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.
