I recently had my DM set to tourney mode. After a while, I switched it back and realized while playing that the number of combos to light first extra ball had gone from 12 (factory setting) to 14. Went into the settings menu to check and it was still showing 12. Reset it to make sure and it shows 12 but when game starts it still takes 14. Anyone else encounter this problem? Not sure how it relates to switching back from other mode as it was only taking 12 combos while set in tourney mode. Also, I'm having trouble with the knocker. Since I got the game, the knocker has been sporadic in its noise making. When I ran the menu test on it, it works great. However, during game play it is much softer or doesn't strike at all. I changed the coil sleeve and replaced the plunger with one that had the nylon tip. It would fire but not knock, so I put my original plunger back in and it worked again, but still seems like if anything is happening during game play, it doesn't knock properly like it isn't getting enough current to properly fire the plunger and the knock it muffled. Thanks for any help.
