my issue has progressively got worse. See the image, none of the playfield lights - except GI are working. Some of the interactivelights, like the mixmaster, will turn on when they are supposed to but everything below the playfield is off when it should be lit like a christmass tree once the machine starts up and during the game.
When it first started happening, roughly one out of 10 times i started the machine, they would not work. I discovered that if i left the game on and alone for about a half hour, they would just start working. Now, 100% of the time they are out and leaving the machine on makes no difference.
I'm replacing 1 bad connector on the interconnect board for the backboard GIs thats burnt, but thats the only visible issue i can find and not related.
Any advice? I did the quick transistor check and they all tested ok.
