If the player is original, then you would have a philips CDM3 or CDM4 in there along with the associated mechanism controller. These players are long obsolete and parts to repair them have long since evaporated into neverland.
If your player is original then you must buy the player upgrade kit. The correct kit to order depends on the model of player presently installed in your machine. The kit includes a bunch of new parts: new mech control circuit board assembly, new player assembly, new wire harnesses, some new mechanical parts, and a new power supply board as the new player requires different voltages. The kit updates you to the latest Philips CDPRO2 player. Order the kit through the parts department of any Rowe distributor. There may be a distributor near you:

Here are the kit instruction manuals so you can see what is involved:

It's drop in plug n play compatible. If you have a CDPRO player, it can be repaired. Parts & repairs can be gotten here:
