I pulled a 1988 Magnavox 47" PTV from alongside the dumpster at a thirft
store about a year ago. Although the set was old, it was in rather good
shape for the age and had never been serviced apparently from the condition
of the coolant. The coolant wasn't cloudy... it was filfthy! Like looking
into a petri dish with all sorts of things growing in it.

Not expecting the best picture even with new coolant since the set was so
old, I tore into the CRTs and refilled them with mineral oil after cleaning
so I could see how CRTs would do. There was quite a bit of burn in from the
normal raster, so everything took on a "warmer" yellowish tint, but still a
usable picture for a free set. I didn't bother ordering proper coolant and
left the set running with mineral oil since I was going to trash it
eventually

A year later the set is still running with mineral oil as coolant. No
leaks, no overheating, no clouding or bacterial growth yet. The CRTs are
very weak now, but it still runs!

This is no joke! You can use "standard" non-perfumed baby-oil.
Works 100% and is cheap.

I have a Barco Vision II video projector that is really fuzzy,
probably
due
to cloudy coolant.


Does anyone know where to get the stuff, and how much one needs for a
typical set of 3 CRT's?
