You're right--the color killer logic is somehow inverted.
That will be an interesting problem to find.  ;-)

That's not a "trimpot"--it's a variable capacitor used for
adjusting the phase of the color burst, or "hue".

Usually, its setting is more stable than the hue setting of a
monitor, so before trying to set it, tune in a local newscast
or view a DVD on the monitor and adjust the monitor so that its
hue and saturation are proper.  Then move to the Apple and run
the color bars program and adjust the Apple "hue" control for
proper colors.

In general, this control will never need adjusting after the
Apple leaves the factory (unless someone tweaked it ;-).
