Apple IIe colors wrong (timing problem)

[Mitchell Spector]

Is there a way to adjust the color phase shift timing on the Apple IIe?
Oddly BOTH my Apple IIe's (different revision motherboards) do not
display colors correctly. In Hi-Res, blue is turquoise, violet is dark
purple, and green appears a sickly brownish-green. I can "correct"
this by adjusting the tint/hue on my composite displays, but found
it strange two separate Apple IIe's would have an identical problem.

By contrast, my Apple II Plus, my 3 Apple IIc's, Apple IIc Plus
and IIGSes display colors properly without any display adjustment.

On the Apple II Plus there is a trim-pot to adjust the timing, but
none on the Apple IIe. Just wondering how to correct this problem,
could there be a faulty IC or crystal affecting the color timing?

Comparing the Apple II+ and IIe schematics, it would be a matter of adding a trimmer cap across the C32 L3 3.58Mhz bandpass tuning.
See page 36 of the IIe Sams ComputerFacts. What it does is change the phase of the color burst being generated.
Or try another 14.318 crystal. The 3.58 is divided down from it.
