[Elecraft] K3 & Plasma Question

This is only slightly off-topic, but since I do operate a K3, it still fits - kinda!

We have two plasma TV's in our home. One is a ten year old Sony 42 inch unit. The other one is a two year old Samsung 63 inch TV. They are about 50 feet from the shack, and only eight feet away from each other - two different rooms. The Sony has never, ever caused any sort of QRN on any of the ham bands. Because of that, we purchased the Samsung unit right after moving into this QTH. I did not have an HF antenna installed for several months after moving in - when I finally did get one put up, I saw some ugly QRN on most of the HF bands. However, at the time I was not aware of the "plasma effect" that I am now. When I heard the QRN, I "assumed" it to be from the PG&E high power lines that are pretty close to the house. By the time I put two & two together and figured out that the ugly noise was from this Samsung TV, it was already out of warranty. Ughhh….

We are now in the market for another TV, and have been looking at a very nice Panasonic 65" Plasma set, model TC-P65VT50. I've already told the Best Buy sales manager that IF we do buy it and IF it causes QRN to the HF bands, it is coming right back. He said that is no problem. But, if I can query this group to see if anyone else has one of these TV's, I may be able to avert a lot of work ahead of time. Our second choice would be an LED set, but after seeing plasma and LED side by side, playing the exact same content, I want to stay with plasma - BUT ONLY IF IT DOESN"T SCREW UP THE K3!!!

So, is there anyone in this group who has a Panasonic TC-P65VT50 TV who can say yes or no to the QRN issue?

Thanks, Jim / W6JHB
