That was so awesome, I particularly liked your approach with one item and then check if repair was concluded ,that’s shows a lot of devotion to doing it right and though. You must sleep very well knowing you do your best to achieve 100% repaired . Thanks you made my day.
Just bought a dead CDP35 for £5 - bridged the two fuses with wire and voila - we have power. Many thanks and the step by step detective work was very informative.
Amazing board construction, flipped inside out, a joy to test and diagnose. All regulators have their own anchored heat sink, components look top notch. Much respect to SONY's build quality.
The whole review you do at the end to show off the features is great and illustrates how some of the older players area so much nicer than ones available today. I have a Sony 5 disc player that has all of the usual array of buttons for FFW/RW, skip, peak locate and more that just isn't available on new players today.
It all comes down to price. People didn't want to pay extra for the index buttons to search the sub-index because very few CDs actually used sub-index. I think the only discs that I own that use the sub index with some of the fresh air desks by Mannheim steamroller. They may have been some classical discs as well but I wasn't a big collector of classical. I was more limited to rock jazz fusion new age and the Manheim steamroller series which I have all five. The buying public wanted cheaper devices and if the manufacturers could shave a penny or two off the cost of each unit by eliminating those buttons for index they were going to do it because it was a little used feature some left the buttons on the remote for a period of time but even those became very basic. It's all about cost and the big problem is as soon as one company offers a cheaper less feature laden version everybody else jumps on the same bandwagon because they're all chasing the same customers and the majority of customers aren't looking for those features they're looking for price.
Just found the exact same CD player for 10 bucks at Goodwill and it had almost the exact same issues, fixed it up in 1h, works great now. Initially just shunted the little breakers... Thanks for the video...
This is one of the fastest Sony cd players I have ever seen. I love the design. The front panel is made of plastic but looks really high-grade.I was lucky to find one CDP-55 without any electrical problems. My unit only needed a new belt for the loading mechanism that requires an extra grip after closing the tray to move the clamp down. I stretched the spring on the downside of the tray a little bit to reduce the resistance. It's a lot easier to change the belt if you remove the front panel to take the tray out.
Yes, I did. Ive never heard of an ICP! And you taught me how to use my CDP-761E that I bought this week complete with a Yamaha AX-392 and a pair of Whardale Diamond seekers for...£32!
It is a very fast playing unit, I especially like how the disk stops so quickly before ejection. I've seen many disks ruined as they keep spinning. Another feature that I have only come across on Technics CD players is a scan facility that finds the loudest section of the disk so you can set recording levels! Great vid as always!
No thumbs down for using soldier wick as after I seen you using it I found it great and you can trace the fault very quickly so great work. I have to give you 1p out of 10 as you do excellent work.

I have no issue with solder wick at all, it’s fine if you know how to use it. You’ll get the best out of it if you wet the joint with a little bit of flux first. I much prefer it to a spring loaded solder sucker! It’s pretty vital for SMD rework too!
This series of Sony CD players had an issue that the spring on the back of the loading tray mechanism hardens over time. If no CD is inserted for some time. the spring will harden. After the tray closes, the disk clamp won't close completely, or lock up. The fix is to remove the spring and cycle it, stretch it out so it regains its springiness. You remove this particular spring at 25:42.
That's right. The disk chucking spring. They were actually too tight at the factory. If you noticed this one had already been stretched out slightly. Sony actually had a replacement spring that was not as tight as the original, but everyone just pinched it slightly with the side cutters to loosen it up a bit
Thanks, damn ICPs - got to load them in my brain, in case I come across equipment that uses them. The older units have all the features on front panel and are very intuitive to use. Indexing - can't find it on newer CD players, I often use Stereophile Test CD with tests tones and they are all indexed, making the use of this CD very user unfriendly w/o Indexing option build into CD player.

That CD player is fast because it use a KSS-121 pickup! Used on high end Sony CD player and the others as "BU-1." The only difference is the sleding operation (gear movement vs electromagnetic movement)
I have seen the cdp291 CD player. A common one with the kss240 pickup, and single cd. An early 90s player. Not very much inside of it. Tiny power board, single cd deck thing, and a board for the front controls. The CD player uses a tiny circuit board mounted underneath it.
