Score holes not scoring:
Each hole has an optical sensor that reads the ball passing through the hole.
This sensor is programmed to make noises as the ball passes through.
It will make ding noises corresponding to the value of the hole.
Example: The 10 point hole will ding once, and the 40 point hole will ding 4 times.
Play the game and verify that all holes make the ding noise from the speaker the correct number of times.
You might have to turn the volume up on the main board to hear the dings clearly.
If all score holes make the correct number of ding sounds, then continue to
Flip Display Not Working

There are two separate areas that could cause the game to not score correctly:
1.) Score holes not scoring
2.) Flip display not working correctly
The flip display will show the value of the hole scored.
It has a home sensor and encoder sensor to keep track of where it is.
To test:
Turn off power to game. Wait 30 seconds. Turn game ON.
The flip display will flip around and stop at zero.
If the display keeps flipping:
The Home Sensor is not seeing the home notch on the assembly.
Make sure wire is secure on the home sensor.
Follow cable back to main board and ensure the
wires are not damaged. Part #’s: AACE7204 , AACE7224
If the display stops flipping, but stops at 10 or 20:
The motor is turning too fast and not stopping when it sees the home notch.
Turn the power supply voltage down on the small dial on power supply.
Play game and watch the flip display as the ball scores - if it flips too far:
The encoder sensor is not seeing the notches around the outside of the display wheel.
Make sure wire is secure on the home sensor. Follow cable back to main board and ensure the
wires are not damaged. Part #’s: AACE7204 , AACE7224
Replace sensor if needed. Part # A5SE0001
Turn the power supply voltage down on the small dial on power supply.
