    Did you test continuity of the fuse with one end of the fuse removed?

    Perhaps the power wire, red wire with black stripe (J133-3) came disconnected from one of the coils under the playfield.

    Check and see if you are getting voltage at any/all of the solenoids not working (or just short the transistor to ground and get one to fire). If you have voltage at the coil then I would check the driving IC (U4 I think?). I've found cold solder joints on this chip as well as connectors going to the low voltage solenoids can cause all of these to not work.

    I think is chip LS374