Do you by any chance repair old PC CDROM players from the early to mid 90's? I have a stack of 2X speed CR-563-B CDROM's manufactured by Matushitia-Kotobuki Electronics Industries LTD of Japan that either no longer spin the disk or if it does it no longer can read the disk. Unfortunately this is the only CDROM drive that I know of that works with the Creative Labs sound cards such as the Sound Blaster Pro2 and Sound Blaster 16 sound cards that still had the Creative marked 40 pin CDROM IDE interface. I can provide you with the needed PC supporting components (Fully working Intel based 386-33 computer) including a working drive to use as test bed for testing these drives as you diagnose and repair them.
Right, it was a great feature, and underused. One album that they should have used it on, but didn't was Jean Michel Jarre, Oxygen, Equanox and Magnetic Fields. Especially oxygen. Nothing more annoying that having that CD in the jukebox, set in random mode and it crashes in on a track half way through, or cuts off half way through because the disk engineer formatted as tracks (with no space between) as opposed to using the index, so when a player is set to random it plays the entire track as it was supposed to be heard on the album a full side at a time. I ended up ripping the tracks, and stitching them together to make side 1 and side 2 play out as a single track.
It was 15 degrees here in Ipswich UK. As you say, not bad for November, but it was VERY windy here. By the way, what's the big deal with using de-solder braid? Seems absolutely fine to me.
About the solder wick..I am very young in the game, but not wicking can lead to pulled traces if you don't wick it after the solder sucker..That board was well marked for the test points, that's nice! Pretty neat old cd player, I wonder what DA converter was used?
Jason Brindamour The da on this one was nothing special. Sony made their own. Some of the high end es players like the 555 or 777 used burr brown and those were really smooth converted. I have a 555es and it sounds so good.
Electone_Guy Well we set a record for Nov 22. Got up to 16.8C. Almost beach weather. As I said no jacket required working outside. Even today is pretty warm. Double digits by 11 am.
Any particular reason why you don't use a desoldering pump? I only tend to use copper braid, wet with some flux, when I have a very stubborn through hole.
エステティック Funk I don't have one and can't justify buying one. I used to have one and it was always clogging up and the boss refused to buy new tips ect. So I went back to solder braid. Works for me. If I was doing this for a living then perhaps but then I would have an air station as well but I retired from electronic repair back in 2003. For the small number of components I need to unfolded the braid works fine
12voltvids That's a more than fair explanation. Thank you for taking the time to answer my question. I was asking more out of curiosity than anything else.
@@AestheticFunk SOME USE A PUMP...........I DO............I SUPPOSE WHATEVER WORKS FOR THE EE GUY WHO S DOING THE REPAIR..............OLD SCHOOL GUYS TEND TO USE A SILVER BRAID
you have to take some "Molycote G-33" for metal on metal gears/sliders. (orG-68" if you want plastic or plastic on metal). There is no reasonale alternative to go unmarked oils and greases which lack a clear specification. This may work for some months or even years. but if you want to preserve stuff, don't cheap out on the grease, since a pot will last (nearly) forever.
I really enjoyed how you shared your servicing of this CD player. I learned a lot. You're an excellent instructor. Being that this is an older CD player, how long do you think the optical pickup will last? Is there any way to gauge how long an optical pickup will last? Thanks, Tom
THOMMGB optical pickups can last a long time. Most failures are caused by environmental conditions. Smoke, humidity ect. Clouds the lens and internal optics. The spindle motor is more likely to fail with high usage.
sony stupidly used similar IC fuses in their PVM 40 series monitor power supplies, blows if its been off for long enough that the caps need to reform, i replace them with something that is not as fast blowing because its an unavailable part and because they like to blow open without a fault, i like to use littelfuse 395 series fast acting fuses for the PVMs
I just bought one of these today in Toronto area mint in original box..or $30.not a scratch anywhere... plaus welll but needs a tray belt... any idea where to get a remote for it ?
Not anymore. There used to be a place on Toronto that had all the remotes and accessories. I forget the name but I'm sure they are out of business. Try Amazon.
Do you use/have a proper set of J.I.S. cross point screwdrivers? Though they look like standard head Phillips ones, the spec/profile is slightly different and can cam out the heads. There is a "dot" on these screw heads which almost all Japanese/Asia products use.
