It's possible you may have environmental issues going on (google
'chinese drywall'). Check wiring of light switches outlets, and copper
tubing in plumbing and a/c units for corrosion.

To me it looks like the normal oxidation process that occurs due to
reaction between silver plating on the connector and oxygen in the air.
The dark color is silver oxide. {Some of you chemists can better
explain this effect.}

Yeah well... the reason I found it was because I was looking for an intermittent

Well, you might have mentioned those little details to begin with, right?
From the original photo, which perhaps was over-sharpened, all of the
metal parts look like they are in some state of corrosion.

With problems of this sort, it is very important to make sure that the
TMP connectors are FULLY seated. Otherwise it is possible to have the
center pin just BARELY making contact. This will cause an intermittent
problem to reappear at the most inconvenient times possible (been
there, done that).
What do they make those things out of ??
Is that your new K3S ??

OK, I took the top cover off on the bench, and wiggled some of the TMP
connectors on the new synth boards, and viola! Rx and Tx are back.
Unfortunately, I haven't been able to find which, if any, connector was
flakey, as additional wiggling now doesn't make the issue re-appear.
So, off to the
