I have a South Park pinball machine that has worked great for the month I have owned it. When I bought the machine I replaced the 3 AA batteries on the board and did a few other maintenance upgrades such as all new bulbs (LEDS from coin taker), replaced the flipper parts, swapped the chipset to profanity version and replaced the balls. Everything has worked well. Today out of the blue I plug my machine in to play and it reads something like "high power disengaged, coin door open". the door was closed and locked. So I opened the door and closed it again...nothing. I unplug the machine and plug it back in..fires up as normal and I play a game. While the machine was still on I decided to open the door to see what would happen....NOTHING. It did not sense the door being opened. I have unplugged and plugged in the game a handful of times and nothing has changed. Game play seems normal but it wont sense when I open the coin door now. I have tried manually pushing in the 2 white door switches inside and that doesnt change anything. Anyone have any clue what the issue could be? I see no loose, damaged or broken wires. Door switches are smooth. Im pretty mechanically inclined but I am clueless what the issue could be. Any help is appreciated.
