So after the success of the last discman I got up and running I though I would shoot a little higher. I've been bidding on broken D-15's and D-25's (two of the most beautiful players in my opinion) left and right with little luck. Then while I was checking new listings one day I found the perfect victim ... erm I mean perfect repair target. The unit looked in pretty good physical condition and the price was definitely right so I bit the bullet and placed my order. Let's find out if that was a wise decision, or if I bought a very expensive paper weight ...

Hey sjm4306: Have an old D-150 from 1990, always kept an eye on it but somewhen I got the problems described: player stopped to play after 30 seconds, couldn´t change tracks anymore etc. Broght it to a "specialist" some 15 years ago, paid him to repair but he left it with the problems and I forgot about it. I have no clue about those players and how they work exactly but today I saw your video, found the old player, opened it, found the mentioned middle gear seized and ..... repaired it. It runs again and still sounds as 1990! You made my day! Thanks a lot for your video! 👌🏻

Thanks for this video! My D25 would also power on, but wouldn't play. Sure enough, the same plastic cog was seized. I was able to get to the frozen cog by removing just the power supply board/battery compartment. The C clip was easy to remove, but much harder to reinstall, but in the end 'Success'. My D25 is playing again!!

HI, I got a non working D150 today to keep as spare parts for my working D150. I had a look inside to see if I could fix it ,after a few minutes I knew it wasn't the laser so I had a look online and found your video..... fixed! thanks

@tnarch Год назад

Your video just now helped me fix one i bought with defective gear. I had one with serious skipping issues, but found another one for 20 euros and i took the risk buying it. It seemed to work but had no movement to its laser. I figured out that the middle gear was stuck and it broke into pieces when i pressed it a little. The same gear from the one i had from before was perfect, i cleaned it with isopropyl alcohol, and after lybricating it i placed it with care to the new one. Now it works perfectly, and i have one as spare... :-)

@dustinzilbauer7582 9 месяцев назад

I owned the Sony D-25, which was released a year after this unit, in 1989. I worked a summer job that year to buy it for $300. It was nearly identical to your unit. I think the main difference was a 4X oversampling digital filter. The build quality of these discmans was unmatched for the time. The sound quality was very good but it lacked any kind of bass boost and the sound quality of earbuds for the time period tended to be very tinny with very little low-end at all, but they went VERY loud and sounded great hooked up to a home audio system.

@JasonMcFly 4 года назад

I've had a lot of vintage Discmans, the older ones all do that thing where you can still hear audio when the volume is all the way down. Weird and kinda cool imo. It's not your headphones, haha. You should get some nice audiophile headphones if you don't already have some. The vintage Discmans are well regarded for their sound. I have a few that don't work or partially work. Your videos are inspiring me to crack 'em open and have a look!

@tengoretrotengoretro2882 3 года назад

@sjm4306 Great video! I was curious, there is a c-shaped piece of metal that partially blocks the middle gear (and fully blocks the front of the worm gear). You didn't show the actually pulling off of the gear. How did you do it with the c-shaped piece of metal partially blocking the middle gear? Did you bend or remove that piece of metal before pulling the gear off?

@sjm4306 3 года назад

Thanks, iirc I somehow removed the metal piece non-destructively (I dont remember having to bend anything so it was probably just clipped on).

@aerotraveldji 6 месяцев назад

@HEPATCA 4 года назад

I believe the D9 and D15 use the same wall transformer, 9VDC @ 1A. Center pin NEGATIVE which is kindof unusual. Also note that most coaxial power plugs have a smooth inner bore, but the discman jack used two springs on the inside to grip with the center conductor pin. That's why your power connection is a bit temperamental.

@sjm4306 4 года назад

Ah that explains it, I'll have to see if I can source the same plug from the original adapter or design something custom to more reliably work than what I currently use.

@benchiang8235 4 года назад

I just got in a D-15 this week. It lights up but the laser is in the far position and doesn't move back. I'm going to remove the old grease and apply some white lithium grease later today. Thanks for the video footage of the D-15's interior!

Your welcome, and good luck getting your D-15 back up and running!

