I finally got my Pioneer receiver from Refurbdepot.com after UPS, uh, misplaced it. I have everything hooked up and it all seems to be working od except for this loud buzz that comes through the system when either a commercial comes on or if a title is imposed on the screen such as the sub-titles used in "Law & Order". It also occurred in random instances when I played my DVD of Zardoz. I didn't notice it when I played a VHS tape. The monitor out on the receiver is plugged into my el cheapo tv via a video cable from the receiver to a RF converter that aoolws a connection to the screw-on antenna input on the tv. That is the only connection on that tv. Thank you in advance for your advice and suggesstons.
