This subject comes up frequently. A bullet through the middle of the screen
is the solution. Plasma TVs and screens radiate from the screen. There is no
fix for the problem except to destroy the TV. I had one ( 43 inch Zenith )
for 7 years and finally dumped it for a 50 inch LCD. Problem solved.
I had put toroids and chokes on every electrical wire on that Anti-Christ
with no success. Sure made working DX rough .

Subject: [TowerTalk] Plasma TV noise ideas?
I have read Tom W8JI and Jim K9YC "tutorials" on this issue.
I have confirmed that when the immediate neighbor turns off his Samsung
Plasma set the "noise" ceases. Today, I provided six 2 1/4 inch mix 31
toroids and several clamp-on's to my neighbor along with a simple
explanation (with pics) on installing them on the power cord close to
the set itself and again at the outlet end of the cord. An electrician
is scheduled to visit his home Monday. Samsung has asked him to get
confirmation that a good ground exists at the AC outlet serving the TV.
At that time, I will ask the electrician to install by-pass caps from
each side of the AC line to ground. If he has no clue, I will build or
most likely buy a filter. I do not, myself, want to alter anything in
my neighbors residence. "We" may also try to choke other leads involved
in his system.
In addition, the neighbor is continuing an effort with Samsung to have
the set replaced.
Any other ideas for remedies? The noise can reach S9 plus, peaks at 25
KHz intervals, but creates hash across the bands.
