Just to update in case anyone interested - I used a 9v battery and connected the base unit +/- terminals and hear a mild clicking sound. I've also managed to source a multimeter, i'm getting an ~8ohms reading so I believe it's working properly. Will try to test the board over the weekend as well.

I tried one other thing - i tried to put one of my beolab 6000 speakers through the "out" from the beolab 2, still no signal goes out to the speaker.

I've finally caved and took my working Beolab 2 apart, and tried putting in the base unit from the non-working Beolab 2 into the working one, and it still did not work. The light does turn green and I do hear a very weak hum if I turn it up a lot though.

I've done the 9v battery test, and as you can see in the video the difference is very significant. What I haven't though is to put my working Beolab 2 base unit into the non-working one to test the rest of the parts (ie. the board, amp, etc) from the non-working unit. I would like to ask, is there is any risk in putting my working base unit into the non-working Beolab 2? I don't want to end up with 2 non-working Beolab 2.

Also, any chance I restoring the non-working base unit? thanks a lot.

Hmmm, the left one is ok.

The right one is somehow "blocked", there is a hard stop in the membran. Maybe it was overload or somebody crashed into the loudspeaker.

Does it move by hand?
