Hi Guys,
Just as Roger says, plasma TVs seem to be eclipsed more & more on the
consumer market by other (RFI-friendly) technologies...
A friend of mine recently had his 5 year old big screen TV "expire" on him,
so he paid a visit to a local TV repair shop (rare though they are anymore
in this throw-away society we live in) to get the tekkie's opinion. Well,
the guy had a back room just FULL of big TV screens, lining the walls...
When my buddy asked if he could maybe buy one of them on-the-cheap & avoid
an otherwise expensive repair on his own set, the proprietor told him to
forget about it---all the TVs in that room were plasma types that had died
premature deaths themselves...
The guy went on to say that plasma TVs were a waste of money in that they
don't last long, they run HOT, & they're energy hogs. He also said that as
fast as the plamas come into his shop, they're replaced by LED / LCD
televisions.
In short, the days of plasma TVs are---mercifully---numbered. But I continue
to scratch my head in wonder as to how the federal regulatory bodies in both
Canada & the USA "type accepted" these abominable RFI-generators for
consumer use in the first place.
