Macintosh Portable Won't Start

What might be malfunctioning? The computer had rust damage on the inside and I ultrasonically cleaned the board, but it still does this. Any idea of what components I should look at on the board?

I've attached some photos of the top side of the board if anyone can see anything I might have missed:

None of the traces looked that bad to me; is it possible a component may be damaged? Such as a triac?
