Beolab 2 Powers on but no signal

I picked up a very beat up Beolab 2, it powers on when plugged in (red LED), but when I plug in the powerlink cable and try to play music, there’s no sound (still red LED, does not turn green).
I took it apart and looked at the fuse, it visually appears not blown. That’s pretty much all that I know how to do. Any common causes for said symptoms? Would the only thing that I can do be replace the board/sending it somewhere for repair? thanks!
Hi mojofml,
Do you have a multimeter and know how to handle that?
It is not a good idea to plug in power, having a red led and then connecting Powerlink. Can make a big PLOPP and then nothing in the future…
Has it ever worked before, did you see or hear it or bought defect?

I’m sure it worked before, before I bought it
If you don’t have/know how to handle a multimeter, try to find someone who does, and has understanding of power supplies and amplifiers.
Have you double checked your powerlink cable, or checked that whatever you have it plugged into is set up for it – or has working powerlink sockets?
I only ask as in 20+ years of dealing in B&O I have to say that the BeoLab 2 ranks as one of the most reliable and trouble free pieces of B&O I have ever dealt in…

Hi there, i’m absolutely sure there’s no issue from the signal/cable end, because I have another perfectly good working condition Beolab 2! I bought this as a gamble in hopes it would work (seller didn’t have cable to test the signal), but i guess not only is it very beat up on the outside it is also the case on the inside 🙁
Found the service manual, maybe it’s the base unit that’s faulty (the front facing piece)
Is there any way to test the base unit? I will not use my working condition Beolab 2 to test it 😀
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?

Yes quite noticeably something is impeding it when i press down on it, i’m trying to figure out how to take it apart. I can’t find a guide anywhere to do it, but i’m guessing I will need to unseat the spider to gain access to a few screws below it order to take it apart.
