You might have gotten off lucky, sometimes the crossovers will blow a capacitor (or other cheap passive component).
I'd eyeball them for obvious signs of an overheated component as a first step. FWIW, the first time this happened to me I paid $75.00 for repairs & the second time I noticed which cap was blown and bought a new one for less than 2.00.
