Hello. Everybody left me hangin, I do something wrong.
Not yet!
You still have not given the full information I requested. These are not powered speakers. The amps are in the receiver. Which power cord did you pull? If you pulled the receiver power cord then there can be no sound from any speaker.
Now leave the power cords in. You need to disconnect all units except speakers from your receiver. With the receiver on see if the speaker still has the objectionable noise with all inputs diconnected. It the noise is present, either your receiver is defective or it is picking up a source of RF interference somehow.
If the noise is absent, reconnect your peripherals to the receiver one by one, and note if the noise appears. First the DVD player, then the TV, then the HD DVR. If it is the HD DVR that is responsible, then remove the cable in from the cable company from the unit, and retest. If a unit makes the noise unplug it from the receiver. Removing the power plug will not help. I mean the audio connections. .
Now this noise is only on one channel, so there is a possibility of you having a bad audio cable. Use a new cable to connect back to the receiver any unit that brings back the buzz when reconnected.
Let us know the results of all this and we will take it from there.
