I bought this player new around 1996-1997. Tonight is the first time in at least two years that I've tried to use it, and we have moved since the last time it worked.
I can't get the main drawer to open. When I press the "LD" button, it makes a spinning/whining sound for awhile, then the CD drawer opens. If I press the "LD" button again, the CD drawer closes, it makes the spinning/whining sound, then the CD drawer opens again. If I insert a CD, it makes the whining sound, refuses to cue up the CD, and the CD drawer opens again. The display shows the error code U1. "Troubleshooting" says that's due to a bad or incorrectly loaded disc, but it shows this error even if there's no disc in the player. Suggestions?
The kicker here is that I once had two LD players, the other one being a CLD-M401. It required manually flipping the disc for Side B, but in other respects it was a superior player. I used it for several years as a CD player in an audio system, in which role it worked perfectly. When we had a garage sale before moving two years ago, I sold the 401 -- a mistake. Anyway, the 504 is the one I still have, and I'd like to fix it IF the fix is cheap and easy.
