My guess is that you have a short somewhere and that all of your old boards in fact are probably ok.
This happened when you were changing bulbs.....before you did that everything worked 100%..correct?
Did you lift the playfield when you changed the bulbs? Did the problems start after you lifted the playfield?
I am guessing that you have a something shorted...... a switch to a coil or a lamp to a switch.
Look for pinched wires, loose wires and anything out of place underneath.
You have all brand new boards, your problem HAS to be wiring or some hidden fuse block..maybe a wire came loose from the power supply under the table. Something like that.
When you do discover the problem, I will buy your old Gottlieb mpu and driver board if you want to sale them.
Good luck.
