Hello Martin,

Thank you for pointing me in the right direction. I haven't replaced the component yet, but will inform you when done.

Check C55 and D24.

Martin 

I measured both C55 and D24, both are correct, when desoldered.

Next I measured for R92 and R93 about  35 Ohm, should be 56K and 82K

It seems the resistors are faulty?? Although it was the last suspect.

any suggestions?

Resistors won't fail that way.
How did you measure them?
And how did you measure C55 and D24?

Martin

Hello Martin,

I measured C55 and D24 by desoldering them.

C55--> 2,2uf

D24 --> OK

Resistors R92 and R93 in circuit. They start at 33 ohm, but slowly rise during measuring time. There is no fixed value. I don't get it.

Difficult to take a guess at without actually having it on the bench.
The problem may be some place completely different.

I suppose this is where the electronic repairers 3½ year long education and decades of experience has to take over.
Where are you based?

Martin

Hello Martin,

I live in the Netherlands. What I want to try first is replacing both Diode and Capacitor. What I heard, the components can act different in a powered circuit. When I power it up , I get each measurement a different readout on my meter.

Hello Martin,

Today I left my Beomaster at a repair shop for B&O equipment.They checked, but aftermore than 1 hour, they couldn't find the cause. I left it behind for spares.

Wrong choice of repairer.
They don't know a thing about electronics.
