Toshiba 34HFX84 and RF interference

Archived from groups: alt.tv.tech.hdtv (More info?)

This will sound odd to most here, but we don't have cable or
satellite. We watch DVDs and have rabbit ears for PBS (and sometimes
other off-air stuff).

We just replaced our badly failing 20" Toshiba with the 34HFX84.
Oddly, the rabbit ears won't work the the 34HFX84. We had very clear
signal with the 20", but on the new TV there's a lot of interference
and poor image quality.

It turns out the 34HFX84 is generating RF noise (empirically
diagnosed) of some type. I setup the old 20" TV with the rabbit ears
about twenty feet away from the 34HFX84. The 20" was receiving a very
clear, strong image. I turned on the 34HFX83 and then there was video
noise on the 20" screen. Not as bad as I had seen on the 34" when
using the rabbit ears, but still quite a bit of noise. Kind of like
what you see when you plug in a skill saw or other noisy motor and run
it next to a TV.

But, if I connected a VCR to the TV (via the F-connector antenna
connection) and set the 34HFX84 to channel 3 then the image was fine
watching a video. I'm not sure what that indicates. But it seems
like the 34" is interferring with the rabbit ears -- and at quite a
distance.

Looks like an excuse to order cable. But, I'm wondering if the
34HFX84 isn't generating an excessive amount of RF radiation. My
neighbors haven't complained (yet?), but they are all at least 100'
away.

Any idea if this is an uncommon problme? I understand using rabbit
ears is
embarrassing, but shouldn't I still be able to use them on the new
set?

I wonder if it is another Toshiba broadcasting international distress
signals. Don't be surprised if a search and rescue team shows up at your

I seem to recall one of their sets sending out a "SOS Message" a couple of
weeks ago that got national attention. It hit all the major news broadcasts.
Representatives of the Air Force, Coast Guard, and Local Law Enforcement and
from the FCC were involved in this particular case. Some where in Washington
or Oregon State. I presume Toshiba would be rather interested in your set
also radiating spurious signals that interfere with other receivers. FWIW
