If you turn off the mains it will still conduct on the neutral.
A good quality surge protector at the TV might be the most
cost effective help. If you know enough electricity to wire up
a filter try to get a 3 phase one designed for switch-mode power supplies,
and filter the ground too.
Check for any big loops like through plumbing.
You can try find a 100Amp x3 phase filter for your house.
You need to locate it away from you and not too close to
the transformer or other ground rod. It needs a dedicated
ground that includes a buried piece of copper or aluminum
flashing at least 6' long and a few inches wide. Outputs
should be RF shielded. Don't believe the filter specs because they assume
50ohm sources (some publish the European specs that include low impedance
sources). You want the biggest heaviest filters you can get. In the 50 to
500 lbs range that means. Make sure you know what
you are doing or have an electrician involved.
No point in doing it unless you've cleaned up the sources in your house.

PUK replis - Thanks Bill - As you probably know the emissions are coming
from a 42inch Pioneer Plasma TV across the road so everything in a 50m
radius is contaminated. I have tried to speak with the couple concerned
having sent them a letter last autumn but they instantly discriminated
against me and have tried to criminalise me for speaking with them, if I could
get the model NO of the TV I could work on the manufacturers cos this TV is
the mother of all RF producers. A site called HAMNET on the internet
describes some of the problems that these TVs cause for amateur radio Hams. I
will look into the filter issue but I need a uk supplier any ideas. Everyday
I leave my home for many hours to get away from the emissions coursing
through the house and gardens, but intrestingy my wife especially seems oddly
tired when she spends time in the house she often sits on the sofa and
behind her is a vertical buried wire which when tested with the AM radio sings
loud and proud with the modulated signal from the Plasma, I say to her and
my children not to sit there and feel so stupid in doing so as there is
obviously nothing to see. From this we can see how difficult it is to educate
the public and evan our loved ones agaist this invisible treat.
