Encountered a very odd issue today that has me stumped. I was looking at a Bally Viking that would not score the special or 50,000 points from the standup that is behind the inline drop targets. The switch test fine in the switch test but does not score during game play. I do not see a way of turning off playfield specials from the dip switches. Has anyone encountered this before?

The drops all score, the bonus multiplier advances, and the special light comes on but will not score.

In the switch test I can close the switch and it registers. Just not during game play not matter how long you hold it closed.

If it were a dirty contact it would not register in the switch test. It tests good with the drop targets up or down during the switch test.

During game play the drop targets all register, the special light is lit but will never score when the standup is hit, held closed, etc.

Both of the dip switches are set correctly.

Not having a knocker coil should not impact the game scoring the special and advancing the target to then score 50,000 points.

Correct. It just never scores the special or advances to score 50,000 in play.

It is the original board.
