[RFI] 20 Meter Noise Level

[K1TTT]

Well, you pretty much proved it is the tv... unless maybe you have it on a
ups that gets noisy when it is loaded down.

The easiest thing to fix is if it is from the line cord, add some ferrites
or a line filter to see if that helps.  If it is radiating straight from the
case then you can try wrapping it in aluminum foil like my tv is.
