Hi Guys, I had disconnected the battery for 17 hours and no change, unit still says no signal. After I disconnected the battery I presed the reset button and hold it for 30 seconds, but nothing seems to work. But it is interesting that the device after unpluging still knows where the movie finished to play, and what minute of music was played. This means that the internal memory is not reseted, because otherwise the unit would not know.
What else could I do???
