Any thoughts I can give him?
Looking for trouble shooting advice.
I have a Denon A/V receiver. It was on yesterday as I was watching football. At or very close to the time my wife plugged in the vacuum, my speakers started making a continuous popping noise. I unplugged the vacuum and shut down my system. Upon turning my system back on, it seemed fine until my wife ran the vacuum again at which time, I lost the left & right front and center speakers (i.e....they went silent). The back three (left, right and center) are all still working fine. The front three speakers (which are no longer working) are on the same wall as the outlet she was using for the vacuum.
Any thoughts? It seems very strange that the vacuum being plugged in nearby should have any affect on the speakers or receiver, but it is the one common denominator. The outlet she was using is directly below the three speakers.
