Trip & Henry,

Thank you for your responses.

Trip, this isn't related to my cell being in my pocket, but I'm aware of what you're describing as my BL4s that I have attached to my computer have a lot of static when a cell call comes in.

Henry, I only hear this low volume electric noise when the TV is on (i.e. not in Standby mode).  I find it reassuring that you're hearing something like this, too.

Trip, do you hear a similar noise when your TV is on, but without an input inputting?

Mark,

No, I haven't experienced this anomaly on any of mine. Is it static or a hum? And when you say that it's heard when it's not in standby, but nothing is playing, do you mean that you have a source muted or that you can simply hear it in the silent gaps in a television program.

For the record, the only two things I have ever known to make speakers hum (aside from the phone thing) are incorrect cables being used (which would not be the case with built ins) or the ballast on variable lighting on the same electrical circuit (which could absolutely apply). In fact, the latter occurs every few months and has become fairly routine (though sometimes a pain in the ass) to remedy. If there are any dimmers either on built in lighting or free standing lamps, the magnetic (or in some cases electrical) ballast may be bad. I even had to replace it in one of my showrooms once. 

I suppose you could run an extension cord to other rooms which may have different lighting scenarios to test this hypothesis, but I would also say that line conditioners are no match for bad or mismatched ballast on a shared circuit so don't rule this out just because you have one present.

Good luck! 

Dear Gang,

Anyone else with any insights to offer with regard to their BV8 having an electrical hum that's really only noticed when close to the TV.

I'm repeating the question as I'm about to send my BV8 in for servicing if this is something that no one else notices.  I've excluded all the things mentioned in this old thread by others.
