It's tough to test a TV set in the store, least of all RFI emisions from a particular TV, since they have so many on at the same time. You might consider having your local sales person write on the

Rick, I don't know your antenna layout there, but it sounds like you have some "RF-in-the-shack" problems. Assuming that your station grounding is adequate, try changing the length of feedline to you
