Hello from a new member, but long time B&O owner and admirer.
Yesterday I was finally able to purchase a BM8000 with the hope of pairing it with my MS150.2s. There is a catch - the 8000 doesn't work.
When I viewed it, it was powered up and showing 9.9 for volume, 7 in the centre display, and 7 on the right display. There was no hope of further testing (no cables/speakers/etc), but made the purchase anyway.
Once home and plugged in, I was able to see what I believe to be the standby light, some relay clicking, as well as "manual" in the bottom right, which comes and goes based on the relevant switch. Turning a set of speakers on with the top switch gave me a gentle hiss which at least shows the amps are doing something. Shortly after, it lost the standby light, and the 4A fuse was found to be blown.
I have found circuit diagrams and have familiarised myself with disassembly. There are a few service stickers on the back, and the output boards appear to have had some replacement caps.
I didn't bother replacing the fuse as I at least want to replace the rather sad looking RIFA cap in the start up circuit (cracked, but not yet exploded).
Do the particular numbers it was displaying hint to the nature of the problem? I understand they have a test sequence.
Any hints would be much appreciated
