OT: TV RFI Question

We’ve got three plasma TVs in our home. One is a 9 year old Sony that is small (by today’s standards) and causes zero RFI on my K3. Another is a piece of $&$% Samsung that completely rips up 160, 80, and 40 meters. The third (our main TV) is a Panasonic Viera that up until tonight has not caused any RFI. But I guess the honeymoon is over, as 40 meters tonight was unusable while the XYL was watching one of her shows.

So, if I can convince her to replace the Panasonic I’m wondering if folks here have had any RFI issues with the new OLED TVs? We’ve enjoyed the quality of the plasma TV’s but enough is enough.

Hi Jim,

I've never heard any RFI from my 60 inch LG OLED TV.

Jim,

Ditch the Plasmas and be sure they leave
your neighborhood.

I've got one of those insanely oversize LG
OLED TVs and it puts out zero RFI that I
can see on the P3. I did a lot of testing
during the free return period just to be
sure I wasn't bringing a noise generator
into the house, and it's excellent in all
ways. Also, it uses so little power
compared to a much smaller Vizio TV, The
glass is cool to the touch and the
processor compartment is slightly warm at
most.

OLED can produce a lot of brightness and
power consumption relates to brightness so
how you set it up matters energy-wise, but
your Plasmas are multiples of the power
the OLED uses. One very nice thing with
OLED is you see genuine black, no backlit
shade of gray, it takes awhile to get used
to seeing very accurate color and shading
when watching in a darkened room, we don't
see that with the other kinds of TV.

I'll second that. I had to buy a neighbor a new TV just to get the
plasma one out of the neighborhood.

Plasma TV sets are often big RFI generators. And, they have the annoying habit of developing burn-in... much like CRTs if a constant image is displayed. I used to work for a TV network that used plasma displays as part of studio set decorations, and they quickly discovered that using a plasma display for an identifying graphic (a logo or some such) resulted in major burn-in, in part because they pushed the brightness of the display, so that it could be picked up by studio cameras in a brightly lit set.

RFI was not a big concern at the TV studio, but there have been many stories of neighbors who purchased a plasma TV set that happened to ruin their radio reception... as well as the HF activity of nearby amateurs.

Do they even still sell Plasma TV's?

I sprung for a regular LED illuminated, LCD screen LG 47 inch with 3D, which turned out to be a total bomb, about 5 years ago and have never heard a peep of RFI from it.

I DO watch "John * Carter" in 3D every so often, but it's the ONLY movie I have in 3D.
(The LG method is the same as used in movie theaters, with totally passive 3D glasses.)
