I had a node board failure in my Ghostbusters. Was random and the machine was just over a yr old. Had to go through my distributor and order a new one. $230. The replacement one Stern sent me, yep, faulty out of the package. Had to perform a series of tests to prove it to them by using one that was in the game that worked. So after proving that the new one was bad from the factory, had my distributor order another. Stern “forgot” to send it until the distributor reminded them almost 2 weeks later. Got it and replaced and still ball trough error. I called support and talked to them again and was sent new ball trough boards. Presto, game back up. So my issue was a node board and trough boards at the same time. Also this is the only issue I have had since I bought the machine....just hated spending $200+ and being down for a month.
