SONY Walkman Repair

[@pjeff18]

What can I say other than wow and thank you ! This is my Walkman. Purchased with my pocket money when I was 15 from that famous catalogue store and cared for like nothing else until 3 years ago I put in a Panasonic zinc battery and forgot about it . I left it under my hifi cabinet and stumbled across it this year to find a leaky battery . The rest, well you can see for yourself ! Mark - your skills and patience are like no other - massive respect and a huge thank you 👍🏻 Paul

[@madtopp]

yep i agree with you he has done 2 of my hi-fi items one being the pioneer sx550 and he blew me out the water with how he went above and beyond with the repair i am waitng for the repair video on the other one i gave him and i recently gave him something else to sort out and he is a great guy as i have had the pleasure to meet him in person and he always has time for a chat when i drop of stuff to him

Never leave alcaline or zinc (you've got to be kidding me) batteries in any device when not in use. It's what kills them all.

Amazing attention to detail. There are very few people who would bother with repairs like this today. Well done Mark.

[@nevillegoddard4966]

@capelhanbury-tension1288 No doubt about that! I wonder what Mark charges his customers for these repairs on this 'ancient' equipment though? He's probly spent 6 hours on this Walkman, so at normal rates that's gotta be easily $300 - $400, or £150 - £200? Are these 'love' jobs where he basically repairs stuff just cos he likes repairing stuff, or are these repairs just for friend's stuff? Or does he charge normal rates & his customers are prepared to pay way more than the unit is worth, just because of the sentimental value or 'uniqueness' of their device? I mean, it's always great to repair something to keep it out of landfill & extend the lifetime of it, but there are economic considerations I'd have thought!

[@russellforrest1730]

OMG! When I was doing this kind of work, years ago, we had a deadly acronym BER = Beyond Economic Repair. A repair like this makes no business sense at all, but completely fascinating to watch! Had my heart in my mouth when you started to lever up that actuator arm, easy when watching, but thought this way be dragons... Wonderful fun, to watch anyway... more than 30 mins just flew by. Thanks so much for sharing! Been binge watching all the fixes - so impressed with your skills and patience! Kudos!

[@shill6449]

Too true. But there is money in it, where the owner is aware of the cost, and is happy to pay-up. There's companies out there, selling fully serviced, 30+ year old Nak's for £7,500

[@adrinathegreat3095]

He said he spent hours scraping away and just trying to straighting out a piece of metal, plus disamanltling testing and resembling time, got to be looking at 6 hours an easy £300 repair for a £5 Walkman. It's got to have sentimental reason otherwise it'd never be worth it

[@LilMissMurder3409]

Having seen many tape deck repairs on this channel and how bulky and complex their tape mechanisms are; it gives me an awestruck appreciation for what an engineering masterpiece the Sony Walkman really is. And it runs off 1.5v with decent battery life, too.

[@calebcourteau]

I just stumbled upon your channel today and have been binge watching your videos. Your skills are extraordinary but what really makes you stand out is your upbeat and cheerful personality. You have such a great attitude even when confronted with really difficult repairs.

[@chloemarietaylor4036]

I had this model of Walkman back in the mid nineties. I seem to remember it had similar problems. While pretty handy repairing stuff I took one look inside and failing to dismantle it I gave up. Seeing this video having to desolder stuff to dismantle is probably where I got up to, without the internet or a service manual I had little chance. It was a great unit, auto reverse, track skipping etc.

[@NotXboxiie]

i dont think i ever got so hooked into a repair channel... i only learned about it yesterday and have not touched my Xbox controller as long as am used to. Mesmerizing from start to finish.

[@davidsmith-ih2kk]

I hope you're going to show this video to the owner, Mark. That's not just a small amount of battery leakage. It's very large, and it looks very yucky. You are incredibly skilled Mark to do all this and not just electronics you are a mechanical repairer as well. Love watching a professional at work and you are certainly in that category. Thank you for sharing a part of your vast skills and knowledge with us Mark, it is very much appreciated, and just so incredible to watch you work Keep up the good work, Mark. Great videos.

