Did you check the ground wire and make sure it’s not smashed in somewhere causing a short? It’s possible for it to be a wiring issue and not a board issue. Follow the ground wire for that solenoid all the way back to the board.

Did you use a multimeter or a logic probe to test U19? I’m also dealing with a system 11 giving me trouble with All of the A side coils. I found a fuse under the playfield at the far left back side hidden under thick wires that was blown. I haven’t put a new one in but that is definitely connected to my problems and may be connected to yours
