Beocenter 7700 default main power relay

6 replies
Hi, I'm gratefully owning a Beocenter 7700 with a Beogram CD 4500 and a pair of Beovox S2400. I had issues with it 15 years ago that could have been fortunately fixed with the help of this forum. But sadly the Beocenter doesn't work anymore. So here back I am. When plugged it's lighting weirdly and one of the 3 main supply relays is clicking uninteruptedly. I have checked the processor and it appears to be ok. I guess that I have to change the disfunctionning relay but it didn't find where to buy it. Any ideas the diagnosis and where to provide the parts? Thanks for your help.
Check the three large filter capacitors. Martin
Thanks Martin for your interest. I guess we are talking about the same parts that I called relays. An indeed, one is not functionning right apparently. But I don't know either how to check it properly, neither where to find parts to replace. Any clues still welcome G  
Martin is referring to capacitors, not relays which I believe are all 5000 mF and are C4, C17 and C18.    
Thanks Mark. I apologize for my lack of knowledge, I may be misnaming things so here a picture of what's disfunctionning. G
Hi, Did you find any solution for this problem? Best regards, JB
