Yeah that board is a hot mess and the corrosion is probably the issue and it will only get worse. Consider replacing it, you can them for like $200. I'd just replace it for an easy and quick solution, and it's relatively cheap for what you get.

If it weren't for the board my suggestion would be check every switch in the slam tilt column/row as it's probably shorting.

That probably IS the reason, except that the short is in the board not the playfield. Either way that board needs repair or replacement.

Don't be annoyed or upset, it's not the end of the world it's just pinball and this is what pinball does. I've lost count of the 90s games I've gotten in with a board that looks just like that. If I'm not buying from a collector, I expect it now. And even if I am buying from a collector it's still like 50/50.

Quoted from Jakers:

I was afraid you guys would say that. I think I was trying to talk myself out of the inevitable. Unfortunate, but it is what it is.
I do have a DrWho, World Cup 94 and a Bram Stokers Dracula. Could I swap MPUs with one of them just to confirm? Obviously I would have to swap game ROMs as well but is there anything else?

No, those are all a different earlier board system.

I don’t know what you need to confirm. 100 percent that board needs to be repaired or replaced.

Also spend a few bucks on a chip puller, which you will probably need depending on which new board you order.
