Sony 300 disk CD changer skipping on playback

[@kevlar6328]

THANK YOU, THANK YOU, THANK YOU!!! For 15 years I've had troubles with some CD's playing the 1st song. A simple cleaning as you showed and it is working perfectly again!

[@jimmoore6033]

On 5/5/20, I followed your video instructions to repair my Sony CDP-300CX which was skipping tracks after I got it working by replacing its three belts two weeks ago. I cleaned the rod and plastic gears of old grease and regreased them with Lithium grease. No more skipping. Thanks for sharing your troubleshooting and repair video. Without your detailed and thorough video, my Sony 300 would have gone to the landfill.

[@auddoc99]

This guy has obviously been doing this for a while. As have I. Good explanation of "why", as well. I just did exactly the same thing to the same model machine. It worked the second time, as I didn't clean all of the moving surfaces as thoroughly as I should have, the first time. The old grease does turn into a sticky goo after time and collects whatever schmutz/ shyte/ dust is airborne in your house. I sometimes use very a light bike grease with good results. Or a moly grease, as he did. Sometimes the laser will also drop in output with age and on typical KSS-type Sony laser assemblies a very slight CCW turn of the laser output trimmer dials it up just a touch. This helps with burned CD copies (especially cheap-ass blanks), which have way less reflectivity, and thus less laser pickup output than commercial pressings. NOT less audio volume. Less laser output only affects playability when most discs will play and some don't, as a symptom. Good work Mr 12Volt.

I recently had SONY 200 disc CD player given to me because it was skipping & the guy was going to trash it. I used info from this video to repair it and it works great. Thank you for always having such great content.

[@MrDballmoney]

I purchased one of these at a Pawn Shop for $10 last summer. It worked but the CD would get stuck half of the time. It needs both the gear bands and CD. After 8 months of this thing sitting alone I finally fixed the bands and about to grease up the CD Rom. I have sunk in $40 total in this project but plan on selling it. Thanks for this video, you are the man!

[@astrorad2000]

Thank you for the great video. I just replaced the belts on my Sony 300 a few weeks ago, which hadn't been used for quite a few years now. started loading in cds and one started to skip on the last track yesterday. Followed your instructions and now all is well.

[@nicorosvelds3084]

I bought a 2nd hand sony mega storage 300cd for 75usd. The seller of course didn't detail the music skipping problem, he only said to clean the laser head with a special cleaning CD to avoid skipping. Well I was pretty disappointed after the first hours of listening. You're video however nailed the problem and its simple solution. It took me only 20minutes to dismantle , lubricate the rail and rebuild everything and it works 100%. Not a single skip in 50 songs from differnet cd's. Thank you !

[@45ricanman]

I was wondering what was wrong with my disk player for years now. Thank you for your insight to this matter 12 voltvids.

[@k4sar1]

Thanks! I just bought a nonworking 400-disk unit to pair with my working one, and thought that all was fine after I replaced the melted belts. But on testing it skipped on the higher tracks... guessing that all will be well after I locate some appropriate grease and finish following the procedure you kindly posted here for us. Good work!

[@user-xn1sl4sq6o]

I successfully replaced all three belts to my CDP355 following this video. Nice details. NOTE: However, If you remove the Disc optic mechanism, in your attempt to replace two belts, be sure to replace it in the exact slot at the bottom of cabinet, as indicated in this video, otherwise you will have Disc failure each time the system retrieves or replaces a disc back into its assigned slot. Also, if you remove any ribbon cable, it is most important to insert correctly or this too can lead to failure of the system. This can be very tricky and frustrating. Ribbon cables are hard to find for this unit.

All the musicbakery stuff is good. Thats why I have the library of it. When my production company was in full swing we bought a bunch of CDs from them and used it on all our commercial work.

[@andypalm7061]

Still an amazing unit. 300 cd's...and it managed them all. that's a lot of weight for a plastic gear system to push around. How cool.

[@12voltvids]

What about the 400 disk unit. That is even more weight and that one works well too.

[@stevenalpert3800]

That video is excellent, but I have a couple questions/ suggestions. 1) because a Q-Tip is too thick to fit the cotton through the bearings for cleaning, I recommend to first remove a lot of the cotton on the end, so it can fit through. 2) As an alternative to the Q-Tip you can roll up a small piece of coffee filter into a rod shape (perhaps 2-3 inches long); saturate with alcohol and pull through the bearing. 3) I would think a light white lithium grease should be a good substitute for the Molkote that is not available locally. 4) You never showed the resolution of the stuck finger holding the disk. Was that connected to the gear you cleaned? Or to the belt-drive gears for rotating the CD tray?

[@68enxy]

GREAT posting. My 200 disc Sony changer has the same problem, plus more. The cd wobbles and sometimes the changer doesn't know there a cd in the magazine.

[@CBRSTEVE08]

Thank you so much... I think this will solve my problem.. Thanks again.

[@BeachTechPC]

I was looking a 20+ year old boom box the other day with a CD player problem. When I got it apart I found that the laser gear had turned yellow and crumbled. No replacement gears to be had unless I could get someone to 3d print one for it. I noticed that the gear in this unit is also starting to turn yellow. Seems to be a real bad issue with the plastics used. I'm also seeing this problem in older video game console disc drives. Great video as always!

[@12voltvids]

The yellow color is smoke. The unit is owned by a chain smoker. Philips and Magnavox were bad for their plastic gears turning to mush.

