Hi all - I seem to have an issue with my premium. Basically I've been getting intermittent flipper failures - sometimes during a game and sometimes they wouldn't work on startup. I reseated all he connectors on what I think was node board 8, and it was working for a while. The issue happened again so I tried the same thing - but now not only do the flippers not fire (they do work in coil test, but the switch test registers nothing when i press the flipper buttons), but the trough optos are all dead so the machine just keeps cycling through ball location search when I try to start a game. I think maybe I've answered my own question - but is this a node board issue (node 8 I guess)?
Anyone have any suggestions on what else I could check? I must say, this machine vibrates/shakes a hell of a lot so it could be another connection that's worked its way loose?