[@laoluu]

One should think they finally developed a non-leaking battery. Leaking batteries are an endless hassle, especially in clocks, remote controls etc. When the thing stops working, it's usually too late. You, sir, are an excellent technician and repair man. Hats off!

Have to repeat what others probably have stated - Mark's patience and ability to stick with a problem and see it through astounds me. This video really highlights his true ability to solve problems. Great presentation as always. The word genius in many ways applies. I have fixed things in the past but would never gone into the intricate details to try a repair like this.

In another episode ... Mark mentioned using his cell phone camera to keep track of where everything went ... I've done that with the incredibly complex gearing in Laser Printer and copiers, I used to be able to do that from memory, but memory gets fuzzy with age and so do fine motor skills as you get arthritic !!

[@johnmarchington3146]

One could almost say it's a masterpiece of miniaturisation, with all those nylon (I presume) gears. What is doesn't allow for, unfortunately, is a decent flywwheel to provide speed stability. Battery corrosion is certainly the bane of portable electronic devices. Another marvellous video, and thanks once again for showing us how it's done.

[@nevillegoddard4966]

@johnmarchington3146 Actually John, each drive capstan in this Walkman has a probly 1 inch diameter disc as part of it, & these become the flywheel; one for each direction of travel.

[@coastwalker101]

These Walkmans were the pinnacle of mechanical and electronic consumer engineering of the time. They are amazing. Now we have a chip, a battery, touch sensors and a couple of sockets to do the same job - all of which has probably disappeared in the cloud by the time you read this. I have a pile of them I used to take on skiing holidays in the 80's and 90's to record local radio and to rock to on the piste. I imagine the belts have all gone by now but I might take a look sometime before I croak.

I've learned something with every video I've watched of yours. Today's lesson - put little jumper leads on things if you need to test after you've desoldered the board. Why have I never thought of that! Love your channel, keep up the great work 👍

[@paullangton-rogers2390]

I have to admire you attempting to even repair anything small from Japan! The last time I attempted a similar repair it was an absolute nightmare. The device was a Kenwood pocket sized cassette player (hardly bigger than the cassette itself!) no sooner had I managed to open it, than springs started flying everywhere and microscopic screws were lost just by breathing near them. Servicing that level of technology is not something the average technican can do. The parts are so tiny and all the PCB's are surface-mounted components. Too much heat does a lot of damage. You need very specialised equipment and the technical skill. When you see factories in Japan it's astonishing (I worked for a big Japanese electronics corp) it's like a hospital bio-hazard environment with guys wearing white suits with hoods and white gloves. Dealing with small Japanese electronic devices is often similar to watchmaker repairs. If you've ever seen what goes into servicing, assembling watch movements you'll see the incredible amount of skill it requires due to sheer complexity and precision of the tiny parts.

[@jimsimpson1006]

Hi, technically, it is absolutely amazing! Small and very good made. Good to repair this. The thing is, today no one would pay (for the time spent) to make it work again.

@@DeePaignall Really 😊... Well, I can't even remember the last time I listened to anything on a cassette or even wanted to. If I did have a need, the last device I'd think of for that purpose would be something like that Walkman. Btw, I have an old Sony CRT television in my garage that's in perfect condition and if you can carry it you are welcome to come and take it away. 625 line low resolution goodness just waiting for a new home 👍

[@DeePaignall]

@@chillidogkev "Sooner or later, everything old is new again". Cassettes are making a comeback - crazy but true - and if you'd heard that walkman play it might impress you more than a 128bit mp3. 'Retro gaming' is a thing too, so someone somewhere would prefer your crt over an OLED to play their video games on, well done for keeping it! Saving devices like these is fun and saves a bit of history too - personally I recommend it.

[@davespagnol8847]

@@chillidogkev I wouldn't buy music or record it on cassettes, but I have a load which have been in my brother's loft for years. Getting something to play them on, in reasonable condition, would allow me to play them into my computer and digitise them. Sadly, new cassette mechanisms are rubbish. The solution would be to buy refurbished. Mend-it-Mark's videos are not just fascinating, they show what can be done.

