Today I noticed that about half of the LED light boards, as seen in the pic below (all LED light test), are out on my Ghostbusters premium. I checked a good number of connectors underneath the playfield and everything seems ok. A couple flashers are out as well, the one for the containment facility and one for the pop bumpers. Neither of the two flasher that are out are on an LED board but are rather traditional socket based lights. With a couple flashers out I'm wondering if its node board related? In the node board test menu the CPU board shows up as 1.0.3 or something and all node boards are at .20, nothing came up in the node board test menu regarding errors. No technician alerts are present in the game either. Reinstalling the latest code didn't resolve the issue either.
I was checking some connections again later this evening on the game when all of a sudden all of the lights came back. I figured the issue was fixed and I started a game. Everything seemed fine and then a few minutes again the same lights were out. It had been a month or so since I played the game and today I installed a shaker motor on it before I noticed this issue. I disconnected the shaker motor and the same behavior was being exhibited so I don't think it's related to that.
Any suggestions / advice would be greatly appreciated. The game is from one of the later production runs (purchased last year).
