It's well known that many plasma sets generate bad RFI, but the 
advice I gave generically applies to any TV. That is, you can choke 
the wiring and kill the external antennas, but if the set has bad 
shielding, it's likely to be a major engineering project to fix it. 
The best advice for that sort of thing is to dump the product to 
someone who won't use it close to another ham, and buy a good one.
