Turned game on this morning, like the other day it acted up for a second, then worked normally. Tried hitting playfield with my fist, no change. A few hours later in attract mode it started up....
I have the same issue and in my case it’s caused by poor a connection to one or multiple leds boards. You can track them down by going into the test menu, turn all leds on and choose white light. Check the connectors on the led(s) that have a different color until they turn white. Unfortunately you have to do this you quite often because JJP uses really poor and cheap connectors. It’s driving me mad to the point that I’m thinking of solder all led boards permanently to prevent this from happening again.
