Several odd and intermittant problems have started on my WOZ.
Even though "collect" is lit, Haunted Scoring does not activate. Checked switch in test mode and switch matrix connectors on the main board. No obvious issues there. It fails to collect more now than it awards a new mode.
Without the ball being in the VUK or on the castle playfield, RESCUE will randomly appear on the screen as if the ball was up there.
On certain times, and I have not figured the pattern out yet, a ball shot through the doors on the castle playfield will not be ejected. A ball search must happen to get the ball out. Seems like a software issue.
All connectors seem tight.
