Sony MEGA CD Changer CDP CX225 CX240 ect, intermittent stop fault

[@keithbeange5436]

THANK-YOU! My CX225 was randomly skipping; mostly forward and sometimes backwards. Watching your video, around the 9m20s mark, made me take a careful look at the plastic gears on the Optical Block. Without removing the block, I could see a whitish buildup on the gears. I was able to clear off all the residue using compressed Electrical Contact Cleaner gas spray, and compressed air spray. I purchased this my 3rd Sony 200 CD juke box for $33. My first unit, a Sony CX 200 purchased in July 1997, has never stopped running (over 25 years). 😁

Hello, did you put a grease in all the gears ?

[@patrickjmorgan]

These players are great for keeping your cds and dvds in one place. I had never see these till I saw you repairing one a few years back. So you’re to blame! I have the CX850. I think I paid £135 for it, remote included. Thanks Dave.

[@carlinfamily1157]

Great fix. Initially my thinking was disc wobble - however it varied across different discs. I wouldn't have guessed the door switch - last thing I would have checked. Well done!

[@12voltvids]

Was a first for me too.

[@BrianBMS]

Really learning lots from your videos. I was even able to repair my Sony CDP-CX355 following your suggestions. Thanks for sharing your knowledge. It is very much appreciated..

[@marvinwatkins8179]

My 300 Sony mega CD player used to do the same thing but now it's not doing it anymore.😂

[@MrChrisRP]

I'm currently @ 5:30 and you just said about the wobble. Yes, it is the absolute first thing I noticed when you loaded the first disc, before you even pressed play. Interesting to see what goes on from here. Cool!

[@mgrsdgfsdafsdgrsdgfsdg6980]

Thanks 12! I was looking for a band name for this new gutter punk band im producing for. They will be called, "Intermittent Stop Fault" or ISF for short.

I dunno, you seem to have a way with names... ;-D

I'm currently working on a sony cx555es 300 disc player had all kinds of problems got it all fixed except for the disc loading arm needs new springs some I'm using my cx70es for now awesome players

[@jcstudios5629]

Hello and good evening, I haven’t received the new switch yet (on back order) but CD player was working fine tonight then started the loading unloading and the CD wouldn’t spin (had the cover off). Well I removed and tested the switch with a meter and it looks to be working fine. I inspected the board then re- soldered the pins and sprayed the switch best I could. Well I put it all back and same crap popped again. One thing I noticed is I hear a particular sound every time the CD loads and spins coming from back like a higher pitch at the completion of loading and starts to spin. Sounds like something is acknowledging everything is fine to continue to play. However the sound is missing or bit different when it won’t play and it’s not a mechanical sound. The unit is the CDP-CX270. Any idea what it could be other than that switch? I cleaned the door switch too yesterday for good measure. It also has the timing belt with the inside ridges which looks ok and working but man I can not find anyone with a replacement if I needed it. Thanks.

[@neilreynolds6453]

I remember you talking about having a clear cover made to replace the factory cover so you could see how the player mechanism works. Wonder who could make one? I'm looking into possibly getting a changer like these.

The ghost in the machine like the police came out with that CD

[@centraleaves]

Have 1for sale came out of a recording studio in Toronto the basement tapes were samped on this deck work fine but it needs belts or cleaning the rails no remote

[@sickly_b]

thx for another excellent video - I have a CDP-CX235 - It powers up and the display works but none of the motors fire up - the carousel, the CD mech, the door mech - all silent. The belts seem good and these parts would not move with gentle manual encouragement. Factory reset did not lead to motion or motor noise... The only noise I got was when I manually moved the laser pickup a few cm and then hit power - the pickup then reset its position. Have you ever come across this - kind of dead, but with the lights on... Any advice greatly appreciated!

