Ah, another one of those FRIGGEN tantalum capacitors.

tantalums are notorious for that as they age. they will short and explode. ive seen plenty of leader test equipment do this very same thing.

once one of the tantalums go, the rest will follow eventually. every single capacitor needs replaced, including the tantalum.

if the cap was just on a power rail, its LEAST LIKELY it has done any damage outside of the capacitor itself.
