It's the humming from the power supply I think this is normal

I've never had any buzzing noise from the in-built speakers or from behind a panel from any of the Beovisions I have had. I'd say this is not normal at all. You shouldn't be able to hear anything, especially from a new Beovision Avant. This seems to be coming up more and more and now seems to be a recognized fault or issue with build quality. Get your dealer to sort it out.

Well, typically, as soon as raised concern with dealer, the noise is back to normal levels (i.e. very quiet and can only be heard if you stick your head behind the TV right up to the panel - and is still not particularly noticeable).

Will ask dealer to log it if it reoccurs, at least I know what I was hearing before was not within normal parameters as has rectified itself for now.

Fingers x'd.....

I am having the exact same problem with my Avant. The noise comes from the upper back of the tv (when the screen is on) as you describe and is noticeable within a distance of up to 8-10 m, if the sound of the tv is muted. Of course you have to listen carefully, but the noise is there. Is this acceptable? Did you get the problem fixed?

My Beolit 15 doesn't make any sound when not in use (power on) and I have a very good ear for that !

Every BeoLit 12 and 15 I've heard make produce a slight buzzing background noise. It's easy to hear for me. But perhaps your unit is better. I've not listened to many BeoLit 15's yet.