@Mike-nf6nf 4 года назад

@@sjm4306 I just got it opened up and cleaned off the worm gear of its old grease. Applying white lithium grease and 3-in-One oil to it shortly. Does the small power supply PCB come out easily for you? I'm having trouble getting it out after removing the 2 small silver screws holding it in.

@Mike-nf6nf 4 года назад

I got it to play a CD! But it doesn't always spin up the disc. There's some glitchiness, possibly from playing it upside down. I'm not sure what keeps the disc motor from not moving sometimes. Maybe it needs a tiny drop of oil? It sounds NICE, as you know already. The DAC is a Burr Brown PCM60P.

@sjm4306 4 года назад

I was able to wiggle the power board out (though I don't remember specifically how). The motor not spinning isn't due to anything mechanical, it's the laser not detecting the disc. If it plays upside down but not rightside up and skips a lot then that's a hint that the caps have gone bad or the calibration gains in the laser/motor servo circuits need to be tweaked. Additionally I found my lid detect switch was quite dirty and needed to be cleaned or it wouldn't turn on half the time because it thought the lid was open.

@Mike-nf6nf 4 года назад

@@sjm4306 It's working a lot better today! I can use it upright and the CDs spin. Maybe the first disc had issues with it. The only problem now is the constant noise. I can't tell if it's from the CD scraping against the player, or the plastic piece underneath the lid which rotates and clamps the disc in place. Should I apply lithium grease or another lubricant to the inside of the rotating plastic clamp?

@onyx2002 4 года назад

Great Video,, I have a sony D-35 /D-350 that spins up , but skips badly and/or won't read the disc at all unless held at a 45 degree angle or upside down. I purchased a new spindle motor on the advice I got from forums etc.. But now reconsidering based on your success with replacing capacitors. Luckily i havn't started yet, and found the service manual and schematics. I am proficient in soldering etc.. Question -> is the motor able to spin easier upside down or at an angle thus not requiring the extra buffer from the capacitors.. that seems to make sense ? Could you elaborate .. Any advice greatly appreciated as I absolutley love these vintage Discman ... Thanks

@sjm4306 4 года назад

It's almost 100% not the motor, but the caps. The problem is bad caps decrease in capacitance and the compensator circuits for laser tracking are dependent on those caps to function properly. The reason why it works at an angle or upside down is you are changing the effect of gravity, which is changing the nominal starting point for the compensators so that they become within working range with the bad caps in the circuit. To properly fix this you really do need to swap out all caps and give the board a good clean in case any electrolyte leaked out.

@jjyst5 3 года назад

@janczajka6749 2 года назад

Thanks to Your video I have managed to get my D-150 to work, thanks! The middle gear was stuck, just like in yours, I lost the C clip though... Ordered the smallest ones off AliExpress, hope they'll fit. However, mine has a problem with volume control potentiometer, makes cracking noise when moved and heavy distortion when on minimum. Once I get the c clips and some proper grease I'll open it again and try to remove the top PCB to gain access to volume control. In the meantime I'd like to make a custom battery, but with the ability to charge through the player. Do you think some Li-Po battery with built in protection would be enough to safely put it there, or do I have to design some additional circuits? On the side note, mine also seems to have been opened before, but it lacks the additional small PCB yours have... Wonder what it might be for. Side note 2 - it's loud! I'll have to invest in some higher impedance headphones, since my Brainwavz HM5 are almost too loud on minimum volume. Sounds great though.

@sjm4306 2 года назад

For the lipo if you'd like to both charge and use it while in the battery compartment things get a little complicated. First of course you'd need to integrate a lipo charging circuit inside the battery to handle safely charging the lipo. Additionally you'll need a sort of changeover circuit to detect charging to disconnect the battery and connect it through the charger module. Likewise when it's not charging it should disconnect the charger module and instead directly connect the battery. The reason why this is necessary is most lipo charger modules aren't bidirectional so the battery output and charger input terminals are separate and cant be shorted together.

@JimmyEng 11 месяцев назад

I lost my c-clip as well. If your AliExpress order worked, would me mind putting the details of the item/part I should order?

@punarny1 Год назад

Fantasic video. I have a D250 and bought a LIPO off Ali Express which works great but my sled is stuck too. Just going to remove the back and see if some penetrating lube will work instead of tackling that dreaded C clip.

