Look at the red wall in the upper left of this one and you can see the chroma dots in the red area quite plainly:

I’m certain I see what you’re referring to. I do have a SMPTE color bar signal. Okay, will put my eyes on it. Will try the adjustment both ways if necessary. In a few weeks after the adjustment, plan to post a few “Kiss Me Kate” screenshots.

When viewing them, they will be moving, not stationary as in the snapshots. It is important to view a large flat area of color. That's why color bars are best. Variable areas and edges generate sidebands that produce dots that cannot be nulled out by the trap. You will always see some dot crawl on edges. If you have an oscilloscope, you can look at the luminance amplifier output and null the "fuzz" caused by the subcarrier.

That is very helpful. Thank you. No scope. Those dots are in just about every shot. Would have never known. I thought what we are seeing as normal.

Just want to add: In the nightclub scenes, Marilyn’s dress is orange, not red.

I went looking looking for Kiss Me Kate, but the stores only had the BluRay version. I have an inexpensive DVD player hooked up to my modulator. I order a copy and will post the screenshots later.
Gone With The Wind on a 21CT55 with a 21AXP22 photographed May 6, 2018. See this shot and 8 more in full resolution 6000X4000 at this link: https://visions4netjournal.com/2018/...-carousel-4923 It is impossible to see those dots that Wayne talked about on a moving live screen (with my 72 year old eyes).

No, this is not a HD shot. It’s Vivien Leigh as Scarlet O’Hara in the 1939 film, Gone With The Wind, photographed May 6, 2018 on a 63 year old television.

My only comment at this point is that the shadows in many shots look blue. What does a gray scale look like?

The grey scale is good at this time. It may be slightly cold. I think this has to do with the movies color balance itself.
If you look at Gone With the Wind, the shots look consistently warm.

Hmmm. When I look at the picture of Scarlett in the straw hat, I see warm highlights, but blue shadows (her hair). Before you ask - my monitor is properly calibrated.
There also is something strange in that the blue black level seems higher toward the bottom of the screen (it's less cut-off). |

Just had a thought - the blue DC restorer may be weak. This would cause the blue background to drift the opposite of the dominant color and possibly vary over the height of the picture. You wouldn't see this on a grayscale pattern.

Perhaps it’s the green gun output. It was poor to start with. Grass looked amber. We corrected that. Now the plantation shot shows a nice green grass, but it is not as strong (green) as the CTC-7. Scarlett’s scarf in that shot should be greener.

A weak gun will affect mainly highlights, not shadows. This appears to be more of a tracking issue where the blacks shift towards blue on some scenes, which points to a DC restoration issue.
