Quoted from Anony:I think it depends on if they use any proprietary parts, which I'd think is unlikely, and what the issue is. Some issues can be tracked down by checking component by component for the problem part but a lot of the time you need a schematic to know what each part is supposed to be doing.
It also depends if any of these boards are layered. If they have multiple layers the repairs become a lot harder from what I've seen.
If someone can get a hold of the schematics it would probably go a long way to get repairs going.
All the way at the bottom of the stern support page there's pdfs for a bunch of node boards and some have schematics.
This is the page I'm referring to: https://sternpinball.com/support/
Couple random schematics:

There's several more besides those.
There doesn't seem to be nearly enough links on the page to cover all the boards but I've never gone through them to try to ID everything. It's possible there aren't as may different board designs as I imagine or maybe many of the boards are just minor variations to a few core designs. They seem pretty straightforward and random major components I've checked are all commodity things available from places like mouser, albeit some with nasty lead times right now but I'm just a through-hole hobbyist. Maybe someone actually able to do surface mount stuff will look at them and tell me how wrong I am.
