Note that (so I have read) some of the big-screen TVs are Part 15 Class 
A devices, not Class B; i.e., intended for use in a commercial 
environment, not for use in a residential environment.

ever-growing pot of cybersoup:

> I'm once again taking a look at the TV market.
> I'm particularly interested in a flat LCD/Plasma HDTV

> which has TVI problems when I operate 40/80 meters.
> I've been unable to eliminate it no matter what I

> all the inputs, proper grounding of the 
> surge-suppressor, moving my transmit antennas farther
> away, etc. but I have been unable to eliminate it.
> Another "cheap" TV in my house has never had a

> put out birdies on 20M until I added the toroids.
> My question is: how do I protect myself when buying

> I could take a portable rig and check as much as
