Question about Pioneer PD-M423 CD Player

2 Answers

Pioneer PD-M423 CD player will no longer read CD's. For each CD, I hear either a high-pitched buzz for a few seconds, or 3 clicks, then it moves on to try the next CD. Unit was recently moved several hundred miles by truck. I already checked the laser lens per Robotek's solution, it's still in place. There are no loose parts inside the unit. Any suggestions?

Have the same problem. Had friend, electronic tech look at it. Pickup assembly failure. Use Partstore.com or Pioneer to find part and then cross reference with other models that use same part. I bought used item on Ebay, $40 to repair my unit. Simple 5 screws, two pug in cables. Be sure to discharge static electricity from body before touching interior parts. Up and running in 20 min,

Pioneer model # PD-M423 won't read the CD and ejects it.


If it is with all clean cd's then it can be a dirty lens which you can buy cleaner for, but i've read the manual and was dated 1993, so if a cleaner not helps , it's the unit itself and time for a new player. Parts are very expensive and it's one whole unit..... I think it's the end.

Turned on my Pioneer PD M501 one day and it would not play. Disc tray will not retract into cartridge and cartridge will not eject.


Sometimes the little ball bearings that keep the cart trays separated come out causing tray jams.
Make sure your tray retracts all the way into the player flush with the face plate, gently push it in while retracting for those occasional no-read situations. (Also for Denon that takes these same carts). Also note that the CDs go in the Upside Down position.

Can't remove cd cartridge because won't power up.


With the top off the unit, you can turn the tray gears manually for slow eject function. Unplug unit before touching anything inside, check internal fuses.
Sometimes the little ball bearings that keep the cart trays separated come out causing tray jams and shorts.
Make sure your tray retracts all the way into the player flush with the face plate when loading, gently push it in while retracting for those occasional no-read situations. (Also for Denon that takes these same carts). Also note that the CDs go in the Upside Down position.

Cd player


pioneer cd players have the common problem of losing their laser lens due to the glue that holds it in place going brittle over time. try shaking the player from side to side and upside down to see if you can hear the lens rattling about. if you recover the lens, very carefully slot it back in place and apply a tiny drop of glue (NOT SUPERGLUE) to the outside edge of the lens taking care not to get any on the focus area and leave to dry. all should be well after this. i find UHU GLUE in the yellow tubes do a lasting fix but don't use SUPERGLUE as the fumes will coat the lens.

hope this helps?
