No coils at all? Did you check them all in coil test? The fuses you replaced didn't blow again? Usually F112 is a bad rectifier or capacitor

Quoted from drsfmd:No coils at all. Yes, they were checked in coil test, and neither fuse blew again. That's what I'm puzzled about. Game *thinks* it's working with no error messages.
I hadn't considered a bad rectifier- I'll have to research how to test them, as I've never dealt with one before.
They're just four diodes internally, you can see them drawn on the schematics like that, so you can usually use diode test on them. I think the capacitors on the driver board might mess with that though. Fuse not blowing suggests maybe the bride is open internally, so if you get no reading at all both ways on any of the four internal diodes that'll tell you for sure.
Check ac voltage going into the bridge and dc coming out. If no dc or anything seems suspicious, I'd just replace it, can't hurt
