Quoted from Schwaggs:I would replace the diode on the coil (not the switch). Pay attention to the orientation of the wires and the stripe on the coil. The diode on the coil is there to protect the driver transistor.
Then repair the transistors on the driver board.
No luck after changing that diode and the two transistors.
Two other issues I wanted to ask about;
When the ball goes through the F lane the score and noise register but the letter doesn't register. When you lite other letters you can lane change to light the F and it will still award Fire and the multiplier when you lite all four.
The other issue I have is the power target in the middle when hit, lites the one to its left. The left target when hit will lite and register as will the one on the right but the middle will never register or light. I changed the diode on the middle target and the F lane.