[@jcstudios5629]

I soaked that blue switch in contact cleaner. worked for a few years now back to messing up. I want to replace it but the only place i found that carry's it is ValeElectronic out of Spain and Spain is a pain only take a bank transfer for payment which are they even trust worthy? Part number for 5 pin switch is 15730021. So you know anyone else that has it? I even thought of getting the 15730031 version since looks like only the 3 pins are used anyway on the 21 version and the other 2 are more for support mounting it. I'd have to modify it to work since the round ends on the pins on 31 version. Maybe there's a way to mod the board so the wires solder directly onto the 31 round pin ends and just screw it into the chassis? Thoughts?

[@12voltvids]

Did you try digikey or mouser?

[@jcstudios5629]

@@12voltvids I did a complete google search and ended up ordering one from PartsWarehouse but will have to toss the board the switch currently is mounted to and modify and solder the cable wire directly to the switch. I only hope it reaches because they left no service loop😂 otherwise more work but I’ll get replaced. They only other place that had the 5 pin switch other then located in Spain was France and they only ship to a handful of countries not including the US.

[@jcstudios5629]

​@@12voltvids Update..when a CD loads, the laser I assume tries to read it and if all goes as plan, it omits a sound which is what I was hearing. What’s happening is it’s not reading it correctly a lot of times so the disk sits there for a few moments then gets rejected and reinserted. This keeps do it over and over and some times moves on to the next CD. When the last one loaded, I tapped around with a chop stick and some how got it to start spinning. There’s what looks like a small screw driver slot cap adj. on the laser. Maybe it’s just needs a tweak to fix it? I don’t want to just start adj. it not knowing how sensitive it is or not and add a problem. Are you familiar with that adj.?

[@johncwik7537]

I have done all the maintenance I can think of: 3 belts, cleaning, deoxit and grease. CD gizmo in the back will not activate at all, even during system start up. Disc rotates to the appropriate number but arm does not pick up/load Cd. What am I missing?! Help!!

[@RonRJr85]

I know this is an old video, just picked one up but the door won't stay shut. Any chance there is a video or photo of what the door lock should look like or how it operates?

[@Shadepariah]

I got an old Technics PG-300 where the clamp rubber pad disintegrated and started leave oily residue on CDs and causing some of them to jam in the machine. I got a rubber pad (for furniture) in a roll off amazon and spent HOURS getting the pad shaved down to the exact width and thickness to properly clamp the disc without it clapping into the tray. All that and now I realize the real problem is the motor oil is starting to seize up in the thing. It won't play some discs at first, but if you get one playing for like ... 15 minutes, it warms up and plays just about anything after 30 minutes. I'll just use it till the motor finally gives out I guess...

[@12voltvids]

A drop of light oil on the spindle motor shaft goes a long way.

[@darinb.3273]

Indeed tiny dab of oil on the end of a tooth pick will lube the motor shaft and bearing without being way too much oil. As Dave ALWAYS says too much is way worse than not enough.

[@darinb.3273]

@@12voltvids I am watching this video again LOL. I wanted to comment about what you said about a vinyl record playing with that much warp. Perhaps I could be wrong with what I'm going to respond with, CDs spin as you recall 500 RPM at the start and slows to 200 RPM at the out most portion of the CD. A turntable spins a max of only 78 RPM. A slight warp as was happening with the CD (the 1st one) I personally don't think would be an issue at only 33 1/3 RPM. I have an LP that wasn't stored properly and it developed a fairly severe rise and fall basically a hump and it causes it to be unplayable because of the rapid rise and fall because of the hump. I may try placing a heavy book on the hump and see if it works well enough to record it. I'm aware of the more expensive and extreme way using a product like "Vinyl Flat" in which the product is heated at a relatively low temperature for like 4 or 5 hours in an oven, I wouldn't spend the money on such a device (crazy expensive for what it is) $159.95 US. Thick plate glass would be far less expensive with cardboard or poster board between the glass and record on each side place heavy book(s) on the glass and heat the whole thing if desired. It would work without heat it just takes A LOT longer maybe a few months to a couple of years. Anyway back to warped CDs, the machines are pretty robust as far as playing discs like the 1st one (although there is a higher chance of errors due to the massive movement required by the servo lens to maintain focus. I've done experiments by placing a tiny piece of paper on the edge of the spindle motor table simulating a warped disc. Once with just the piece flat, then folded in half and then an additional fold making it 3 layers thick. With the three layers it could still play the inner portion but as it progressed it would begin failing to maintain focus, because it exceeded the travel of the servo lens. That bit of wable is mild compared to what a tiny piece of paper causes as I said three layers caused problems where one or two didn't at all. This was regular typing/copy paper thickness I used. I did this experiment to find the limitations of the CD player I was using of course each brand will vary from one to another, that's fun for me to experiment in that way.

