Quoted from srcdube:I don't know much about Flash Gordon... is it Bally as well and using some of the same circuit boards.
Yep Flash Gordon has the same Bally boardset as Paragon except for the later gen sound board.
Is the tilt switch under the playfield (usually next to the flipper mechanisms and looks like a slam switch) working ?
Have you run through switch test mode to see if any switches are reported as closed (even when balls are removed from the outhole and all drop targets are reset up)?
Can you post clear pictures of the tilt boards in the cabinets?
