You didn't even have to specify the "C", as the F and C scales meet at -40.
I experienced that temp once in Midland, Ontario. We get close here in
Wyoming.

I tend to agree, and if a cable tech was lurking around lately I'd be
suspicious.
Of course the question would then become why a problem on only one
tuner, but there might be enough variation in tuners that the problem is
still outside your box.

Having suggested it I'm ashamed to say I don't know, don't own a 500,
but I've seen reference to it here.
