Screen flashes blue and then goes dark.

[Ghost]

So I am guessing I must have messed up somewhere but as I keep getting the same results I figured I would ask here. When I plug in my pine board the screen flashes blue for a second but then goes black. I know everything is connected where it should be though its possible all the ribbon pins aren't lined up perfectly. Should I just keep trying to reconnect them until it works or do you guys have any other thoughts?

Lock down the ribbon cable if you haven't already. Lift the black flap on the connector, insert the ribbon cable, then bring the flap down to lock it into place.

Also, that stuff xalius said.
