I know that it's most likely Z14 & have replacement ICs & sockets, but I'm curious what the symptoms of the tilt switch closed error are.
I turned it on with the playfield up so I could check for smoke in the cab & the lights came on & the display showed 'Tilt Switch Closed' stationary in the first row & 0's in the bottom row with nothing in the credits but the solenoids didn't reset.
Later I put the playfield down & when I turned it on the solenoids reset, all the lights came on, including the chaser lights, the display behaved normal & the gameplay music played, although it shouldn't have. When I pressed the start button, the display said 'Tilt'. I turned it off & back on & 'Tilt Switch Closed' came up, then it beeped & 'Tilt Switch Closed' scrolled across the top. This repeated.
Is this normal behavior for that error, or did I eff up something else?
