The fuse in your photo (glass with white middle?) is a 120v fuse for the 120v input to the board right by where the 120v cord has its three wires attached inside the unit. If it is blown -no input and no output. You can check for 120v voltage on the other side of that fuse.
You can jumper that fuse end to end and see if the unit then works. Or it might work for a second and then smoke from whatever blew that fuse if internal cause.
EDIT--You cut the 120v plug to hardwire it ISTR. So that means you could have shorted the input where the plug was cut off--which would have blown the glass fuse? If so it was external and it should be safe to jumper the fuse with the cord wires repaired? ISTR you said water got in there?
My converter has only one 120v glass fuse at the input, not two. Hmmmm.
Here is a photo with some info from a thread a while ago--scroll down to the photos of the 9280's board and some info about its fuses.
