One side's speakers buzz ??

[michaela]

Hi, this seems like a great and very friendly site! I've searched the forums using various keywords and haven't found an answer to my questions, so I hope you will bear with me and my extremely, extremely limited grasp of tech. (It's possible another thread addressed my problem but that I didn't have the right vocab to know it!)

I have an entry level Kenwood receiver + 5 speaker (+subwoofer) set that is a few years old.

Everything was just fine until yesterday, when I finally figured out how to put up a wall mount. I now have the receiver on the wall mount, with the cable box on top of it.

Ever since, the center and left side speakers (front and also the rear surround) you can hear what you are supposed to hear, but on top of it there is a very loud and horrible buzz, medium pitch, not high like a dog whistle or anything.

the right side front speaker has no buzz at all, and the right side rear surround speaker has only very faint buzz.

I have tested the speaker wires (by interchanging them) and that's not the problem.

It's also not the speakers - I tried listening to the receiver directly through headphones, and again, no buzz on the right side, bad buzz on the left.

Any ideas? Please answer as if explaining to a five-year-old !! LOL

thank you very much in advance!

Electrical interference from your cable box could be the problem. Try moving the cable box away from the Kenwood. If that doesn't fix the problem, try plugging the Kenwood into a different plug in (power outlet). You can use an extension cord to accomplish this so you don't have to phyiscally move the Kenwood.

One of these things is likely to be the problem.

power supplys/wallwarts??

Do you have any of those little power supplys/wallwarts plugged in?( the little plug powersupplys for portable electronics such as Ipods, portable cd players, cell phone chargers etc..)
I ask because I had a simular problem when I had an iPod plugged in to my power strip. After trying many things, as soon as I unplugged the iPod the buzzing stopped.
Just something to try.

thanks so much for the ideas! Well, unfortunately, I tried both suggestions but no dice.

Forgot to mention - if it matters - when I listen to another channel (e.g., front audio aux input from my imac/itunes), the buzz is still there (and still only on one side) but it's much less than with the cable/tv/vcr...

I'm just baffled. Any other ideas?
