Not even sure what "ACC" is in this case. It sounds like "Automatic Color Control," which would control the strength of the colors, not the color oscillator lock or wrong hues.
Also not sure what the "burst line" is unless you point to it on a schematic.

If you could link to a schematic and service manual, it would probably become instantly clear.

Finally a hint about VK: starting a new thread about a problem that apparently has been discussed to some degree in another thread is not a good idea.

Yes, I know about multiple posts, but I felt that maybe the title of the current one is keeping some from viewing by thinking it's only on that topic.
