Question from Dan: Ok, I have a Dig Dug board question. I cleaned all contacts on board like your video said and I plugged it back in but there is still no monsters showing up. They are invisible, plus the main man is now semi invisible. All other colors and graphics are clear as a bell. I have only seen one black spot on board by the main plug in. So my question is where do I go from here to see why they are invisible? Any help would be appreciated. Thanks, Dan
