Quoted from manadams:I have a two day old BM66 that the lower GI has completely gone out a couple times while playing a game. Power cycling is has fixed is so far. Have opened a ticket with my distributor and waiting to hear back.
I had an issue with the lower GI going out on batman66 and I was getting a node board error. I thought I had a dead node board. I called Stern and talked to Chas. He told me I had a shorted bulb. I guess the system detects the short all the lights go out like a Christmas tree.(WOZ???)
He basically told me to take the bulbs out and try them one by one to figure out which was bad. Replaced the bad with a good one and all the lights returned. May not be the same issue but if it helps someone I figure it’s worth mentioning it.
