I just opened my back box and checked mine out vs. the pics you have displayed. as far as I can tell, the ribbon cables seem fine. I know I put one of mine in backwards when I installed mine and it didn't display anything until I righted them. Not sure about the flashing led in post #9 as I don't have a board in the location you described in mine. Is that a power board? I can't tell by the pics. The Color DMD crew is great and will help you until it's right.
