When you see those traces of 'wrong color', is it all of one color, like green (or purple)? In any case, it sure sounds like the reference oscillator is not running.
Since you are seeing traces of color, it indicates the CK circuit is being keyed 'on' by the burst signal. If the burst signal were absent, the CK would remain 'off' and you'd see no traces of color at all.
(The purpose of the CK is to prevent colored hash in B&W broadcasts.)
