Started having a problem with my TAF not recognizing the skill shot. Checked all the switches from the outhole to the shooter lane to the outhole for the skill shot and they are all working appropriately per the switch test with a real pinball, (not just with my finger) When the ball hits the outhole for the skill shot the outhole plunger ejects the ball so i know the switch is detecting the ball, it is just not scoring the skill shot. unplugged and repluged in all the ribbon cables, still having the problem. all the switches pass the switch test and the switch for the skill shot is working appropriately especially as it will trigger the ball eject. So since the signal is clearly reaching the board but the board isnt registering the shot, can i assume that either the rom is corrupted or the cpu board is bad? The diagnostic lights on the cpu board are lit appropriately per the manual on startup and during game play. any help appreciated

all the switches are working. i tried firing a ball up through and all the switch test check out appropriately. Bad ROM or CPU board?

ok thanks for the help. I figured it out for anyone else who runs into this problem. I checked the switch levels and saw that the right slingshot switch was closed, which is interesting because it wasnt firing the kicker at all, but during a game it seemed to work normally, maybe both switches have to be closed? anyway fixed that and still didnt work. I spent the next hour checking the shooter lane and thing eject switches which is far as i could tell were working properly. decided to record a video of what the game was doing to post on here and as i was reviewing the video to post noticed that graveyard value was popping up on the screen anytime the ball was ejected into the shooter lane. Then realized that the blue popbumper was firing everytime the ball was being ejected into the shooter lane. I guess the vibration of the ball eject was causing the popbumper switch to make contact and delivering a score which then negated the skill shot. Increased the distance of the pop bumper switch and everything works! Thanks for everyones help!
