Below is an example of why RFI is such a problem for consumers. This is a
response by Panasonic to my questions about TV RFI. Even TV manufacturer's
don't seem to understand the problem, or at least their customer service
folks don't have a clue at all. I'll probably get the same response from
JVC as well. Sony just e-mailed me their 800 number which has a VRU that
dead-ends me at a busy signal every time. Lot's of help that is! I won't
be buying Sony this time.
Remember this when a neighbor is complaining about RFI, and be willing to
help if they will allow you to. You're the only help he has out there!
BTW: I have alreay tried the suggested "cure" with my Sony picking up audio
rectification. An AC poewr line filter has no effect on that type of RFI.

> Dear Mr. Edwards,
> Thank you for your e-mail inquiry regarding Panasonic TV's. We recommend

> recommedations for the TV emitting noise to a nearby HF reciever
> unfortunately. If we can further assist you on any other Panasonic,
> Technics, or Quasar products; please contact the Panasonic Customer Call
> Center (1-800-211-7262). For your convenience, the call center is open
> 9:00 am to 9:00 pm (Est.; Mon - Fri) and from 9:00 am to 7:00 pm (Est.;
