Pioneer PD-F805, trouble moving from one disc to another

Hi friends, I have a Pioneer PD F 805 cd player. The player is working well, play, stop, random, rew, ff. But it has trouble moving from one disc to another, sometimes it freezes on a disc, then returns to its starting place, and does not move again. I saw the manual and I think it may be the IC CXA 1372 Q since it is in charge of the servo motor. What do you think or will it be another component, thank you.
