I have a problem with one of my Beolab 4. Since a view days it has some white noise / light bussing in the background. AND since the problem started the faulty Beolab 4 is a bit louder then the other one.
I already changed the Powerlink cable and the power cable with the correct working Beolab 4, but no chance.
Any ideas what is causing the problem?
I guess the problem is caused by the power amp.
Does anybody have a circuit diagram of the beolab 4?
What electronic part could be damaged?
