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?

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...

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 :D