Yes I do know the difference. I do have a real Japanese cross point screwdriver. Actually I have 2. That little blue #0 that I use for cameras and walkman is a Japanese cross point. I also have a #1 cross point with a wood handle. These were very popular on Sony beta VCR. Since it is a #1 I don't use it very often as most screws are #2, and I just have a philips which works fine for the few jobs I do.
The Phillips CD900 had index search as well as track search, will that machine play the tracks that are hidden in the pre-gap, Tony Braxton CD Album Secrets had two indexes on the last track which was actually the title track index_1 is the secret part and index_2 is the normal part of the track for players that didn't have the index feature.
DAVID GREGORY KERR Never heard of a player that can't play a disk. What most hidden cd did was record the bonus track at the end of the last track and put 2 minutes of silence between. A cd player with index would play it immediately and for cheap ones without index they had to listen to 2 minutes of silence then the bonus track played.
I Ordered A 5 Disc Boxset Of Jerrylee Lewis & Windows Media Player Wont Except It. Could It Be The Files On The CD Are Too Big? Cause I Had That Trouble With A Burle Ives CD.
Spot on, it seems to be in great condition, the lazer must be A1, like a new one. What's the hatred for solder wick?, sometimes it's far better than a desolder sucker. I use both, i find solder wick ideal for clearing solder bridges on smd chips, created by me LOL :-D.
Though the sucker is very useful it sometimes it will rip of the pads with it, especially on single sided boards, solder wick is much more delicate, but it can also be a nightmare on double sided boards.
tOnito, Yes you need to assess the pcb before deciding, i'm used to using the sucker for through hole parts, if kept clean the sucker works quite well :-). Also you have to use speed to apply the pump really fast so the solder has no time to cool, if you don't have fast reflexes use wick :-).
Both have their place, the skill is knowing which to use and where. Loving the CDP-55, Dave - a player way before its time, for sure. The sound quality was remarkable for its price point too. BTW - I owe you yet another thank you; watching your videos has woken my inner-tinkerer, and I have recently resurrected two fluid damaged laptops, repaired a couple of printers, and have a cassette player in hand at the moment. It appears that those of us willing and able to look at stuff are something of a dying breed here in the UK too - - I am never going to make a living at it nowadays, but maybe a wee bit of pin money and the satisfaction of saving stuff from the dump. So, thank you - I had given up on our trade 20 years ago, and here I am pottering about once again.....
23:38 There shouldn't be a pause between tracks - at least on a good CD player. A Red Book audio CD is basically a stream of PCM audio samples (with some extra data sprinkled in for error correction and the subcode, which basically stores the timecode of the CD, there are 75 timecode "markers" per second). There's no "gap" in audio between tracks. ' All a CD player would need to do if you reach the end of track 1 and start track 2 would be just to update the display to say it's playing track 2. it's not like a collection of MP3 files where your MP3 player has to stop playing the track, open the new track, load it into memory, and etc. It's a continuous stream of audio data.
It all depends on how the disk is authored. The vast majority of authoring programs insert 2 seconds of space between tracks, and during that 2 seconds the index is set to 0. Some, such as Dark side of the moon change tracks with no space so they flow together. When I author an audio CD, by default the authoring software will put the 2 second gap between tracks but I can set that to zero. When burning say 20 tracks to a disk, thats an extra 42 seconds for audio, the 2 second start gap and 2 seconds between each track. I have no idea why they chose 2 seconds, perhaps for cheap CD players when searching backtracks so they didn't land on the last note of the previous track. Also there are 100 frames every 3 seconds of play time, so 33 frames for the first 2 seconds and 34 for the 3rd second. This is the same as DAT which was used as a mastering format for CD, and the data on a DAT tape is exactly the same as on a CD
Any idea why the protection devices failed? Is this an expected wear item? Or was there possibly some other cause such as leaky caps or maybe it was off for a very long time and the caps had to re-form a bit and used too much current? Thanks!
