My wife's 2010 R/T had the same thing happen a few days ago. Screen is black and approximately every 30 seconds the Dodge Ram symbol appears on the screen for a few seconds and goes away. The light around the on/off button is illuminated like it is on. I have no clue on how to address it. Her cars warranty just ran out 4000 miles ago. Crazy how stuff like this seems to happen after warranty is up. Have you found any solutions?
