my question is, just built the mk4s kit and turned it on, screen is blank...checked, checked and then checked again all the connections, compared to the pictures, walked away, came back did that again, and now I'm here... tell me this is a common stupid mistake that everyone makes, or tell me how to make my screen come on. thanks