I have a technics sl-pd6 cd changer and though is plays fine for the most part, on some CDs even pressed ones the audio starts distorting and skipping toward the outermost tracks. I've tried lubing the rails but made no difference, what I noticed though is that gravity has an effect on it, if I tilt the player toward the front (lift the back) the cd plays and searches fine! It doesn't happen on all CDs some play fine from beggining to end. Wht do you think it could be?
t0nito The disk spindle height is a little low. I bet if you turn it on its side it also plays fine. The disk spindle tends to slide down the motor shaft as most are just plastic pressed on. Once it drops below the minimum focus height the lens can't go any lower and you looses focus.
I consider myself too young to be following the vinyl hype, but I definitely have a soft side for CDs. What other media format combines the quality and usability with a warm feeling of actually owning the playback media (unless of course you have thousands of them, then FLAC files on HDD would be the only choice)? I enjoy watching CD player fixing videos very much, amazing pieces of technology made for our love of music spring back to life in the hands of a guru. Thank you!
megashtyr I said good riddance to vinyl in the 80s. Now my kids, young adults think they are hipsters and spend 50-70 for 1 album. Then they worry about not having any money for the rest of the month for things that they do have spend money on like their cell phone. I don't understand the hype. Vinyl sounds like crap compared to a good cd or a lossless rip. I still have a good turntable, actually a few of them and I still have some vinyl that was never released on cd but I certainly am not dumb enough to buy overpriced new vinyl.
Hi. Great video. Thank you for making and posting it. I have a Magnavox CDB 650 that fails to track after the first 2 (sometimes 3) tracks/songs. (At that point, it seems to crash and return the pickup to home positions and returns to load condition, as when CD is first loaded in). After the first 2 songs, it begins to emit a high pitch (but low, that I must mute the sound to hear it) whine (not there in first two tracks). Works fine otherwise. Any comments/suggestions greatly appreciated. Thank you much.
I Have watched all your videos, amazing, will you be having a video on the Sony WM-D6C on the cp602 module, my Units speed is out of control, how about would like to work on my Sony WM-D6C for one of you videos,i know you are in Canada i am in the US
Well,, this tutorial was so enlightening. The negative and the positive voltages, following the circuit for voltage losses. Protectors, are they just fuses and are they rated. How can you tell which one to use? Are all of them the same. Did you get it from another unit did you say? Just curious. LOve watching you work. So interesting.
The protectors act like fuses. They are nothing more than high precision very fast acting low voltage fuses called IC protectors. There are a number of different cutoff currents available, and the number means nothing. One marked N15 for example the part number is ICP-N15 and that would be a 0.6 amp 50v. An ICP N10 is 0.4amp and an ICP N10 is 0.25. N20 is 0.8 and N30 is 1.0 amp and N50 is 1.5 amps.
@@nikodemus1able School does help in it's on way. When I was in the Air Force, I attended Aircraft electrical schools all the time. They helped a lot but hands on is a necessity because you get to apply what you've learned in the school. If you don't attend schools then you may miss something that you think you actually know. Doesn't hurt to attend a classs or two and read, read, read, too. Oh, I'm never to distracted in class to absorb someone else knowledge.

I’ve got two Linn CD players with indexing but I’ve never found any CDs that make use of it, I understand it was intended at classical music to allow you to skip between different movements within a piece but was never really used. Edit, I wrote this comment before I’d watched the whole video.🤣
The only CDs I have that used it was a few of the Mangeim Steamroller Fresh Aire CDs. There are a few that should have used it. Dark Side of the Moon for example, and the 3 classics by Jean Michele Jarre, Oxygene, Equinox and Magnetic fields, because the tracks blend together, and there was no gap between the tracks on the vinyl. Even at the band spacing on the vinyl, there was music, the needle just dropped into sound. On the CD release it causes an annoying gap between the tracks.
@@12voltvids You listen to Jaen-Michel Jarre and you had it on vinyl - wow, you must be one the very few Canadians, everyone else is making fun of me. Do you have Equinox by chance? Yes, I'm getting old too, but I still like my music from teenage years. I'm not really crazy about the new 'Re-Mastered' albums or Euro with 15dB Compressor-Limiter build into the music. Comes as J.B.L. on my spkrs, but almost everyone clips the waveforms today - you know what I mean.
