Not even 24 hours on the layout and one of the LEDs went out, and by one, I mean all the green ones on one side of the car. All others work fine. All wiring seems okay; haven’t touched it since putting it on the track. Worked fine last night. See pic attached.
It is still new enough that I can maybe send it in for a repair under warranty, but I’ve never done that before.
Any advice in the meantime?
