Main flippers work fine, but upper right and right upper playfield aren't going when the right button is pressed. I think the solenoids are OK for these, they're just not getting triggered to go at the push of the button. Any suggestions on this?
Note: When you shoot the right loop and the machine does the right upper flipper to indicate that shot is coming, the flipper goes. It almost seems as if control of that flipper isn't coming back after the machine triggers it.
Thanks in advance for any help.
