Assuming the light bulbs and fuse are good.
Are you getting voltage at the light bulbs?
When checking for voltage at the bulbs, do you have the game board plugged in? Are you getting voltage at the bulb with the original pcb and the new pcb? Depending on how they wired up the bulbs at the coin door, the pcb may have to be plugged in to the harness for the bulbs to get voltage. For example, the GND wire for the bulbs maybe wired to a pin on the harness that is not connected directly to GND. The pcb acts like a jumper to complete the loop. Maybe the new pcb GND pins does not bridge together.
Just a thought.
