Hello everyone. Thanks for having me. Around last Father's Day, my wife texted me telling me that the local Salvation Army had a Star Battle cocktail pinball machine for $40, sold AS-IS. I let her know I was interested and met her there to help load it in her van. When we got it home, I looked on our local Craigslist and found a guy that services arcade machines and sells parts. He set me up with balls, lights, and rubber rings. Other than a little adjustment here and there, the machine works really well. My wife even suggested we put it in the living room where it gets played every day. We love it so much that I recently placed an ad back on Craigslist looking for non-working pinball machines and had one reply, which is where the OXO machine in the title comes into play.
The story as I was told goes like this. Someone found this machine in very poor shape in a barn. Someone (maybe the same someone that found it, maybe not) got it working and added wooden legs due to the condition of the cabinet. It was then sold to the guy that I got it from. It was supposedly working when my guy bought it but after taking the backbox off, moving it to his house, and putting the backbox back on, the unit is stuck in reset mode and doesn't appear to have any power to the backbox. This is where I come into the picture.
I have been a tinkerer all of my life. I learned to solder when I was five. I love working on electronics. I love repairing broken things. I love it even more when someone else has had a go and failed. I’ve been repairing LCD TVs for about seven years now and recently put a 6-speed manual transmission in a Honda Odyssey to avoid having to deal with the very fragile automatic that was originally installed. I am a quality engineer with a background in manufacturing. I feel like I am more than capable of repairing this machine if I can wrap my mind around what’s going on in there and what is supposed to happen at startup.
Admittedly, I haven’t tested much as I’ve kinda just been looking things over and trying to understand what I’m looking at. Also admittedly, I am just starting to learn about these machines so please forgive my lack of knowledge pertaining to the names of the parts. I will figure it out eventually. I’ve downloaded the schematic as well as the instruction manual and am trying to make myself familiar with them both. When the machine is powered on and the left flipper button is pressed, the lights along the edge of the playfield come on. After adding a credit, the machine goes into a repeated cycle of what I’m guessing is trying to reset as long as the ball is sitting in the hole behind the flippers as if the game was over (Is that the center hole?). If the ball is pulled out of that hole, the cycle stops. There are no lights at the backbox, nor is there any action of any kind in the backbox. The flippers don’t work. The bumpers don’t work. On each side of the playfield, there is a “Extra ball and 5000 when lit” hole. If the ball goes in either of those holes, it is kicked out like it supposed to be. I suspect something wasn’t put back together correctly at some point. It seems like the machine is looking for feedback that it isn't getting. It’s also possible that the guy that sold me the machine lied to me about the whole story. I’ve attached a couple videos of what I’m dealing with. The first video shows three wires that are soldered together and were just hanging in space in the backbox. The second video shows what happens when the machine is cycling. My name is John. Thanks for taking the time to read this. I appreciate the help.
