It could well be the power supply! I noise i've noticed on a few of my B&o machines (Beocenter 1, Beosound 1, ouverture, beolabs etc)

Very very soft from the beolabs have to have my ear very close to the speaker grilles, maybe just maybe it's the active speaker system in the TV. 

Hi,

I'm holding a BV8-32 and I feel sure the noice is coming from an internal fan which is cooling the panel.

Hope it help's

Helmut,

Thanks for taking the time to reply and for the insight.  Out of curiousity, does this fan noise that you're hearing sound like an electrical hum?  Also, do you hear it more when toward the top righthand corner of the TV?

TIA,

Mark 

I have a BV7 and I also hear an electrical hum, but this hum comes from the backlight of the screen. The humming is gone when the backlight is off or very bright.

I'm not sure if the BV8 has the "Picture Mute" function, but can you hear the hum when you mute the picture (P.MUTE) ?

Matt,

I believe we should distinguished between two noices - one is coming from the left, this is the fan and another is coming from the right. It sounds like a hum from a switched power supply - known as a hum from coils. It could be different in loudness and it is pretty "normal".

I don't care about it, because I hear nothing also when switching to "Mute".🙂

This hums comes from the backlight inverter and is caused by the thin metal blades of the inverter. It may need to be replaced.

Normally, these layers of metal blades are glued together with glue to suppress this hum. If you are a hacker you may try to fix it by yourself but only do at your own risk and if you know what you do. ;-)
