Could be the relay is sticking shut. Try filing the points. If you can catch it stuck with the playfield up, try to manually pull the relay open and see if it holds itself shut.

Quoted from LOTR_breath:Oh, if the magna save is relay controlled(sorry I don't have a manual) then the relay is almost certainly to blame.
The magnets are too high current for the driver board, so the driver board transistor controls a relay which controls the magnet. But OP says it goes away after a reboot, which I'd assume sticking relays wouldn't be effected by
I doubt it's the connectors. They could only make the magnet *not* come on. It could technically be an ic, but chips don't tend to fail intermittently that often. And it's only ever the magnets? The boards drive them just like every other solenoid, so I'd assume you'd have other issues.
Quoted from LOTR_breath:What about the fact that the magnets are on timers? You can adjust the number of seconds that the magna saves stay on in the menus. I guess this is accomplished with code? Or is it more of an IC timer circuit? I'm really overthinking this now, LOL.
Thats done in code but the light would be flashing while the timer is counting down
