You probably blew the circuit that drops 12VDC to 5VDC which is what the board runs on. Have a look underneath the board to see if there is a blackened trace line. That's what went phutt on my board. Unfortunately, you're in a remove and replace situation. Cough up another forty bucks, bro. If this is where the short circuit happened, then everything donline from there should be OK.
