Hi
I have installed new laser pickup on this player and it works but, when cd is inserted inside it takes more time than with previous laser to start playing, and when song is skipped starts somewhere in the middle of the song or 30-40 seconds of the song and continues from there..
Anyone experienced with this player and what should I do? It seems like I need to fix the focus or tracking.. Any kind of help is appreciated.
thanks

Further, it is fairly likely that you will also need to replace the platter motor(and most likely the problem all along). Yamaha used more or less the same platter motor from the CD-X1 all the way through the CDX-1100, and a nearly the same motor for several more years. These were brush motors that were EXTREMELY prone to failure. On the models that used a pressure disc clamp(which means all but the CDX-1100/1110/5000/10000), you can tell a bad spindle motor immediately by simply touching a finger lightly on the disc clamper while a cd is playing. You'd feel a slight bumping with each revolution. With the magnetic clamper, you can't really do that test, so you have to go by behaviour. Yours sounds like a pretty classic bad platter motor.

ah, and one more thing to ask you...
it is possible to use this cd-player as a DAC, using another cd-player as transport...?

It's been years since I was a Yamaha warranty servicer, and have no idea what their parts ordering is like these days. I do remember now that the platter motor is Yamaha part number VE403100(pretty darn sure, otherwise it wouldn't have popped into my brain so specifically). Also, the early Pioneer cd changers, like the PD-M6, PD-M70, with that first generation mech, used exactly the same motor with a different part number, so you may be able to get it from Pioneer if Yamaha is unhelpful. Used to order those darn motors a dozen at a time.
As for conversion to dac use, it would require a considerable technical effort. You would have to add an input receiver circuit, such as a CS8412 or CS8414, and tap it into the various clock & data lines, and then make it cooperate with the existing control & mute circuits. A daunting project for a not spectacular result. The PCM56 dac's can sound lovely, but it takes a lot of work improving the supplies & output stages to get them there.
