The first thing you need to do is to clean the area well to remove all of the soot so that you can see the traces in the area. Photograph the traces so that they can be repaired if cut. Then cut away all of the badly burned (and likely conductive) fiberglass. After the conductive material has been removed, then you can begin troubleshooting.
This often happens to amps when the terminals aren't insulated well enough from the board and an arc forms between them.

I agree with Perry, unless you can repair that area of the board that is fried I would consider this one a dead Jim. Looks pretty bad in your picture...
