Hi again, disregard my question about the white switches, I just had a quick look and found the other slam tilt switch on the door, I never even realised it was there, so thanks for teaching me about that one!
However, it also doesn't look like its closed, and just like the other slam tilt switch that I mentioned in my first message, if I push the switch to connect, the message on the DMD becomes ' SLAM TILT ' and then when released, after a few seconds the DMD shows the 'TESTING....' screen again, followed by the 'SLAM TILT IS STUCK CLOSED' message again.
I don't know if this might mean anything obvious to anyone, but as everyone will know, usually when you switch on the machine and it goes into its initial diagnostic test, if it finds an issue you will hear the loud BONG - BONG - BONG - BONG sound and a message to press the enter button inside the coin door to see what the issue is.
This is not happening here. On start up it shows the diagnostic testing screen, but then just immediately shows the 'SLAM TILT IS STUCK CLOSED' message, no BONGS, and no use of the enter button. None of the coin door buttons respond, and the only thing that changes the message on the DMD screen is pressing closed either of the slam tilt switches.
Does this sound familiar to anyone?
