Penta display I think there is an audio/video switch. Did you switch it to audio when connecting the Pentas to the BM 6500 ?

For the other problems can you tell a bit more about your set up? Which Beovision - are BS 6500 and BV linked? Which linksystems?

Your remote(s)? Did you change anything in your set up? Maybe there is an option problem.....

Yes, quite common during a thunderstorm... some parts in the datalink section are dead. Nothing special, 50 cents on the pre amplifier board.

Replace:

D5= 12V zener diode 0.5W

TR1=BC547

That's all...

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 !

Any clues ? Welcome
