- In this final part two video concerning the Rotel RCD-955AX compact disk player, I resolve the seized / stuck tray issue and go over my cleaning and re-lubrication method employed on this unit, as well as touch on lens cleaning of the optical pickup etc.

Big thanks, man! 👍
My pleasure 🙂
enjoyed this 2 part series. currently troubleshooting a rcd-965bx that makes a swishing/chirping noise during playback.
Thank You for chiming in, hope all is well. Some times that type of problem can be on account of a few different contributors, which can make diagnosing the problem more difficult at times. For example, could it be an issue originating in the electronics / i.e. a failing / failed component/s that may be disrupting some normal playback control functions? A definite possibility, until ruled out through some quick signal analysis and spot checking of voltages (etc.) along the "signal pathways" and all supporting circuitry that may be in question during a good ole fashioned diagnostic session. So, there's that part of the equation, when dealing with the electronics, and whether or not a person is able / willing to dive in to that world of work? There's also the obvious mechanical part of the equation, which typically isn't too big of a problem to contend with, and I first follow a "CLA" approach, "Cleaning, Lubrication and Adjustment". As mentioned, things need to work / move fluidly along their path of design, without interference, along a track / rail / pivot point etc., of which needs to happen in a fairly tight and fairly precise manner. If there's no useful data available about the mechanism You're working on (which will often be the case), then You'll have to study the mechanism/s, to familiarize Yourself with their intended operation, then You could troubleshoot from there, looking for common / expected problems involving "moving parts". So, again, from the electromechanical list of things that might be be the problem, I'd of course start with the obvious stuff. Make sure the lens element of the optical pickup (laser) is clean, free of haze / fogging/Heavy scratches/ nicotine/tar accumulation. Of course, that's a common cause of "read issues" (dirty lens) which could be causing Your problem etc. Otherwise, if You go into the electronics / electrical adjustment phase, it would be a good idea to track down a service manual if possible. As You can see, this can get lengthy because of the various possibilities. So, start with the preliminary stuff and build Your "file" as You move deeper through the layers. In closing, once You have a good solid grasp of How these machines function, they're all pretty much the same (in principal), nonetheless, I'm going to cut this here, my best to You, I'm sure You'll get it worked out, let me know.

Thanks for the reply! I've had the unit apart 3 times now trying to figure out the noise which can be heard across the room during quiet passages. I cleaned and lubed the tray mechanism, gently cleaned the laser with isopropanol 99%. I also made sure there was no interference of the disc as it rotated or foreign object within the mechanism. The chirping persists. I am going to bring it to my local electronics repair center who are authorized warranty repair for Rotel among other brands. There is a $40 diagnostic fee and then about a 30 day turnaround for the repair. I hope it can be repaired fairly easily. As old as it is, I still find it to be a very musical player worth fixing. I will report back on their findings. I have read of others having the same issue on the audio forums. Thanks again.
@@deathb4digital That's good You're able to find someone near You who can look into it in more detail. At least You ruled out (to some degree) any obvious mechanical issues etc. My best To You, hope it gets resolved. 🙂
Poor tracking on this mech is often the bearing in the top clamp. Release the springs, take the top arm off and in a clean area lever off the white bearing housing careful ball bearing may fall out. Clean bearing and cup, lube bearing top and bottom with best grease. If it's worn an indentation(s) in the arm a good indication of use, smooth it out with sandpaper or cover with teflon sheet. Blue tac on the crystal improves soundstage. Replace c160, c301 with polymer.
Very informative two videos. I just picked up the same cd player. So far, everything seems to function well, and it sounds good - except the door faceplate has the same problem as the one in your video. Were you able to repair it as you planned, or did you end up using a different method? Thanks.
Hello there, I did a little video on that but I titled it in a way that isn't obvious it's related to those other two Rotel videos, or else you would have found it, why make things easy right? ;-) Anyway, below is the link, you may want to skip through some of the chit chat, or not, my best to you :-)

Thanks for responding. Very helpful - and I enjoyed the chit-chat. It looks like it will be an exercise in patience. Not a bad thing at all. Take care!
