Up until yesterday it worked fine this way.
Today as soon as I turned it on I heard a popping sound and it smoked. Practically the integrated display MM5450N is burned, I do not understand why.
Can it be replaced? could it burn again?

Beomaster 5000 power problem
6 replies
Hi, I have a beomaster 5000 with a blown fuse, I replaced the battery, all the capacitors on the power amplifier board and the preamplifier board. Now when I turn it on the two relays trip but the red light doesn't work, if I press the button it turns on then you see the word loudness which fades away. Can anyone help me? what could i check?
Can anyone help me?
Hi everyone, I've partially solved it, there's only one problem left.
When I plug it in it doesn't turn on but when I press a button on the control faceplate it turns on and then it works.
When I unplug it and put it back the problem reappears....????
Please does anyone know the problem? And do you know what I could check to fix the problem?
Thank you.
Have you double checked the connections to the processor board (one by one) at the front of the unit. If it is actually turning on (which is a good sign, didn’t fry the CPU ) it may be a connection issue seeing as the cables and corresponding plugs are pushing 40 years old. Additionally, you may want to look at the internal IR sensor. They can cause a host of unusual problems when they start to go bad.

B&O fan here since adolescence; on again off again Beoworld forum lurker since ‘07.
Current lineup of complete systems includes:
A painstakingly restored Beolab/System 8000 (Late model Beomaster 8000 driving M150’s, Beogram 8002, Beocord 9000, operated via Beolab Terminal, and housed in an SC80.1 cabinet. Beosystem 7000 (Beomaster 7000, Beogram 7000, Beocord 7000, Beogram CD 7000 connected through a Beomaster AV 7000 (for extra plug and play connections) driving Penta 2’s and Beolab 6000’s (via powerlink) through the AV7000 and a Beo Conna sub + CX 100’s on the Beomaster 7000’s internal amp. Beosystem 4400 (Beomaster 4400, Beocord 5000 (original model, 2 head revision), and Beogram 4004) driving MC120.2’s
Finally, a Beosystem 5000 including Beomaster 5000 driving S80.2’s, CD50 (with
separate, Terminal 50 remote) and both Beogram 5000 and Beogram 5005 record decks.
Current singular pieces include: Beomaster 1600 (tractor belt version) S45-2’s, (refurbished) RL 140’s, Beocenter 7700 with matching SC70 cabinet and a few too many whole and parted Beomasters, Beocords and Beograms to list.
Kind of an embarrassment of riches (or a hoarding problem in the making as my family puts it), but life’s short. More than happy to share or lend a hand if anyone needs anything.
I have another one that works and I tried to replace the processor board but the problem remained, then I also changed the display capacitors but the problem remained.
The relay works but maybe I should replace it anyway just to be safe?
