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!

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