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?

July 13, 2023 at 9:29 am #22121Hi 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.July 22, 2023 at 8:56 am #22321Have 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.
July 22, 2023 at 8:48 pm #22358I 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? - AuthorPosts
