[RFI] Samsung Computer Monitor an RFI Dog

I have a similar problem (to the Samsung TV) with a JVC flat screen TV. It 
will come on when I use a 160 sloper which runs close to the house at less 
than 50W.  Neither the touch buttons nor the remote will turn the TV off 
after its been turned on by 160 RFI, the only way to reset it is to remove 
the AC power cord for a couple minutes then it will work with either the 
touch buttons or remote.  Running 500W on 160 to a ground mounted vertical 
some 50 feet from the house has no effect on the JVC TV nor does the full 
legal limit to a tribander at 50 feet on a Rohn 45G mounted next to our two 
story house.

A few months ago, I inherited a nearly new Samsung display from a fellow
ham, who told me that the touch-buttons that control monitor went nuts
when he keyed his rig. He lives on a small lot and runs legal limit,
mine are mostly much farther from the shack, so I fired it up in my
shack.  It mostly worked OK, for the reasons noted, but not when I load
up a 160M vertical about 25 ft away with 1.5 kW -- the monitor does,
indeed, go nuts and eventually shuts down, probably due to a
microprocessor crash.
