Just had the same problem in one of my games. Game boots up and goes into attract mode but has many burned out bulbs, which I didn't think much of as this is a project game. All playfield switches dead, solenoids work in test mode but not during a game. Swapped around U10 and U11 with no change. Hmm...., looked inside at the tilt plumb bob and this is what I seen. Needless to say with the hook put back where it belonged the game is now playable, so what I'm saying is check the simple stuff first as you never know. Plus I never saw the tilt light being on because the bulbs were burned out. Anyways, that's what fixed my game.
