I am not an expert on this in the slightest, but it looks like a cap or two barfed all over the board. If I were you, I would remove the offending caps, scrub the board with vinegar and then IPA, and then use a volt meter to make sure the traces are still good. If the traces are OK, then the board is probably salvageable. Would I attempt to do this myself, yeah, maybe after watching a few YouTube videos, specifically Adrian’s Digital Basement. Would I succeed? Eh, probably about a 50-50 chance. Someone with more experience should be able to save it, depending on the state of the traces on the board.
