Today, in attempts to start the unit, the sequence is grey screen "you've come along way survey", the victory song, home screen opens up. Everything, including the hard buttons are for the most part unresponsive. After 10 seconds it flashes and goes back to the "you've come a long way survey" screen, remaining at that point indefinintely until powering off. No ability to connect to remote access. Any suggestions that may work? Unit worked fine the day before.
