Where's the issue(s) causing these

Modern sets have a color killer circuit that prevents this:

The explanation here describes how Israel held back on color tv and what viewers did to counter it. Never underestimate the determined viewer.

Those are calibration patterns from the Video Essentials DVD. They effect is also seen with all overlay video (onscreen displays, etc.). It is also showing, but much more subtle, in some video scenes.

I adjusted the color killer as described in the SM. It said to turn to static channel, adjust control until there is color in the static and then back it off until there are no signs of color. I did this once and noticed that there were occasional bursts of color, so I backed it off a bit more until that no longer happened. Should I try to back it off a bit more?
