It sounds to me as if the laser is reading the disc at the same spot as the cd spins. It is a regular heartbeat-like skip or sound outage, that I think is related to a possible alignment problem or a dirty laser. Is it worth fixing or should I buy another carousel unit? I really loved this 300 cd changer when it was working well but If I take it in, I'm afraid I'd have to re program each cd again. That's a lot of work. Is it possible for me to simply open up the case and vacuum out the accumulated dust? Or should I just bite the bullet and take out all the cd's and take it to a professional. I don't know of a good one in Santa Fe, New Mexico. Any suggestions?

Hi There are many things that can cause your problem, I can tell you the most likely ones, but I recommend you don't take the unit apart, as the mech. in a 300 disk changer is complicated & delicate, and you may just cost yourself alot more money than getting it repaired. The symptoms you sescribe can be caused by failing laser pickup, dirty laser lense (especially if you've done home renvations with drywall), split drive gear that moves the laser on the sled rails, or even a hair or piece of dirt in the gear teeth of that same gear. The unit will play fine, until it hits the tooth where the debris are, then it skips, or jumps back a bit and starts again until it hits the same spot. Also..badly scratched or finger printed disks will cause that, but that is the first thing most people check. I wish it was something you could repair yourself, but my best advise is to take it to a reputable repair shop, and hope it is not a bad laser, as that is a fairly expensive repair. Hope this helps, Good Luck!

I got a free one of these from my work...well that is because it was having the same problem and they didn't want to mess with it haha. Sooo...I brought it home..thinking i could just buy a cd cleaner kit and clean the dirty lens..which is what normally causes these problems. To my dismay this didn't work (later found that the lens is a good half inch away from the disc)..so i decided to open the bad boy up (hey I got it for free...no harm crackin it open :-) ) After hitting the lens with a can of air..I tried again...no go. And just so you all know...this player runs vertically..not horizontally. I want to know how does the player read? the lens in stationary. All other players i have seen the lens moves up and down. I'm thinking it might have something to do with that. I gave up on cleaning it and started doing some searches..this was the only forum that was somewhat helpful. I agree with Silverscreen. When i watch the cd's playing the disc wobbles SLIGHTLY up and down. I think the rear stand-alone wheel is a bit too loose. ..The amount it wobbles is hardly noticed but is the only thing i see out of the ordinary.

Pretty much the only thing you can try at home is cleaning the laser lens, if the cleaner works then remember to use it now and again.
If the CD lens cleaner does not work the take it to the nearest sony tech/dealer for repair. Multi CD systems are very complicated and need specialist attention.
Hope this helps
Thanks for using FixYa

Hello,
how long have you been using this player? I suspect the laser (lens) of the player. I think the laser (lens) is weak that's why it is refusing to play any more CD....
Get a lens cleaner, use it to clean the lens. If that doesn't solve the problem, get a screw driver, open the player's cover so that you can gain access to the lens, use a cotton board to clean the surface of the lens. This should clean dust or dirt that might be on the lens. You can add very little liquid to the cotton board like mentholated spirit and dry the lens with another cotton board that has not liquid on it.
If non of the above solves the problem, then it means the lens is weak beyond cleaning. Know that you need to replace the laser to a brand new one.
To replace the lens, remove the bad laser, use it as a sample to get exactly the same type and do the replacement. Note that replacing a laser (lens) needs a professional touch, so if you cannot replace the laser, get it to a repairman to fix it for you.
Once this us done, your player will play all CD's again without any problems.
I hope you understand the above.
Regards.
