Classe CDP-10 - Trouble reading some CD's

I have a Classe CDP-10, which I absolutely *love*. For the past year or so some of my CD's are having trouble reading. The player will just show "-- -- --" while attempting to read a newly inserted CD, sometimes for as long as I've been patient enough to wait. Occasionally I will get a read error (can't remember the exact text).

Many of my CD's still play perfectly. And many more play eventually, but only after inserting the CD a few times.

Note that *when* the player decided to "accept" a CD, it plays perfectly. I never have any stuttering or other playback issues on any CD that it chooses to play.

In anybody's opinion, is this an issue with the CD transport, or some other component? Are there any type of cleaners out there that could fix it, or is it a mechanical issue? And if my worst fears come true (because I *really* love the CD player) and this unit is beyond repair and I need to buy another, is this one a throw-away or are there parts in here that are useful to other owning the same player (in other words could I reasonably sell this one for parts)?

Thanks for any help.