[@stevelibby6852]

I've got a unit that works GREAT but the carousel makes more sound that should to be normal. I figure it needs some grease--does that require a great deal of disassembly?

[@zx8401ztv]

Switches are a pain, but optical sensors can go silly also. If muck builds up on either then madness can happen :-D The tiny front panel function switches often show odd resistances, they should be sealed but they still go bad. Maybe a hall effect device and magnet could be more reliable, perhaps lol.

[@jimweaver8297]

My 225 is out of alignment and most of the time can not get the disc centered… how can I find the right adjustment ( which screw moves it up or down in or out?

[@austink514]

I have a CX210. I am having a problem with the CD not being perfectly aligned with the clamp. It is USUALLY close enough that it audibly "pops" into place and plays fine. (guessing this is caused by the assembly hitting the edge of the hole and popping into place.) Every 20-30 discs the alignment will be off enough that it clamps but the disc isn't centered and can't be read, the CD then gets chucked into the void. My best guess is the chucker mechanism isn't stopping at the right spot. Could one a dirty gear or the blue switch be the culprit? Have you ever seen an issue like this?

[@jimweaver8297]

did you get an answer?

I have one of these too, it keeps switching back to standby while it's being used. I keep meaning to pull it apart and check the capacitors in the power supply. I was hoping that might have been what's wrong with this one so I could watch you haha

[@enricoself2256]

I think i have been lucky: I have serviced many Sony CD traverse and so far no cracked sledge motor gear. The plastic is slightly different though, it's more yellowish and opaque, maybe a different type which does not shrink over time. I have seen many cracks in the plastic strip covering the left rail where the optical pickup slides onto, but that plastic is more whitish and translucent (i guess it's nylon which is quite slippery even without grease). Anyway it's the usual the problem of plastic moulded onto metal: unless the plastic is super stable, over time it will crack; and unfortunately, Japanese loved to sandwich plastic and metal...

[@playstation2bigs]

Does putting grease in all gears recommended?

[@enricoself2256]

@@playstation2bigs Sony used to add grease only on the rack and pinion moving the pick-up sledge. The sledge itself has to move also with minimal rotation of the motor and sometime grease can be a bit sticky. If not strictly needed (noisy gears) I would not add grease on all gears

Can you put 200 disks in a mag player? No! Mag players have their own issues and lots more. Plastic pieces to break and even more sensors and switches. Nope mag players are crap. Only good for car changers.

[@nickwallette6201]

@@12voltvids I gotta agree. My first CD changer was a 6-disk magazine plus 1-disk drawer. I put 6 disks in it, and they almost never got changed. I fed the drawer instead. I felt superior, because I was a teenager with a fancy Kenwood HiFi stack, and all those peasants with their mini-system 3-disk drawer changes had less than half the capacity. But I bet they used it more.

[@12voltvids]

@@nickwallette6201 well picture this, two of these changer connected one is the master the second as the slave, 200 discs in each with Crossfade set between the two changers so as one song is ending the second song is starting crossfading then the changer that just finished cues up another disc ready to go so that when changer two is finished a cross fades back to changer number one. No breaking the music it just goes on forever. Now that's a cool setup 400 discs but I can do one better because Sony made 400 disc versions of these players and you could stack three of them. How does 1200 discs sound?
