Please help.
I thought that the green tube in my older Magnavox PTV had gone
completely. Then I notice that the tube still works, but only lights
when the image calls for maximum "greenness"- typically cartooons, a
pure bright green. Apparently, "green" grass/trees/etc. are not bright
green enough.
Can anyone give pointers to fix this problem? I've already done the
coolant change, and the tuner chip replacement. It's sort of a battle
between me and the engineers who designed the thing, just to keep it
working.

Thanks

It's a 95% chance that the coolant fluid in all three of your
projection units is contaminated, especially the green. Look straight
into the lens, if you don't see a sharp cloudless unfogged image, your
fluid needs to be replaced. DO NOT OPEN until you know what your up
against.
