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.}

Note: The connection is purposefully disconnected to show the
corrosion inside the socket.
And no, I don't live on a tropical island. The average RH here the
desert of Tucson is less than 20%.

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

there, done that).
If all you did was to wiggle to fix it, then at least one of those
TMPs is NOT fully seated. You need to check them all again. Note that
most of the barrel beneath the fins is in the socket when they are
fully seated.
Rotating the TMP just a little as you push in is sometimes useful.
Good luck and may you not flounder around nearly so bad as I did :>)