@sjm4306 Год назад

Just be careful that whatever lube you use is plastic safe and doesn't contain petroleum products as the gears are notoriously brittle/sensitive to crumbling.

@punarny1 Год назад

Thank you. I got it working 😊. Your video was key thanks for posting 👌🏻. I moved the gear with my finger to start with, it was stiff then sprayed WD40 on and almost instantly the gears started moving. Give it a few more drops and sorted. Thank you 🙏🏻

great video thank you. I just found my old Sony D-15 in a box that has not been used for 30 years. I realized that it will not power up with just any DC 9v adaptor. Seemed to worked with a SONY DC 9v 60Hz 10W 600mA (might have been the original) It powers up and recognizes the tracks but will not play (no sound) so I am guessing it has the same issue as yours with the seized gear. I am afraid fixing it might be beyond my abilities any suggestions for Toronto/Canada? I think it will be worth spending a few $ to get it working as they dont seem to make them that solid any more. Thank you

Hi, a capacitor broke off of the circuit board of my Discman. Connected to the capacitor was also a small black piece which allowed the capacitor to connect to the circuit board. Together the black piece and capacitor broke off clean from the board. Do you know if it's possible to repair the unit, perhaps by glueing or soldering the black piece back to the circuit board? Or by another means? Thanks.

@sjm4306 2 года назад

The black piece is only a plastic base and not required for the cap to function properly. If the cap broke off it's likely it leaked and corroded the metal legs that connected it to the pcb. To fix it you should first clean the spot around the cap with some isopropyl alcohol, and then you can solder a new cap on (with the same voltage and capacitance rating as the original one, and make sure to match the polarity, the negative/positive sides should be marked on the pcb silkscreen).

I have D-15 in pristine condition. not a scratch. owned since new in '88. have all parts and original box. But, same issue - plays about 20 seconds of 1st track and stops reading. you can hear it hunting, but does not reengage. would be great to get it running. thoughts?

@sjm4306 4 года назад

It's very highly likely the middle gear in the laser sled drive mechanism is seized like on just about every other discman from the era I've fixed. There is also a chance that it could be bad capacitors.

@AnykaCalin 2 года назад

Hi there , I have an issue with my d-15 , seams like the problem is there’s no red light into the laser , other then that everything works well , laser moving back and forth even up and down trying to read the disc , any idea what could be wrong with it. I really appreciate if you can give me the advice. Thanks in advance .

@sjm4306 2 года назад

Sounds like the laser is very weak or completely dead. The wavelength is neat infrared so you should be able to see an little reddish purple light from the lens (dont look directly into it of course, but from an obtuse angle). The problem is getting a replacement will now be next to impossible other than scavenging from another working discman with the same laser.

@sjm4306 4 года назад

Oof, that sucks. A better alternative to scrapping another dead discman just for the gear would if someone with a good gear made a mold of it in silicone and then could cast replacements in a tough resin. Alternatively it may be possible to CAD model it and 3d print it in nylon like material using an industrial sla printer.

A more modern high end cd deck will tend to have better reliability and more outputs including opticial/coax digital out. In terms of analog audio out though these vintage high end portable cd players are really good, with insanely low noise floor and they sound great when paired with a good set of headphones or a good amp and speakers. It really depends if you want something small or something large. In comparison to more modern portable cd players though (anything made late 90's and on) there's no comparison in terms of quality.

@nomsg7942 3 года назад

great video! i jus found one at a thrift store, however it needs a replacement laser, would anyone know what that part number would be called? which laser?

@sjm4306 3 года назад

If I had to guess, the laser is more likely fine but it's the caps in the focus/tracking circuit that have gone bad, thus preventing the laser from seeing the disc.

@nomsg7942 3 года назад

@@sjm4306 so it turns on, spins the disc, and i can see and hear the laser head hunting, but also, i tried what u did on thr D-8 video, where u pushed the laser all the way back to see if itll go back to the beginning, and it didnt go back to beginning.

@@sjm4306 my 2 repair guys i usually go to both think its the laser, but i have a feeling they are just being lazy cuz they didnt even bother opening the unit. ill gladly pay u to have u take a look if u have the time and are willing! 🙏🏽

@sjm4306 3 года назад

ah that hints that the gear is stuck just like mine which is preventing the laser from moving (which is obviously necessary for it to read the disc). This can go one of two ways, a simple job of removing the middle gear/cleaning/relubricating or worst case the gear is so fragile with age it cracks and a replacement gear will cost ~$30 ordered from china.