I'm slightly disappointed - not because you were using solder wick, but because I was hoping you were going to use it to temporarily short across the fuses. lol Hey, that's what the current limiting on the regulators is for, right? ;)
YUKI JINJUJI Of course. ;) It was more of an in-joke though, as I have done similar things before when working on my own gear, and it's a "trick" often used in repair shops when temporarily testing things. Obviously not a very clever idea unless you know why the fuse popped in the first place, but there are ways to test the circuit before using a temporary wire bridge.
3x There are 4 of them around here, but they aren't hanging around the Shop right now. One day they will show up I am sure. I boot them out because they jump up on things and I have some client equipment that I don't want knocked over.
HAD THE SAME MODEL SONY CD PLAYER WITH THE SAME PROBLEMS............THE 2 IC PROTECTORS N15 ...2 PIN NEAR THE 2 REGULATORS ............COULDN T FIND THE PARTS .........SO MY SONY ENDED UP IN THE DUMPSTER..........
Oh, some assholes whinge about anything. Solder suckers are ok, but not ideal all the time. Keep your chin up, and keep on with the great vids. Warmest regards, Wayne Brill and Nina Evans.
Pretty sure the assholes are people in the service industry pissed off that their trade secrets are being shown off. I am sure if I was still trying to make a living doing this I wouldn't be happy if another tech decided to start showing people how to do it themselves. Back when I was in service, all the local techs would share tips with each other, but we would never fix anything when the customer was watching, because we didn't want them learning our trade secrets and then fixing their friends stuff. But times change. I don't make a living doing this anymore, and I am still in demand, so I make a little fixing stuff, and make much more teaching others how to do it here.

The 1990 release of the CD "MCXMC a.D." by Enigma also had indexes. on later re-releases they changed the index markers to track markers.
I have seen the cdp291 CD player. A common one with the kss240 pickup, and single cd. An early 90s player. Not very much inside of it. Tiny power board, single cd deck thing, and a board for the front controls. The CD player uses a tiny circuit board mounted underneath it.
Do you by any chance repair old PC CDROM players from the early to mid 90's? I have a stack of 2X speed CR-563-B CDROM's manufactured by Matushitia-Kotobuki Electronics Industries LTD of Japan that either no longer spin the disk or if it does it no longer can read the disk. Unfortunately this is the only CDROM drive that I know of that works with the Creative Labs sound cards such as the Sound Blaster Pro2 and Sound Blaster 16 sound cards that still had the Creative marked 40 pin CDROM IDE interface. I can provide you with the needed PC supporting components (Fully working Intel based 386-33 computer) including a working drive to use as test bed for testing these drives as you diagnose and repair them.
One album good for the index function is Rush 2112. Track one is 20:33 seconds and divided into 7 parts. On the LP the parts are actually seperated.
Right, it was a great feature, and underused. One album that they should have used it on, but didn't was Jean Michel Jarre, Oxygen, Equanox and Magnetic Fields. Especially oxygen. Nothing more annoying that having that CD in the jukebox, set in random mode and it crashes in on a track half way through, or cuts off half way through because the disk engineer formatted as tracks (with no space between) as opposed to using the index, so when a player is set to random it plays the entire track as it was supposed to be heard on the album a full side at a time. I ended up ripping the tracks, and stitching them together to make side 1 and side 2 play out as a single track.
What would be the minimum analog oscilloscope specs to have in order to work on vintage cd players and other audio/video equipment like this unit?
10mhz will work fine.
@@12voltvids Thank you! Love your vids and have applied what I learned to actually fix a few things!
It was 15 degrees here in Ipswich UK. As you say, not bad for November, but it was VERY windy here. By the way, what's the big deal with using de-solder braid? Seems absolutely fine to me.
Gotta love those El Nino warm winds.
About the solder wick..I am very young in the game, but not wicking can lead to pulled traces if you don't wick it after the solder sucker..That board was well marked for the test points, that's nice! Pretty neat old cd player, I wonder what DA converter was used?
Jason Brindamour
The da on this one was nothing special. Sony made their own. Some of the high end es players like the 555 or 777 used burr brown and those were really smooth converted. I have a 555es and it sounds so good.

Well we set a record for Nov 22. Got up to 16.8C. Almost beach weather. As I said no jacket required working outside. Even today is pretty warm. Double digits by 11 am.
