No, the speakers in the linkrooms turn off, but the Pentas in the living room work as usual. The system cannot be started from the linkrooms, but I get five seconds of sound in the linkrooms, if I start the system from the living room. The MCL in the kitchen is one-eyed; that is, only the right lamp is lit, while the bedroom one is constantly lit on both sides.

I got brand new 10 m cables from Soundsheavenly for the new speakers.

Are you actually telling me to disconnect the linkroom by moving the Beolab 4500s to the living room? I should ad that I have the Pentas connecred not to the Beomaster, but to the Beovision 7. Also, the sound does not come on anywhere if I try to start the system from one of the link rooms; The MCLs click, but nothing happens.

I fixed the bedroom MCL, though, just by pressing the right hand side, and the lamp went out.

your questions:

1: yes

2: don’t know; how can I tell?

3: speaker 4-pin

4: it’s complicated; I have a converter that I got from Germany. It was tested and worked on another system. I had athread going a while back on that subject, but as things stand, I am not at all sure that it is working on my system. If I press any button on the remote in a link room, the box - not the eye - clicks, and then clicks again after three seconds, but the system is not turned on. If the system is already on and i press e.g. radio, I get three seconds of sound, before the linkbox clicks off.

gotta go. thank you for taling an interest in my problem!

6: No, I was looking at it from the back, or in a mirror, or something... the left one, of course!

You lost me there; the mcl system is connected to the BM7000 via the MCL & speakers on the back...

I disconnected the speaker powerlinks from the TV and plugged them back in the BM7000. Now I have control of the sound in all rooms, but no sound from the TV. So the problem was not, after all, in the MCL's, but in the setup of the TV and the BM.

Meanwhile, in my other, related thread, it was suggested that I download the Product Configuration Guide, which is not, unfortunately, compatible with my 64bit Windows. It iinstalls, but won't start, so I don't know what format it actually is.

Thanks for your support. The problem sorted itself, mysteriously, when I changed the cables for the loudspeakers in the kitchen; suddenly, the whole system worked, and I can now turn off, mute, or turn on sound in all three rooms, and the television works, too. Happy new year!
