MK131 Traffic Light Kit

Picked up one of these for my daughter, it is her first kit. I suspect she may have overheated things and lifter some pads, as the lights are not doing what I expected. Is there an off cycle on this where all the lights remain off? We see the lights go through a cycle, then turn off.

Please advise.

No, it should behave like a regular traffic light, i.e. green - orange - red - green - …
Check orientation of all diodes…
Good luck!
