That small board is not a node board, so doesn't have the flashing smaller LED. That flashing light on the node boards indicates that data is being sent. The eject / vertical upkick /scoop / Motor are all driven by node board 10. With the playfield all the way up, it's the black board on the lower right side. See if it has power going to it, and if the fuse in it is good. It's 7A slo-blow. They use the smaller from the factory, but the holder will actually take the larger fuse size as well so if it's blown you can simply replace it with a standard size fuse.
