A:AnswerPut a CD in it and push "play".
This is not a troubleshooting forum for your very old product - the dx-700 doesn't even have digital (coax or optical) outputs.
A:AnswerIf you have it on random it will shuffle play. I know that if I play standard from Disc 1 to Disc 6 it will stop at the end of Disc 6. It might continually play with shuffle but I have not tried it all the way through on random play
A:AnswerMy unit does the same. I’m blaming the display shelf which is slightly off level. I will remedy that and hope it helps. My old Yamaha carousel rarely skipped.