Any particular reason why you don't use a desoldering pump? I only tend to use copper braid, wet with some flux, when I have a very stubborn through hole.
エステティック Funk
I don't have one and can't justify buying one. I used to have one and it was always clogging up and the boss refused to buy new tips ect. So I went back to solder braid. Works for me. If I was doing this for a living then perhaps but then I would have an air station as well but I retired from electronic repair back in 2003. For the small number of components I need to unfolded the braid works fine
12voltvids That's a more than fair explanation. Thank you for taking the time to answer my question.

I've stopped using grease on CD player rails. I'm now using a drop of light machine oil.
you can do that but if it spills inside the laser you will destroy it
I forgot to show it, but the worm gear on the sled motor also got a dab of the yellow grease.
you have to take some "Molycote G-33" for metal on metal gears/sliders. (orG-68" if you want plastic or plastic on metal). There is no reasonale alternative to go unmarked oils and greases which lack a clear specification.
This may work for some months or even years. but if you want to preserve stuff, don't cheap out on the grease, since a pot will last (nearly) forever.
@@12voltvids YOU ADDED SOME GREASE ON THE GEARS.............N DID NOT SHOW IT.............NAUGHTY MAN
I really enjoyed how you shared your servicing of this CD player. I learned a lot. You're an excellent instructor.
Being that this is an older CD player, how long do you think the optical pickup will last? Is there any way to gauge how long an optical pickup will last?
Thanks, Tom
THOMMGB
optical pickups can last a long time. Most failures are caused by environmental conditions. Smoke, humidity ect. Clouds the lens and internal optics. The spindle motor is more likely to fail with high usage.
Thank you for the quick reply. I appreciate your knowledge very much.

sony stupidly used similar IC fuses in their PVM 40 series monitor power supplies, blows if its been off for long enough that the caps need to reform, i replace them with something that is not as fast blowing because its an unavailable part and because they like to blow open without a fault, i like to use littelfuse 395 series fast acting fuses for the PVMs
I just bought one of these today in Toronto area mint in original box..or $30.not a scratch anywhere... plaus welll but needs a tray belt... any idea where to get a remote for it ?
Not anymore. There used to be a place on Toronto that had all the remotes and accessories. I forget the name but I'm sure they are out of business. Try Amazon.
Do you use/have a proper set of J.I.S. cross point screwdrivers? Though they look like standard head Phillips ones, the spec/profile is slightly different and can cam out the heads. There is a "dot" on these screw heads which almost all Japanese/Asia products use.
Yes I do know the difference. I do have a real Japanese cross point screwdriver. Actually I have 2. That little blue #0 that I use for cameras and walkman is a Japanese cross point. I also have a #1 cross point with a wood handle. These were very popular on Sony beta VCR. Since it is a #1 I don't use it very often as most screws are #2, and I just have a philips which works fine for the few jobs I do.
The Phillips CD900 had index search as well as track search, will that machine play the tracks that are hidden in the pre-gap, Tony Braxton CD Album Secrets had two indexes on the last track which was actually the title track index_1 is the secret part and index_2 is the normal part of the track for players that didn't have the index feature.
DAVID GREGORY KERR
Never heard of a player that can't play a disk. What most hidden cd did was record the bonus track at the end of the last track and put 2 minutes of silence between. A cd player with index would play it immediately and for cheap ones without index they had to listen to 2 minutes of silence then the bonus track played.

Spot on, it seems to be in great condition, the lazer must be A1, like a new one.
What's the hatred for solder wick?, sometimes it's far better than a desolder sucker.
I use both, i find solder wick ideal for clearing solder bridges on smd chips, created by me LOL :-D.
Just read comments. Thumbs down for solder wick, get a sucker.
Naaaa there is nothing wrong with wick, or resin saturated coaxial cable sheild, as i see it.
Expensive for coax sheild.
Use what works.
Though the sucker is very useful it sometimes it will rip of the pads with it, especially on single sided boards, solder wick is much more delicate, but it can also be a nightmare on double sided boards.
tOnito, Yes you need to assess the pcb before deciding, i'm used to using the sucker for through hole parts, if kept clean the sucker works quite well :-).
