Burning right thru the pcb for 1/2 inch around the L pin of the IEC, melting
of the plastic of the IEC above the burning and even the linecord plug

Yep, ring crack around a power solder connection, generates lots of
heat.
If you can clean away the char, do it (I've used glass bead blasting
to good effect). Paint the affected region with Q-dope/styrene
varnish/corona dope
when cleaning/soldering/flux cleaning is done.

Replace any AC fittings that look damaged, of course.
