Okay, I really hoped not to have to come here with a problem so soon, after having my JP working almost flawless for half a year. but alas.. I need your input, dear JP owners Suddenly last week it seemed like all switches triggered and the machine was completely confused. After some switch checking, I observe this: (See attached image)
1. When slapping the cabinet, it triggers all switches in the bottom row in the matrix (marked in red). This also happened at itnervals without me touching cabinet, and the playfield up resting on te hackbox.
2. When activating the left slingshot, the corresponding row (marked in green) switches all trigger.
3. Likewise with the right slingshot and its corresponding row switches.
Also it seemed like the left t-rex movement switch was dead. I yanked abit on the wires to get them off the switch, and then suddenly it triggered again when pushing the leaf. Nevertheless I replaced the switch and connected wires, and it does not work now.
Any ideas or similar experiences?
