    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.
