I have an old Williams Laser Ball and the right kickback is not working. This being my first and only pinball machine, I'm fairly new at this. After examining the corresponding coil, I found it had melted somewhat and the coil sleeve was frozen. I replaced the coil and sleeve and I replaced the corresponding transistor (T8 I believe) that was clearly crispy.
Unfortunately, it still does not fire. It's not locked on and I don't see any blown fuses or other obvious damage to the board other than some cold solder joints which I touched up tonight. Still no kick though. What's my next step?
