If you are seeing the no Trutrack found error message or having trouble with shots not registering it could be due to a loose processor chip.
You will need a small pair of pliers, or channel locks, and a Phillips head screw driver.
1. Remove the TruTrack board from the floor and flip over
2. Undo the legs of the board and expose the circuit board
3. Tap on this and press down on it
4. Reconnect the circuit board to the frame and place TruTrack back into the floor
