I had a bit of a weird experience yesterday with my LoV and was wondering if anyone had any insight on things to investigate (I'm guessing a loose connection somewhere).
I was in the middle of a War on Land (Jotnar) and had two balls locked in the ship. I managed to tilt (oops) trying to save and it ended the ball as expected (don't think it was a big move, but was already on warning 2). When the ball drained, it didn't seem to register and kept counting down the Jotnar timer until it hit zero, then the game was just frozen.
I power-cycled the machine, but when it came back it seemed that none of the coils were working (no flippers/trough/scoop/lock post response either through tests or in a game), so I manually removed the two balls from the ship and put them back into the trough. I also noticed that the opto in the trough didn't seem to be counting the last ball, since I was receiving a "ball missing" warning in the menu (though it looked powered on). An additional power-cycle didn't change anything.
In the end, I turned off the machine and figured I would look at it later in the day, but when I came back a few hours later, everything was working and responding as expected. Any ideas of things to check to possibly prevent in the future? Apologies in advance if I'm using the wrong terminology or if this something I could have looked up in the manuals.
