Lights not working on a Fire

[Pie Man]

Hi I am struggling to get a certain few lights working on my Fire pin. I’ve checked bulbs connections and all fuses. It’s the few on the building in the picture.
Can any one shed any light on what the problem could be.

Picture of board under play field, have checked connections?

I reckon cracked solder joint. Take the board out, reflow solder at the connector pins.

Ok Thankyou, this would make sense, would I be able to see a crack in the solder?

Unlikely...

All the non working lights are on the GI string Green / white green

Does this go via a GI relay pcb under the play field ? I don’t know, but if so check it’s installed and that the connectors are good.

Ok so I need to trace these two wires back and see where they go. I have been concentrating
on the other bank of cables on the right hand side. Thankyou

Ok I have traced the string green/white green back to the back box board ( I assume for GI)
the solid green goes to a small board ( see picture) will I be ok putting a bulb on both these wires? Just so I can eliminate it down to the circuit board which houses the bulbs that I can’t get working.
