I recently bought a black hole from someone who said the game worked prior to moving it, but now it doesn't. I know this is the classic excuse, but I'm relatively handy with pins/arcades so I took the chance. This Black Hole has the PI80/x4 mod install. All connections appear to be good. However, when I turn it on, it says there's a slam switch error. So I soldered the slam switch together. It STILL says there's a slam switch error. Every time I try to start a game, it makes a noice and flashes "GAME OVER". The knocker goes off, but no balls are ever kicked out. I'm at a loss on this one. Does anyone have any ideas?

When I enter the switch test, none of the other switches show closed. This is why I'm so frustrated with it. Everything SEEMS to be fine...but obviously its not.

Ok. I took a video to upload, but it won't let me. Taking the balls out had no effect whatsoever. When I first got it, it would say "oh no" when I started it, which makes sense since it's throwing the slam switch error. However, now it doesn't say anything. It just won't start. The credits always display 99, which I'm assuming means it's set to free play? Also, it cycles through balls 1, 2, and 3 on the counter immediately, but the ball kicker never fires. I also tried dropping some of the drop targets because I remembered it showing that as an error when I first got it. However, it still seems to test all switches as fine. When I go to the switch test, it flashes three dashes, then tells me which switch I hit. Should I hit one. I tried resetting it to original settings and it went back to saying "oh no" when I try to start a game, so at least that makes sense. I have no idea how to fix this. Anyone else have this board and have this issue, or know a good number to call for support?

I sent a message on their website. I'm hopeful they'll be able to help me get this fixed! Thanks for all of the suggestions!
