You could have more than one thing going on, so let's try to clarify:

1) What is the source of the menus in post #14? Is it an internal menu from the TV, or from an external device? If internal, this may be a separate problem with the menu video injection (separate from the chroma delay you see on external sources).

2)The external sources you have shown so far all seem to have the chroma delayed compared to the luma. Maybe a luma delay line problem, but I would think if it was a bad delay line, the luma frequency response/transient response would be messed up.
Some external sources may not have the luma/chroma timing adjusted to NTSC broiadcast specs, so if the luma delay is a bit short on this model of TV, it will be made worse. [NOTE: NTSC broadcast transmitter specs include an envelope delay filter to delay the luma with respect to the chroma sidebands. This was specified to match the flat sharp cutoff IF amplifiers of the original receivers. Later, manufacturers found it better to use a "haystack" IF response, which did not match the transmitter filter. This was compensated by using a slightly longer luma delay line in the receiver. This chassis may simply use a slightly short luma delay line, the effect of which is made worse by the lack of a lack of envelope delay in common sources. Unfortunately, there is no analog station on the air that you could use to check.]

3) Have you tried to see if it changes significantly with fine tuning? [Thinking IF alignment or chroma alignment could be part of the issue.]