Also you have to use speed to apply the pump really fast so the solder has no time to cool, if you don't have fast reflexes use wick :-).
Both have their place, the skill is knowing which to use and where. Loving the CDP-55, Dave - a player way before its time, for sure. The sound quality was remarkable for its price point too.
BTW - I owe you yet another thank you; watching your videos has woken my inner-tinkerer, and I have recently resurrected two fluid damaged laptops, repaired a couple of printers, and have a cassette player in hand at the moment. It appears that those of us willing and able to look at stuff are something of a dying breed here in the UK too - - I am never going to make a living at it nowadays, but maybe a wee bit of pin money and the satisfaction of saving stuff from the dump. So, thank you - I had given up on our trade 20 years ago, and here I am pottering about once again.....
I 👍you for solder wick . I would use my super vacuum but it's blocked just like your vacuum and every one else's
23:38 There shouldn't be a pause between tracks - at least on a good CD player. A Red Book audio CD is basically a stream of PCM audio samples (with some extra data sprinkled in for error correction and the subcode, which basically stores the timecode of the CD, there are 75 timecode "markers" per second). There's no "gap" in audio between tracks. '
All a CD player would need to do if you reach the end of track 1 and start track 2 would be just to update the display to say it's playing track 2. it's not like a collection of MP3 files where your MP3 player has to stop playing the track, open the new track, load it into memory, and etc. It's a continuous stream of audio data.
It all depends on how the disk is authored. The vast majority of authoring programs insert 2 seconds of space between tracks, and during that 2 seconds the index is set to 0.
Some, such as Dark side of the moon change tracks with no space so they flow together.
When I author an audio CD, by default the authoring software will put the 2 second gap between tracks but I can set that to zero. When burning say 20 tracks to a disk, thats an extra 42 seconds for audio, the 2 second start gap and 2 seconds between each track. I have no idea why they chose 2 seconds, perhaps for cheap CD players when searching backtracks so they didn't land on the last note of the previous track.
Also there are 100 frames every 3 seconds of play time, so 33 frames for the first 2 seconds and 34 for the 3rd second. This is the same as DAT which was used as a mastering format for CD, and the data on a DAT tape is exactly the same as on a CD
Any idea why the protection devices failed? Is this an expected wear item? Or was there possibly some other cause such as leaky caps or maybe it was off for a very long time and the caps had to re-form a bit and used too much current? Thanks!
James Munn
I covered that. Cracked solder on the 5 volt regulators or perhaps a jammed sled motor due to dried grease causing it to stick.
@@12voltvids I WOULD SAY THE REGULATORS WERE OVERHEATING..................ME I WOULD HAVE CHANGED THEM................MAPLINS HAVE LOADS OF THEM CHEAP
@@nikodemus1able
Bad solder not the regulator. Not hot enough when built.
I have a technics sl-pd6 cd changer and though is plays fine for the most part, on some CDs even pressed ones the audio starts distorting and skipping toward the outermost tracks. I've tried lubing the rails but made no difference, what I noticed though is that gravity has an effect on it, if I tilt the player toward the front (lift the back) the cd plays and searches fine!
It doesn't happen on all CDs some play fine from beggining to end. Wht do you think it could be?
t0nito
The disk spindle height is a little low. I bet if you turn it on its side it also plays fine. The disk spindle tends to slide down the motor shaft as most are just plastic pressed on. Once it drops below the minimum focus height the lens can't go any lower and you looses focus.
12voltvids Thanks I'll try lifting the spindle a bit to see if it improves
Do you repair cassette players as well?
I consider myself too young to be following the vinyl hype, but I definitely have a soft side for CDs. What other media format combines the quality and usability with a warm feeling of actually owning the playback media (unless of course you have thousands of them, then FLAC files on HDD would be the only choice)?
I enjoy watching CD player fixing videos very much, amazing pieces of technology made for our love of music spring back to life in the hands of a guru.
Thank you!

I said good riddance to vinyl in the 80s. Now my kids, young adults think they are hipsters and spend 50-70 for 1 album. Then they worry about not having any money for the rest of the month for things that they do have spend money on like their cell phone. I don't understand the hype. Vinyl sounds like crap compared to a good cd or a lossless rip. I still have a good turntable, actually a few of them and I still have some vinyl that was never released on cd but I certainly am not dumb enough to buy overpriced new vinyl.
