ModeratorSolder the old one out and solder a new one in.
Then do NVRAM reset as mentioned in the service manual.Martin

ModeratorThe service manual shows how to adjust the black excentric.

ModeratorFirst thing would be to replace the backup battery and reset the settings.

ModeratorI am not as active here as I have been, I must admit.
Down from about a dozen posts a day to a few per month.
Discussions are now spread all over the net, which is a shame, I think.I am not on Facebook. Never was and probably never will be.
I never visited Discord.
Every B&O enthusiast has his own forum now, it seems. Or Facebook page or Instagram or …or…or…
Having to visit hundreds of places to get information or help is frustrating and it is wasting time looking
everywhere instead of one place – and keeping track of where what happens, where did I ask the question etc. – oh no, it’s not for me.
Better to concentrate than to water out in my opinion.We don’t have many dicussions about products within my scope of interest here.
I don’t care for TVs, I don’t care for video products more or less as a whole. I don’t care for home automation
and I have very little interest in apps.
I know next to nothing about the newer products, and I don’t service them.
I don’t feel the need to make things complicated – just for the sake of doing that – when it can be done simple.
I actually wrote a longer piece about this a while ago, but decided not to post it, as it was more or less just my own
reflections and not really particularly helpful.Martin

ModeratorCheck the idle current settings.
Check for DC on speaker outputs.Martin

ModeratorSome versions have a fuse on the display board. Have you checked?

ModeratorYou would need an FM-module,
either FM 5A:
or FM 6:
Both are immensely rare.

ModeratorSpeed switching is done by lifting/lowering the idler wheel, running it on different diameters of the motor pulley.
The lidting is done by rotating a wire so that the “pin” carrying the wheel moves up and down inside a “tube”.
The mechanism could have seized up – take apart, clean and lubricate.Martin

ModeratorThese amplifiers blow with an “avalanche”, causing several components to burn and/or short.
It can be very tricky to find all bad components in one go – and if you miss one, it will start all over.
Seeing your board, I suggest you ask around for a complete amp module instead.
Perhaps not as challenging, but easily both faster and cheaper.Martin

ModeratorBeomaster 8000 has a huge rush-in current when powering up.
Your lamp will eat most of the voltage the Beomaster needs to start up properly, and the surge will trigger the standby for safety.
Use a variac instead.Martin

ModeratorPull the spring-loaded part only.
Not the whole round center assy.Martin
Dillen
ModeratorIf you are sure that everything else is fine, ask Danish Sound Parts for a good replacement motor.
It may not be immediately available online, but don’t let that stop you from asking.Martin
Dillen
ModeratorIs the belt running correctly on the barrel-shaped area of the motor pulley body? – Not on one of the pulleys flanges?
Martin
Dillen
ModeratorCould be a lot of things – and possibly a combination of power supply ripple, cracked solder joints, flaky connector pins and perhaps something more.
It’s safe to say that all Beomaster 8000s will need a complete overhaul by now, capacitors, trimmers, adjustments etc. if
not already done.
And they are worth it.Martin

ModeratorKeep it standard.
Tighten the contacts in the DIN sockets, and they will be fine.
2x 0,75mm2 cable is more than adequate – that’s also what the original cables are.Martin
Dillen
ModeratorThe parts in your photo look intact.
But perhaps that’s merely a photo you found somewhere?
Else – ask at Danish Sound Parts.
They are known to be able to help with many, else impossible, parts.Martin

ModeratorDillen
ModeratorI also add a dab of glue to hold the cables in their new position.
Else they will work their way back.Martin
