I thought that I had the same problem. I then discovered that when I put 3 CD's in it started up on it's own. If you push the demo button you can see how it's supposed to light up the number of tracks in a square on the right of the display. It wasn't doing that until I put in all 3. Then it started up and I was able to use the disc 1, 2 & 3 buttons to change from 1 CD to the next and I used the Up and Down buttons to change songs and the play button above the tape deck is multi-functional. Hope this helps.
