Is it ghosting? Are all three or so lights the same brightness? If not the same brightness it is ghosting. If ghosting get non ghosting leds. That game is known for it. Next a diode. Test each diodes with a meter. The next thing and most likely it is the power driver board is bad. Had the same thing on a attack from Mars last night. You could test that board in another machine. If it does strange things in the other game that is your issue. Good luck.

That is my first question. Why were the boards replaced? Was it a lighting issue? If the previous board was dead. You could have replaced without fixing the problem. If so you could have just fried the new boards. The rotten dogs aren’t fused the same way. That is why I suggested testing in another game. If the RD that could be the problem as please check the above thread. If a short you can to resistance test all the way through.
