I just got a chance to blow up the pic of your driver board, and it appears to have some whitish looking residue in between the black caps.
This could be water damage that may have cause the fets to fail. I suggest that you clean that part of the board with acetone and or alcohol till its clean using a small brush and or q-tips.

You might get lucky and solve the issue of why it failed, and get by with just replacing the Fets, cross your fingers and maybe luck will be with you>

Please correct me if my picture software is fooling me by displaying your picture with incorrect hues...

Good eye, You are correct.
It was used on my boat so moisture sure did get to it. Looks like just that area for the most part. I will clean it.
I will order the fets this week. Thanx
