That was with color normal. Here is color normal, then color at 0 for the same spot.

I see all three colors on the original line and the echo so convergence is ok?

I do wonder why the service settings were so messed up. Maybe someone was there before me. Looks like blue cutoff was way up for some reason. I also wonder if the default cutoff values being much higher (128 vs 90s) will negatively impact the tube.

Probably unrelated, but the set also has an occasional quiet popping noise through the speakers.

Your convergence is decent. What you have is ringing in the monochrome channel that is also being decoded into color noise creating a faux convergence error.

That's good, I'll just leave it.

The occasional popping noise I suspect might be a capacitor in the video detection circuit, because I noticed that when video is disconnected (RCA connector unplugged), audio mutes as well. Also, the pop doesn't occur in RF mode.
