Hey all, looking for some recommendations, I got a Bally playboy at an auction awhile back. They had it powered up, all that worked was most light bulbs. It’s not in horrible shape but was the home for some mice for some time. I’m a pinball rookie but am gonna attempt a full restore on it, it will be great to see it back in great working order. When powered up I get all seven test flashes on Main board but no sound or follow up. No displays, not much else. Ill post some photos, one of the main issues is on the solenoid board there is a complete burn through on the board by the relay. My question is if I have to replace that board should I just change them all out to alltek boards or just go one board at a time once I start putting it all back together?

Thanks Tom, appreciate all the info. Do you see that burn through on the SDB between the connector and the relay, I haven’t pulled the board to see how much is damaged but that was why I believed I need to replace it. Thanks for your help.
