[RFI] Unplugging TV and plugging it back in stops RFI problem (temporarily)

[Lloyd - N9LB]

Hello Mike,

I use the METAL CASE Tripp-Lite "Isobar Ultra" Diagnostic Surge Suppressor on my ham AC power and on my entertainment system AC power. It has a fair amount of filtering along with the surge suppression.  That took care of my entertainment system RFI.  YMMV

This has happened more than once.  I get on a 80 meter net and knock my wife's program off, I'm running about 600 watts.  I then try 50 watts and still kick the program off.  The next day all I do is unplug the TV for a half minute and plug it back in and I can run 800 watts.
Over the years I have added lots of toroids on many leads at the TV.  The power to the entertainment center is thru one of Jim's brute force filters. I guess I can try more toroids on the two HDMI cables going into the TV.
With the problem being intermittent, it looks like I can only throw toroids at it and hope one will work.  Any Ideas?
It seems to be happening more often, but the TV can work with no problems for months or a day.
