Final ColorTrak2000 model...

I've had a 31" ColorTrak 2000 since it was new
in 1990. It had a failure in the potentiometer
for the green drive while still under warranty and
was repaired for free. The set was sold as a 'monitor',
so there is absolutely no compensation for signal
strength variability from different sources.
LaserDiscs always looked washed out compared to
over the air or cable signals, but then DVDs came
along and gave the set a whole new gamut of color
and dynamic range.
The set was built in Canada. It was already under
Thompson labeling, but I think was leftover from
previous ownership. It was the last year before
RCA came out with 'ProScan' as their flagship.
The set has excellent color-rendering capability
and will be great to run with the new HDTV signals,
when converter boxes become available.
It does have a problem that has baffled techies
over the years. In humid weather, it will shut down
and go into oscillation of startup and shutdown
without becoming useable again. Sounds like a
major defect, but I found the source of the problem after years of study on the interned and
my own non-technical observations. There is a
tall, rectangular white ceramic resistor in the
high voltage section which can be pushe with a
wooden dowel to re-set the TV to normal. It works
every time, though sometimes bearing repeating
2 or rarely 3 or 4 times to get weeks and weeks
of use once again. I keep the back cover loosely
attached so that I can open and poke when needed.
It's something about the circuit board, I know,and
it's something that would condemn most of these
sets to the ash heap of history. But the picture is
so clear and focused and wide-spectrum in color.
What a shame, eh?
Does anyone know the specs on the final ColorTrak2000?
I think it was the last year before Invar masks,
so it's not overly bright. It has lots of useless
digitial effects built into it and the large remote
control. A real curiosity!
