Beomaster 5500 audio problem when turning on

10 replies

Hi I'm a new user, I'm not sure I'm in the right section, I have a problem with my beomaster 5500, to make the audio work I have to turn it on and off several times because either you don't hear anything or you only hear a speaker or you it hears softly, then sometimes I press reset on the master control and it feels good. This putting the speakers on output two because on the first, in addition to the problems indicated above, sometimes I shoot the audio to the maximum and risk of starting the speakers. Then when it is in use it works fine until it is turned off. I ask for helpoooo. Many thanks to those who will help me.

Replace the speaker relay.
I can supply the correct part (soldering required).

Ok thanks I'll change it and let you know if it works.

Yes, if you know the correct part.

But the socket 1 of the speakers is not activated by the relay, am I wrong?

Socket 1 is via the relay (allowing muting in the main room), whereas socket 2 should not be affected by the relay.

In fact the problem is on the second din socket.
Today I disassembled the relay I cleaned and reassembled it, the problem remained. Then I disassembled the relay the one next to the transformer was dirty with white powder I cleaned and reassembled it and everything works, this was the problem. Lost that the problem will return because the relay contacts are worn out. 

si sente morbido e solo con toni alti quindi la modifica del volume funziona. Nel forum ho letto gli stessi post ma nessuno ha risolto il problema. AIUTO » Ho cambiato i due relè ma il problema all'accensione è rimasto
