Sony CMT EX1 CD Stereo System Repair

[@keithsottung7231]

Yo!! From Philly. Thank you!! I have CMT-EX100. Slightly different. We just pulled the rubber band and ordered a new one. It won't be here until Feb 2 2023. Can't wait!!! The CD ejector hasn't worked for 5 years now But I couldn't bring myself to get rid of it. Fingers crossed. I'll post back after we install the ban.

[@ChonkTek]

Did it work?

[@henrybutchy3242]

The hype is real. This little unit is an engineering serendipity. It works well beyond any expectations. As 12volt says late in this video: "I'm totally impressed. Wow." Yep. Second that.

[@indira8392]

Thank u so much!!! I had the same problem with mine. I got it from ebay without knowing it wouldn’t work. Your video was very helpful. Now i fixed my sony cmt ex1 and can finally hear my CDs!!

[@dlarge6502]

"Gives you something to watch" Funny, I never realised but when I was a kid playing tapes I would stare at the spools turning. When I play a record I watch the stylus slowly track and move about, very relaxing that. But with CD I always had the disc obscured, hidden in the player. Same with minidisc. Now I see this, I may grab one if I see one, even though CD's spin so fast as to make it a blur. I may have fun trying to print CD labels with patterns on that may work, or perhaps under a strobe light! Cant do that with streaming ;)

[@12voltvids]

Why do you think people keep real to real machines? I've got nothing to do with the sound it's all got to do with the aesthetics of watching the reels turn

[@StandardUserFromEarth]

I found that taking off the amp motherboard and it's stuff underneath it, (the one attacted to the back pannel) made it easier and less fussy to work the belt through the gears since it opens up that part of the unit to get your hands and tools in. The components are attached to multiple cables so you just have to unscrew all the screws on the back and lift and set it to the side, easy to silde back on, without the need to worry about soddering or messing with the electrical parts.

[@OldSonyMan]

Thank you for this video, I bought this unit about 15 years ago (before I got into repairing things) it wouldn't eject the discs either and I soon gave up ! Now I have a good idea about how to 'fix it' I'll order a belt and 'have a go' Cheers ! ! !

[@stevenrodgers7051]

just ordered a belt too. be good to finally get it fixed

[@OldSonyMan]

Update : my machine is not an EX1 ! It's an EX100, very similar (identical mech). I got a replacement belt and discovered that to fit the new belt it was only necessary to remove another 3 screws and the amplifier module (just behind the door motor) just swings out of the way ! Still have to feed the belt through the gears but it's much much easier. The biggest problem with the EX-100 is refiting the 'all in one' housing because of the 6 feet which protrude underneath the unit. After a lot of experimenting I found that locating the glass panel was the most important thing ! Good luck everyone !

[@SergZak2023]

Very nice little unit…free makes it even better! Great score, Dave.👍

[@amogussus2744]

I just got one of these while dumpster diving! Its looks so good.

You didn’t try MP.3 s ?

[@Jammerk40]

I like that CD you have playing! Good music!

[@life5161]

Not nit picking, ok maybe a little, but Tip from a detailer: Cleaning with a clean well shaken out microfiber will be far more effective next time. Paper towels leave too much lint and streaks. I mean long as your happy with it fine, but thought I'd mention it incase you weren't. Your repair videos are extremely entertaining and educational.

[@12voltvids]

Doesn't matter how clean you make it, within 24 hours dust will be all over it again.

[@tacofortgens3471]

Sounds very nice indeed, My dad had a JVC with glass cd lid on top. Was a 10 year anniversary edition

[@12voltvids]

The price was definitely right.

[@hoffmannolsen]

This reminds me of the first Sony CD player prototype, which I really love, but wasn’t ever in production.

Thanks 12! I have a different model I currently use and bought a replacement belt when mine goes bad. I had no idea how it operated until now.

[@richardsmith2721]

Great little vintage system!

[@tall_dude1233]

And it's not even that vintage - probably 18 years old at most! I'd call vintage at least 1970s and older.

