Hello-
I have an AIQ Pro. The following issue recurs. During the game, the disc stops registering spins, and the LEDs in the lower half of the playfield behave oddly. Either they shut off entirely, or randomly light inconsistent with what's actually going on in the game (e.g. the lit Avengers inserts don't correspond to what's actually collected). The random lighting of the LEDs often changes when I operate the flippers (??). I don't seem to be able to trigger it by shaking the machine.
In diagnostics, when the machine is having one of these "episodes," the lower half LEDs don't light when running "Test All LEDs." The disc does not register spins. Node board bus tests all pass.
Shutting the machine on and off often, but not always, fixes the problem temporarily. It always comes back though, some random number of games later.
It seems (to me) a problem with node board 8. I have replaced the ethernet cord between node boards 8 and 9. I have reseated every connection in node board 8. Neither has helped.
Is swapping the node boards the next logical thing to try?
Thanks for any insights!
