Help Understanding ACC

[old_tv_nut]

I wish I could help.
I'm afraid I'm not familiar enough with this chassis to figure out what's going on.

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.

Don't know if this is enough of the schematic to help, but just in case, here it is.

I've circled the ACC and Burst sections in red, shorted points for testing in green and the point I measured voltage in blue. If I'm not mistaken, the Burst is used for a color signal/image?