[@oreothehamster31309]

thank you for this, i've had mine for years and i've been having the same issue with the cd not ejecting the last few months

[@allmyloversdie]

Do you know if i can replace or fix the screen at all? The screen on mine burned out and is super hard to see

[@aarongunter5582]

You had me rolling over here when you started snacking in the hell out of it lol 😂 😂😂😂😂

I bought one of these at circuit city in I think 2001. Just bought a broken one to fix because Im collecting old radios now. Your video looks like the solution. Thanks. But 1 quick question. Where can i buy the rubber band cheapest and fastest and how do i get a matching size?

[@12voltvids]

Have no idea where to buy belts.

[@jimbergen5232]

After finagling the belt, all seemed fine: " But wait, there's more " - " 16 tons what do you get.. " Oh, just a " Cat Scratch Fever " disk.

[@wal]

Great video! I have one of these with the same issue, so now just to sort out that belt and replace it 👌

[@johnsampson1096]

Nice score, Dave. I wonder if writing on a CD causes malfunctions to the laser pickup? Maybe the opacity of the disc is also a factor along with dye coloring..........

[@darinb.3273]

Hello John, typically felt tip to pens won't affect the contents PROVIDED the chemicals used in the pen don't break down the acrylic coating just under the label. NEVER use a ball point pen to write on a CD, it is very likely the ball point pen wouldn't work anyway. I seem to remember felt tip pens that were especially made to write on CD-Rs that weren't supposed to mess with the acrylic coating not sure if it was just hype or not. I've used Sharpie on many CD-Rs and no issues at all.

[@OHYEAAHH203]

Awesome video! I just picked one up at a yard sale for $25. In decent condition but missing the two back feet on each speaker and the back removable panel has broken tabs. I have a question about the glass front sir. One of the sides has come undone from the silver post it sits on. What type of adhesive would you recommend to reattach it? I don’t want it to look like I just put some pile of glue on the glass. Any help is greatly appreciated. Thanks!

[@ChonkTek]

I've got one with a soft touch style eject button on the top of the unit, and it doesn't make any motor noise when I touch it. Yet the display does indicate "OPEN".

[@DeezyzWorld]

Do you know what wires it uses to connect to the speakers? Mine didn’t come with any

[@blackenedmagic888]

Quick question ... Where do get your replacement belts for stereos, VCRs, etc.? Do you have a local source or do you get them online? The reason I'm asking is I may have to get replacement belts for a ghetto-blaster and, to the best of my knowledge, the nearest place I might be able to get them is Toronto (about two hours west of where I live). Any suggestions would be appreciated!

[@12voltvids]

I have bought some online. There is a local source but i need to know the exact size which usually I don't have

[@tall_dude1233]

Very well featured unit. Coax FM input and optical audio!

[@peteg24]

Does that little belt control the laser housing piece and its movement? When you press the eject button it looks like the laser housing unit moves back so that the clear CD tray can move upwards so you can load a disk in. Is that motion controlled by the belt you replaced? I just found an EX-200 and the CD tray tried to move up but it looks like it’s blocked because the laser housing piece does not move backwards allowing the clear tray to move upwards.

[@Jammerk40]

Great finds Dave! Hey clean those woofers up they are dusty!

[@zx8401ztv]

A very unusual design and neat. If it still hangs up, its worth pulling apart to clean the mechanism. I first thought the power supply had a dry joint, as it just stopped dead.

[@KarenCamacho-bw8ne]

Hi. I was having the same issue with mine and came across this gem of a video. How do I go about buying the replacement for the bottom speaker. Any help would be appreciated.

[@OHYEAAHH203]

Are you missing feet from the bottom too? Did you find some replacements? I’m looking too. Thanks

[@erinmulroy377]

Hi if I don’t have a belt will a rubber band work? Thanks

[@12voltvids]

Maybe for few days till it breaks.

[@Synthematix]

Try and get hold of a Sony RB-1, had mine over 20 years from new it hasn’t missed a beat, brill little stereo.

[@Synthematix]

Sorry i meant Sony CMT RB-5

[@BannedPlushie]

Mine has this issue of it playing some discs and not playing some at all possible laser issue? Maybe some isopropyl alcohol on the laser to clean it? I’m not really sure what to do.

[@12voltvids]

Are these stamped or burned discs?

