None of buttons work on Kenwood KDC-519?
 
                I have a cd in my car cd player and was playing it, then I hit the source button and turned off the stereo, now it will not function.  None of the buttons work. I have tried pushing the reset button and that does not change the  situation.  No eject, no radio no display although it is backlit, nothing. Help.  Any ideas?
