Check all your connections again. Pull the plugs from the board and eyes and plug them back in. Check for loose wires, that sort of thing.
If that doesn't work I would consider seeing if you can borrow another board for testing purposes and then going form there. It may be the board itself but that should be a last resort kind of thing.
Also you can do the camera trick on the eyes, since I assume you don't have the laser eyes. Take a digital camera or the camera on your phone and look down your feedneck with the eyes on. Check for a purplish light, you may need to be a low light room to see it. Pull the trigger a few times as well to see if the eyes flash. If you see that light that means the sender eye is working. The IR light doesn't show up properly on digital cameras and comes out purple so it's a good way to see if your eyes work. I've done it several times.