[@BannedPlushie]

@@12voltvids stamped most likely none of my cds are burned

[@12voltvids]

@@BannedPlushie laser or spindle motor must likely. Bearings wear out and cause vibrations that make reading the disk difficult as it causes excessive jitter.

[@BannedPlushie]

@@12voltvids hmmmm ok ok thanks ima try and diagnose is some time soon it does have an issue of raising the disc grabber thing and then when I tap on it it goes up possible motor then

How do you fix a display that won't light up (work) but you still get audio and power on this sony model?

I got one of these to,also picked up for free with a bunch of cd’s👍

Ya if i saw that for free, i would pick it up too. Hope you all are having a good day. I grew up with a small black and white tv, that size. Really liked it because it had head phones, and it was my own small tv.

@@12voltvids kind of nice to be alive. But its hard knowing people the passed away would of done better. Good luck with your channel and fixing stuff. Seems like theres a whole process to learn, Seems like the cd lens is jamming.

[@jamesbaker429]

One of the better units of its type , better display and two way speakers ,it may be worth a listen via bigger hi-fi speakers ,you might be surprised more as often the limiting sound factor is the speakers,the box and two speakers taking up the budget but of low quality also a swap to thicker speaker cable may improve the sound,a good looking unit in as new condition again.

[@12voltvids]

@@jamesbaker429 that other flat system that has the CD and md recorder also has fantastic sound. I have too many stereos around here. At least six maybe more. My living room I've got three alone.

[@coolhandluke-123]

Is there any danger of seeing the laser before, during or after CD playback? Was thinking of getting one of these but always paranoid that I could damage my eyes if the laser was even slightly visible? I assume the laser doesn’t fire up until the disc is in the front loader and can’t penetrate the CD layers - so no risk whatsoever I guess?

[@12voltvids]

You do notice that opaque strip on the glass right. That's to stop laser from shining through the glass.

[@Watcher3223]

I wouldn't worry about the laser, especially when using the unit normally. One, when playing a CD, the beam is primarily reflected back into the optical pickup by the reflective substrate of the disc. Second, without the CD in the way, the beam is highly diffused from a very short distance past the objective lens. Third, the beam is very low power; only enough to read a CD. Fourth, as 12voltvids points out, the laser is blocked by an opaque label affixed to the glass over the traverse, which bears the words "VERTICAL DISC LOADING MECHANISM."

[@12voltvids]

@@Watcher3223 it's the nany state. Everyone is worried about everything.

[@EastAngliaUK]

I bought a cheap JVC UX-DAB 11 Home Audio System for only £3 the other day it goes perfect the Sony CMT-CPX11 micro hi-fi system is better quality though but my other HK980 and KEF Q1 set up for series sound.

[@ceilingfanmusic6597]

it could be falling victim to the capasitor pleuge. i know equipment from the mid 90s to the late 2000s were affected by the capasitor pleuge. even well knowen brands like Sony suffered from it. equipment would act eratic and have all kinds of wired issues from it. im not saying evrey issue is a capacitor but with things from the capasitor pleuge arra i would definitely check for leaky or high esr (dried out) caps also a side note. some cd players from the 90s an even erlie 2k didnt like playing cds with more then 16 tracks. ive come across afew of these. but the sony in the vid seems happy about doing so with a cd thats not all scuffed up

[@12voltvids]

Scratched disks are tough to play. That disk skips on other players as well.

[@metalfatigue]

For a moment, I thought there was something wrong with the player. Until I saw the condition of the disc you were trying to play.

[@chezsnailez]

See what You're made Of by Rick Hart and The Blue Horse!

[@12voltvids]

No, Rick hart stole the music bed from musicbakery. All the music i use is royalty free from musicbakery.com. The composer is Jack waldenmaier. Rick hart is a session musician and played harmonica on some of the tracks. It did some vocals using the music bed from some of the tracks which is legal however he can not copyright it because the license is very specific. The royalty free license gives the user non exclusive rights to use the licensed content. You however can not sell the music in whole or in part. I can sell videos where i use it because I have a license to use it in my videos. Rick hart can sing along but he can not make copyright claims against anyone else that uses it because he doesn't own the music. Jack waldenmaier does. If i used his vocal track he could claim that but not the base tracks as nobody is granted non exclusive use rights. Understand?
