Hi there....

I have a nasty buzzing sound coming from my beolab 4000's when in standby. It disapears when switched on and comes back when off. They are in a link room setup. I was wondering if anyone else has experienced this or knows how to cure it?

 Many thanks,

 Sprkt.

Hi Sprocket,

                  have they always done this or is it a recent problem?

Hi Chris,

It is quite a recent thing. It happened a few weeks ago and then stopped without explaination. It has now started again today.

I just cannot understand why its only happening in standby!!

 

Kind regards,

sprkt

Does the buzzing sound like a relay going off and on ?

What are the Beolab 4000's powerlink cables connected too ?

If so this is almost certainly going to be an earthing problem.

Also if the buzzing does sound like a relay, has any new electrical/electronic equipment being added recently which runs off the same power ring main ?
