My mom just bought a new surrond sound set up for her house. Its a Panasonic SC-HT733 in case you were wondering. I was trying to set it up for her, but there is a very annoying buzzing sound coming out of the left and right front speakers. I can't figure out how to fix it. Any ideas?

Shake out the bees.

It sounds like something might be grounded or not grounded where it shouldn't.

What source are you listening to when you hear the buzzing? I remember one time I had heard buzzing when I fed the audio out from the TV to the AUX in on my old stereo. I needed to turn down the volume on the TV which was causing the buzz and use the volume on the stereo.

I thought that I just needed to turn down the tv volume, but that didn't work,

Make sure the speaker wires aren't touching each other. One single, tiny strand of metal can cause serious problems to your receiver. Also check to make sure the pairs of wire for each speaker are in the correct output.

Is everything plugged into the same outlet?

Are the connections properly connected? Video Out on the Panny to In on the TV. No audio connections wired to a video connection, that sort of thing.

It is also possible you are trying to send the wrong signal to the wrong input.

I would check all the suggestions in this thread and then go slowly and connect one piece at a time and test it. Then continue.

No dice. Everything is plugged in right and all the wires are separated. Maybe its just a bum unit.

Sounds like Ground Loop. An isolator would probably eliminate it.

Hmm. Didn't sound like a ground loop to me. But you can check for that, too. Usually caused by a cable line that is not grounded properly since cable installers can't be bothered to do their job right.

At this point I'd probably try trading it in. Sometimes electronics are DOA.
