Quoted from john17a:checked oue ribbons ans also all fuses have not been replaced coils still being powered up locking on
Please explain. You have not replaced the blown fuses and you still have lockked on coils on power up? Did you replace coils, have you verified the wiring, are there wires exposed and touching metal, did you re pin connectors, are they re pinned correctly?
Quoted from john17a:checked oue ribbons
Did you reseat them?
Another possibility is the Game ROM on the MPU is backwards.
Post some pictures of the boards with the cables connected.
Quoted from john17a:Roms not removed ribbons checked and swapped fuses removed
Need more information on what you have or have not done to the game?

J127 and J130 are all your solenoids and are driven by transistors on your Power Driver Board. Have all those transistors been tested? 103-105 are individual coil power circuits, sounds like those are your problems to start with.