Nice job Mark, it's amazing how the corroded battery just eats through the plastic and embeds itself. I like the way you calibrated it. It looked like you used a tape with a set frequency, then just tuned it to match that recorded frequency.

[@mikek8626]

Hey Mark, love your vids! Distilled white vinegar will neutralize and help clean up the potassium hydroxide electrolyte leakage from alkaline batteries (Vinegar is an acid and potassium hydroxide is a base). may even get some good fizz action, lol. One just wants to be sure to flush out all the vinegar when done. Distilled water then IPA has worked for me.

Nice repair, i was a bit nervous when you started bending that arm though 😀. Very educational for when/if i'll need to dig in mine some day. I do have a couple of these myself, well mine are the EX510 (without remote), one mint condition in box and one kinda rough used. I've replaced the belts in both, extremely easy, like a 10 minutes job at the most. What's sort of tough is to find the proper 0.6mm belt for them. The model 510 was also my very first "real" Sony Walkman back in 1994, but that's long gone. Great work man, i always enjoy your work.

And I've only got so far as to just replacing the belts in these Walkmans back in my "teenage" years.

I know this video was made over a year ago, but just wanted to give you a little advice from one electronics technician to another. Hydrogen peroxide works extremely well to remove damage caused by a leaky battery. . It takes a few minutes for it to have an effect and needs agitation from a brush or other object to help remove the buildup but it will get rid of all of that sludge even on rusty metal. It restores it to almost like new.

I had a Sony WM D6C Pro Walkman. Very high end recorder. Incredible device for it's time. It worked great and it was expensive. I used it to record many local rock band shows and to record interviews of famous artists who came to town. I used it a lot. But after many years I had switched entirely to digital recording devices which were cheaper and better. In 2010 I pulled the Pro Walkman out of a box and found I had left the batteries in. Something I try to never do. They had corroded and part of the PCB was etched away. I started doing the surgery and it got more and more involved. Then I stopped and thought "What for?" The digital devices are far superior. I wasn't ever going to record a cassette again. I lit a candle and stood it on the soldering iron station on my lab bench. I said my so longs, gave it a last salute, and pushed the remains of the pro Walkman off the edge of my bench into the trashcan. I'll always remember it and I will always know where it's final resting place is. The county dump. I shed a little tear every time I drive by. And I thank goodness I don't have to mess with cassettes ever again.

[@nevillegoddard4966]

@kthwkr I had a Sony Walkman 'Professional' years ago too. I don't know its model number but it was black & had a leatherette case, Dolby C & a led bargraph level meter & could play & record onto 'metal' tapes as well. It cost me a fortnight's or a month's apprentice wages back then! Then one day the playback speed went stupid, & was varying up & down twice per second. It wasn't that old, so I contacted Sony & I actually got to speak to a Sony service tech! He was very helpful, & on his advice I bought a service manual & the two little surface- mount I.C's he thought were most likely causing the fault. Luckily I was able to remove & replace both I.C's successfully & the speed modulation problem was fixed! Such a beautiful, 3 colour original factory printed circuit diagram & service manual I had never seen the likes of before or since! Sadly, my Walkman was stolen from a friends house but I still have the MDR-70 headphones that came with it. The earpads that sort of stretched over the earpieces are pretty deteriorated now but I'd like to replace them if I can. Even today, in a quiet room, these headphones sound like they've got subwoofers in them they're so good! I fell in love with Sony gear after that!

I admit I cringed a bit when I saw you bending that lever! Glad you could fix it! I would have used some rust remover - I found that citric acid works very well for me. Carefully obviously, but I would have tried flushing that part more. That said, great video and thanks!

I liked working on Sony gear pre-Interwebs as they thought about service techs from the design stage. Service manuals were easy to find. They were open about service code locks to third party techs. Ordering components was easy, even one manufactured by a 3rd party just for one model. They had detailed alignment and calibration instructions. They used to have bits on the cases to temporarily hold boards in place upright when servicing. I'm not sure how things are now. There are far fewer AV repair places still open while most citiesh ave heaps of mobile telephone repair shops.
