One should never dump B&O.......plenty of people here will provide advice on preliminary checks you can make as a starter for 10

Replace capacitors on the power supplier regulator module.

Martin

many thanks Martin,

as usual, you hit the nail on its head  😁

a 4 cap change as suggested brought it back to life.

I left the two 5000uF ones untouched for now as I may change all electrolytic caps

at a later stage - so far it is working nicely !

the only other thing I changed were those wood-trim panel - they are now brushed Aluminium,

which looks much nicer.

cheers

just a brief impression of a wonderful sounding BM - with PSU recapped and balance-slider repaired - thanks Martin !

I wonder if my hearing is deserting me but this BM2200 amp sounds so unbelievably "analog" - way better than my BM1600, 1700 and even 7000 -

no excuses 🤒

can you spot the slight modification ??

cheers ALF

I did spot the difference, looks nice!

Hi Martin,

I'm having the same issue with mine have done this, caps on amp boards and the smoothing capacitors and I still have no sound. I was wondering if there is anything else it could be? When you power up you get a power up noise from the speakers.

Kind Regards,

Lewis

Did you replace the capacitors on the regulator board?
- And I am not referring to the two large cans held in the metal bracket, I mean the ones ON the underlying board.

Martin

Hi Martin,

Yeah I have done the ones on the board underneath and still it's doing nothing, is there anything else I can have a look at to see if that's  causing it.

Kind Regards,

Lewis

I seem to remember it has a muting system when switching sound source (to avoid pop sounds), perhaps this is where
the problem is. 
Connect a signal generator to the tape input and put a scope to the signal path to see where the signal gets lost.
