Some regulators have overtemp protection built in.
Those can survive an overload like you saw.
The fact that you have a non zero voltage says you don't have a dead
short.
You might be able to trace down the overload by measuring resistance.
It would have been better if you had a dead short, however, because then
you could use an ESR meter or low ohm meter to track it down.
You may need to start removing parts, jumpers, and/or cutting traces.
Pick a nice clear run of a trace and cut it with a sharp razor knife. To
patch it later, scrape off the solder resist, tin and solder a bridge
across the cut with a short piece of wire that will handle the current.
Try to isolate various sections in a logical manner.
Don't forget to bridge ALL the cuts!

please pardon my infinite ignorance, the set-of-things-I-do-not-know is

infinite set.

Good thought - I'll take a look like that when I get a chance. Thanks.

I will often sub in an external power supply and just see what gets hot. No
need to cut any foil runs at this point.
