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.
