Hi - I have a Nishijin O&Y 5&15 "Obake" machine. It looks/sounds exactly like this. https://www.youtube.com/watch?v=aBfHO1t3rmQ Immaculate condition and very light usage. When I turn it on, the lights all come on and a relay or solenoid clicks. But when I turn the actuator knob, nothing happens. There is a "zero" showing in the error indicator box. Does anyone have any idea where I should look for a solution? Thanks!! JimPachinko back.JPGPachinko Front.JPG
