buzz/hum from tv

I have a 31" Panasonic tubed tv in a HT set up. I am using the Paradigm Studio 100's/450cc/dipolars for speakers. Ensemble wires rca's/power. Integra Research RDA7 amp and Marantz av9000 preamp. I have a minor noise, when the tv is off, with system on, but the noise is about 3x as loud when the tv is on.
I have also noticed that the closer the speakers are to the tv (front/center), even with the sound system off, (tv on) the speakers pick up a buzz. There is also a buzz from the tv's own speakers (which I do not use).
I believe it's the tube of the tv. Does anyone have any suggestions?

Try grounding the outside of the cable connector to one of the screws on your electrical box or center screw on an outlet. I had the same problem and that fixed it.

Isolate the problem. Do you have cable? Thats always a big problem. Dissconnect the cable. What kind of lights? Any dimmer swithes? Do you have a power strip hooked up on an outlet with everything plugged into it?

Start with just the amp. and speakers. Then connect one component at a time. Keep us posted!

How close is stereo to the TV? Is it sitting right on top of the amp or pre amp? Does it need some room?

I sevice card access systems and was called out for a dead reader. Everything checked fine,except for the 17inch monitor on the other side of the wall backed up against the reader. I moved the monitor over about five inches and the reader started working. Big emf from them tubes.

I live near O'hara airport and some of the attenuators and or groundfault isolators actually cause interference with the jets. I could care less about cable. My HT sytem only uses my EAD dvd player.