Howcome You Dont Zoom in With the Camera So All Viewers Can See Up Close?

Hi. Great video. Thank you for making and posting it. I have a Magnavox CDB 650 that fails to track after the first 2 (sometimes 3) tracks/songs. (At that point, it seems to crash and return the pickup to home positions and returns to load condition, as when CD is first loaded in). After the first 2 songs, it begins to emit a high pitch (but low, that I must mute the sound to hear it) whine (not there in first two tracks). Works fine otherwise. Any comments/suggestions greatly appreciated. Thank you much.
wow, I thought it was going to have a linear motor by seeing how fast it changed tracks.

Which specific molykote grease are you using?
Well,, this tutorial was so enlightening. The negative and the positive voltages, following the circuit for voltage losses. Protectors, are they just fuses and are they rated. How can you tell which one to use? Are all of them the same. Did you get it from another unit did you say? Just curious. LOve watching you work. So interesting.
The protectors act like fuses. They are nothing more than high precision very fast acting low voltage fuses called IC protectors. There are a number of different cutoff currents available, and the number means nothing. One marked N15 for example the part number is ICP-N15 and that would be a 0.6 amp 50v. An ICP N10 is 0.4amp and an ICP N10 is 0.25. N20 is 0.8 and N30 is 1.0 amp and N50 is 1.5 amps.

Extraordinario 12Voltvids
I’ve got two Linn CD players with indexing but I’ve never found any CDs that make use of it, I understand it was intended at classical music to allow you to skip between different movements within a piece but was never really used. Edit, I wrote this comment before I’d watched the whole video.🤣
The only CDs I have that used it was a few of the Mangeim Steamroller Fresh Aire CDs. There are a few that should have used it. Dark Side of the Moon for example, and the 3 classics by Jean Michele Jarre, Oxygene, Equinox and Magnetic fields, because the tracks blend together, and there was no gap between the tracks on the vinyl. Even at the band spacing on the vinyl, there was music, the needle just dropped into sound. On the CD release it causes an annoying gap between the tracks.
Invisible Touch has a track that takes advantage of the index feature. That's the only CD I have that does that.
12voltvids didn't the first CD run of Pink Floyd's Wish You Were Here have indexing?
You have Linn, but no Stereophile Test CD2 - from Track 15 it's all but Indexing. Actually very useful CD with test tones and other signals.
@@12voltvids
You listen to Jaen-Michel Jarre and you had it on vinyl - wow, you must be one the very few Canadians, everyone else is making fun of me. Do you have Equinox by chance? Yes, I'm getting old too, but I still like my music from teenage years. I'm not really crazy about the new 'Re-Mastered' albums or Euro with 15dB Compressor-Limiter build into the music. Comes as J.B.L. on my spkrs, but almost everyone clips the waveforms today - you know what I mean.

I'm slightly disappointed - not because you were using solder wick, but because I was hoping you were going to use it to temporarily short across the fuses. lol
Hey, that's what the current limiting on the regulators is for, right? ;)
ElectronAsh
Oh you mean like EVERY shop did? Yes I remember very well little jumpers across icps on many things.
No sir I would rather sacrifice a few fuses than cause a explosion
YUKI JINJUJI
Of course. ;)
It was more of an in-joke though, as I have done similar things before when working on my own gear, and it's a "trick" often used in repair shops when temporarily testing things.
Obviously not a very clever idea unless you know why the fuse popped in the first place, but there are ways to test the circuit before using a temporary wire bridge.
who objects to solder wick? i mean what?

Pretty sure the assholes are people in the service industry pissed off that their trade secrets are being shown off.
I am sure if I was still trying to make a living doing this I wouldn't be happy if another tech decided to start showing people how to do it themselves. Back when I was in service, all the local techs would share tips with each other, but we would never fix anything when the customer was watching, because we didn't want them learning our trade secrets and then fixing their friends stuff. But times change. I don't make a living doing this anymore, and I am still in demand, so I make a little fixing stuff, and make much more teaching others how to do it here.