[@ciprianwinerElectronicManiac]

My first Philips tape deck had a gear that was red colored and crumbled and then another yellow one from the autostop that also crumbled, so i had to improvise something to get it to at least play a tape. I took a small motor and atached in place of the counter via a belt to drive the take up reel. Works like a charm. Needless to say that I would never buy another Philips boombox, tape deck, cd player or anything.

[@BURTBROWN]

[@felixlutticken5694]

If your changer still doesn't work after cleaning the gears try cleaning the black disk grabber, if these get dirty they put dirt on your disc and it will skip. It took me about 2 hours to find that fault 😅 Now it works just fine 😊

[@rosemeyer1939]

[@jh-zr8uj]

Hi great video. I was able to open mine up and clean it. But didn't fix the issue. I then noticed the stem of the plastic gear that goes on the motor for the laser was cracked.

Recently got the 400 disc changer. I have the same issue with the music skipping. After inspection and greasing up a bit, I can't seem to place the box that has the laser reader on it exactly how it was before. The pin st the bottom, I can't seem to find where it goes.

[@PetersonChemistry]

What exactly am I supposed to use for the "grease"? I see molykote from Dupont but there is so many different kinds! I just need a small amount for this one job: will any silicone lubricant do it?

It actually lithium soap grease.

[@Vanabond]

Just picked up a cx450 that has been sitting for a bit, have the exact same problem. Only plays 22 seconds and then restarts. I'll tear into it tommorow and hopefully that will resolve the issue!

Great instructional video. I own a SONY HCD-HPX7 Micro system with similar issues. Can you tell me if the plastic pinwheel you removed with your needle nose pliers a sold separately, and where can we purchase them? Mine has its teeth all grinded and skips the drive back and forth. Also what kind of lubricant are you using? Molykoat # ? Help anyone please. Thank you . Fred.

[@dillwiggle2]

This was exactly the video I was looking for. What grease exactly is that you are using and who sells it ?

[@Tripredacus]

I have one of these with the same issue, I tried your fix but the problem remains. I verified the laser assembly does move into its home position if moved manually and then turned on and put in a disc. It can find the start of a track ok, even if set to another track prior to 1 (such as using 1 disc and set to shuffle). When watching the gear during play, there seems to be a slight "jog" or movement backwards after moving "forwards". I have made a video of this movement.

[@dave1ahc]

Can you use white lithium grease on that shaft for that laser mechanism?

[@mikegorsky3127]

I followed your advise and cleaned the mechanism. Now the laser head is moving smoothly and the CD plays. But there was another problem. During music playback, an interrupt occurs for 1-2 seconds. This may occur once in 10 minutes or every 2 to 3 minutes. What could be the problem? Should I replace the laser head unit or there is a problem with the power supply? Thank you!

I have a sony CDP CX 450 with a weird problem....it works fine and plays CD's with no problems until it tries to load disk 140 (1-139 OK), where it will load the disk from slot 141 (but display 140), if I request disk 141 it will load 142, then it will not load any disks until 150 where it seems OK again. It also does this at about the 230 slot position. I've tried different CDs, cleaning lenses on the sensor, checked belts on motors and under the table - all seem fine. After a reset the problem is still there. ANy ideas why this night be happening? Thankyou.

Hello this is a great instruction. Bang on.... I have a problem with my Sony CDP-CX355 and wonder if you can help., It started out as the same problem and needing the belts replaced so I did that and replaces all 3 belts. But now the carousel is stuck when I push the Disc Eject button. I notice the disc does not eject from the play before the carousel starts turning ! The mechanism to remove the disc from the optic does not operate and the plastic "V" guide remains in the "down" position. Can you help....thanks Richard

[@sharonp4744]

I have the skipping issue with my 355, so I will see if I can work it out myself. I also have a flickering of the display. Any chance that can be repaired???

[@leyland9999]

I have one of these and it still works flawlessly. It outlived the cd as a matter of fact as I stopped buying cd's. Modern cd's sound terrible, the odd exeption excluded. So all my old cd's are in this changer and they probably never come out again as long as the unit survives.

[@12voltvids]

I feel the same way about my 200 disk. Working flawlessly, has never skipped a beat, and sounds fantastic. Have it, along with an old Cassette deck and DAT player on my all tube amplifier in my living room which I put on to listen to from time to time. The sound quality of this unit is excellent. I have not bought any CDs in years, but I still enjoy the ones I have. I have well over 200 CDs though, so what I did was make compliation CDs. Ripped the tracks from all my CDs and only the tracks that I like, leaving the crap tracks. Then I burned 200 80 minute disks to the brim. Actually I think it was only about 180 or so disks and the remaining 20 were willed with CDs that every track is good, you know the samplers and stuff that record companies put out that were already compilations of great stuff. I would love to get my hands on a 300 or 400 disk, just because I love the mechanical aspect. I am still contemplating making a plexiglass cabinet for my 200, and putting it on the top shelf so the operation can be observed while it works, because it is just cool to watch. Like an old Seaburg or Wurlitzer jukebox. That is something on my bucket list, to get an old juke and restore it. My neighbour has a really nice one, and they have no kids to leave it to. (only son died of cancer several years ago) so I have been trying to buy it but so far no luck.

hey do you know if a buggered up tooth on a dvd player's laser sled gear would cause it to crap up at the same spot in a movie every time? Is there a quick way to varify this without having to sit through an entire movie before I sell a unit on craigslist? Im guilty of throwing out possibly good dvd players out of pure lazyness of needing to sit through an entire dvd just to test it to varify if it is bad or not. I had a player that appeared to freas up at the same spot in movies sometimes and sometimes play a entire movie just fine. My worry was that I'd sell it and end up hearing back from the custumor a week later saying its crapping out on them.