@@sjm4306 with ur guidance, i mustered enough courage to open up the unit, and discovered indeed it is that gear! and its definite old and the teeth is really brittle, would u happen to have a link to product page of that gear? or what its called so i can purchase online? thanks so much! i cant believe both my guys that i usually go to both misdiagnosed the issue as the pickup lazer.. smh, regardless.. i really appreciate ur help!

Hi @sjm4306. I have a very nice d25. Unfortunately the gear cracked when I tried to pull it off. The other 2 gears move freely . Slider was lubed and works great. Where can one get a replacement middle gear. I assume buy another d25 on eBay selling for parts? Thanks...

@sjm4306 3 года назад

There used to be a few sellers on ebay and aliexpress who sold aftermarket replacements for around $30 a piece (not cheap but still better than scavenging from another discman) but haven't checked in awhile.

@id_you_tube 2 года назад

Hi @sjm4306 I finally got a replacement gear from a Chinese source. The gear looks good. Someone else asked how you get past that metal C ring in front of the gear. You said it popped out. I can’t get it to budge. Do you remember any more details on how you got the metal c ring off without damaging or bending it? There’s no way to get the gear in there without removing the metal c ring.

@sjm4306 2 года назад

Turn the clip so the gap is towards you and use something kinda sharp like a needle/pin/small screwdriver to carefully pry at the gaps near the botton of the clip. I'd suggest putting some cloth/bluetack on the clip's bottom to catch the clip when you get it off so it doesn't ping off. To reattach you'll need some small needlenose pliers to squeeze from the top and force the clip into the groove of the metal shaft.

@id_you_tube 2 года назад

@@sjm4306 Hi sjm. Thanks for the response. I got the clip off (it is going to be crazy hard to get it back on). I have the gear in place and i rotated it a few times and the sled moves. How do you get the little o washer back on? Does it slide back on or do you put it on like a washer into a screw?. I tried several times with tweezers and almost lost it a few times. It is insanely small.

@sjm4306 2 года назад

Try using something like a pair of tweezers and the eraser end of a pencil. Use the tweezer to position the clip and the eraser to apply pressure forcing it onto the metal shaft. You may have to slightly spread open one end of the split on the clip to get it started. It's trial and error in the end but just go slow and be careful and it'll get back into place eventually. Good luck!

@jd_99 2 года назад

Question: How do you actually get teh clip off?

@sjm4306 2 года назад

A pair of tiny screw drivers or pins, lots of patience and just watch out for it pinging off.

Successfully determined my D-15 had a seized middle gear. Went to remove it and it was so brittle it snapped. Anyone have any idea on where to find a replacement (other than another unit smh..)

@sjm4306 Год назад

There are replacements available on ebay ( ebay.us/wtKEnH ), kinda expensive though for a plastic gear but I guess it's a niche product so they get away with raising the prices quite a bit.

@@sjm4306 just picked one up on eBay. Thanks for the tip. It was around 20 bucks with shipping but my D-15 was only 10 at a garage sale so all in 30 bucks? Not bad!

You can use the kind made for electric razors/hair shavers. Let me know how it goes.

Bin looking for a original charger for this one, but cant find one, do you have any code or nr. on the charger your using?

@sjm4306 4 года назад

I believe the adapter is 9V (probably 500mA or more should be plenty). You'll have to double check polarity but pretty much any 2.5mm jack diameter adapter with those specs will work. For testing in this video I rigged up a lithium battery to a boost converter. Since making this video I 3d printed my own rechargeable internal battery.

I've just picked up a sony d-99 which won't spin/read the discs. I've freed off the middle gear but still no luck. Any ideas?

@sjm4306 3 года назад

The fact that it wont even try to spin the disc points to maybe a power supply problem. I'd check all capacitors and inspect for corrosion on the board.

@davidhenderson9197 3 года назад

@@sjm4306 thank you for the reply. 👍 There don't appear to be any corrosion on the board but I haven't checked the caps. Where did you get the replacement caps from?
