It's a waxy substance in electrolytic capacitors that melts when heated

If you can, look on the capacitor's casing. If there's a visible + and -, it's definitely an electrolytic. They're easy to replace, provided nothing else in the circuitry if fried.

It's probably the dielectric material in the capacitor. cloudbase Oct 19 #10

If so, would it be a solder -type replacement? Beartracks Oct 19 #11

Maybe. cloudbase Oct 19 #12
