- Hi, this 'trying to fix' video shows me attempting to repair an old 1991 Sony Walkman Model WM-2011. I will be doing 7 other Walkman cassette players over the coming weeks.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince. - แนวปฏิบัติและการใช้ชีวิต

Yes!! This is your best video. (Totally not biased because I'm obsessed with Walkmans...)
Elliot, nice to see you over here. I heard from other viewers that you have quite a few Walkman videos :-) I will check them out this week (might help me with the others).
@@Mymatevince Nice one! Drop me a line if you get stuck!
Will do mate :-)
Got 2 psp go to be fixed how cam I send them to you thanks black and white you can keep the white
you probably dont care but does anybody know of a tool to get back into an instagram account..?
I was stupid lost the password. I would love any help you can give me!
Usually on a single-layer board like this, if it's just a crack in the PCB, I tend to remove the solder mask around the crack, and then just flow solder across the gaps. A drop of thin epoxy into the crack will give the board some structural integrity after you're done soldering it.
I do that some times, that or use component lead cut-offs :)
That was a pretty good fix for not having had to deal with this sort of problem before. Two remarks:
1. It is common practice to epoxy a broken board back up for mechanical support.
2. Good job wrestling those ultra short wire links, but it may have been a lot easier to run some longer loops instead. It's not like DC current cares much about the finer points of routing, and it looks like you're well away from any critical areas of the board in terms of signal.
I anticipate a whole lot more bad belts in this series, along with bad electrolytics and misc. contact issues. On the other fancy Sony that was only showing the time (not sure about the model, but looks like ca. 1988-1990), I wouldn't be surprised to see major issues with leaked SMD electrolytic caps, including board contamination and damage. It's a big problem in all their more highly integrated products from about the mid-'80s to mid-'90s. Video cameras. Shortwave receivers. Head amplifiers in DAT decks. Not sure what else. It's a real shame, as some of these were some really well-engineered products otherwise. Note how the lowly WM-2011 uses conventional through-hole electrolytics.
Oh, and the mysterious rechargeable battery allowing it to keep the time is probably a goldcap... a supercapacitor. If you only need a few microamps, even a little 0.047 F part will keep things running for a good while. Those occasionally fail but on the whole seem to be decently reliable. (Unless you happen to mount them behind a warm VFD and mistreat them by using a barely-functional-when-new microprocessor reset circuit, like a tuner manufacturer who shall not be named. Apparently a certain Microsoft gaming console also seems to have some bad luck with them.)
Thanks for the tips and the possible issues with the other Walkmans :-)
I'm old enough to have owned an old Aiwa model that was thin, solid and all metal. I loved that dang machine! It was from the very, very early 80's. My father brought it home from Japan while on a Navy cruise. What a joy that machine was!
I also own an Aiwa (with radio and Equalizer) and a Sony. Those things were top quality engineering at their time. I tried to dismantle and repair the Aiwa (loose tape door and headphone jack not working) and I think that repairing a modern handheld console is easier. It has tiny tiny microscopic screws, all things were very tight together, it is easy to drop little pieces and never find them. Just like Vince said, it usually is an issue with the rubber bands, they generally get dry, loose or rotten, also the little motor that rolls the cassette tape dies and has no strength to turn.
In my case, there are no schematics nor technician's manuals for the Aiwa around the Internet, so it is pretty hard to get over the issues that come across.
I cannot believe you fixed this. Amazing troubleshooting and patience with the soldering.
Can't wait for episode 2: "Revenge of the Walkman", episode 3: "Rage of the Walkman", episode 4: "Return of the Walkman", episode 5: "The Walkman of Shame", episode 6: "Walkman, Texas Ranger", episode 7: "I'm Walkman here, I'm Walkman here" and last but not least, episode 8: "Walkman".
And it will be released as a set "Walkman Complete"
Episode 2 should be "walkman 2 : electric boogaloo"
Can't wait for the Blu-ray box set. Walkman: The Keep on Walkman collection
So..is Episode I : The Walkman Menace?
these vids are truly inspiring. now when i go to thrift shops i grab cheaply priced electronics kind of hoping they need to be fixed so i can try it, and if there not i still open them up for a good cleaning.
tbh their's not much to go wrong in a basic walkman, removing and replacing all the damaged belts, cleaning with IPA, replacing all the lubricants, removing any battery or capacitor corrosion, and at worst replacing the capacitors. This should be a fascinating series of videos :D
for someone who do not no how to fix things at first is one good handy man keep up good video's vince well done
I had found my old walkman and tried a repair after seeing your video. He works now again so good as I bought it 1991 :)
@mymatevince: when you’re soldering wires in tight places, try soldering on a longer wire first. Only then, cut it to size after you’ve measured the length required plus a little bit extra in order to strip the insulation.
FLUX..FLUX..FLUX never too much flux.YOu never use enough flux and the joint goes dry. Watch Louis Rossman to learn how to do this type of solder work and remember his sage advice concerning flux..."The bigger the Gob,The better the job!"
Don't open the others like that, Sony usually gives clues on how to open their products.
If you open the cassette door you'll probably see half a dozen arrows pointing to slots. Cut some shims from a pop bottle and push them into the slots to release the clips without breaking them.
Plus use blue plastic spudger
@@XtremeKremaTor Plastic on plastic, alloy on alloy.
That's why it's quite obvious why most of us got through the 'repair' and do it successfully.
Great job!
Some of these (including the one you worked on here) actually were made by the Aiwa company that Sony took over 20 years ago. They recently stopped using the name as they thought it was competing with their own brand and had a slightly lower reputation from selling all-in-one stereo systems..
I have had a few Aiwa models that also recorded in stereo, and an original JVC from the very early 80s that also recorded in stereo and is still my favorite.
The rubber belts are synthetic rubber that turns to goo if left unused for long periods. This issue goes back to the very first cassette units from Philips back in the early 60s. They had the same problem. Real rubber tends to stretch and dry out. If it is just stretched and dry you can renew it by boiling it in water in a microwave oven for 6 to 10 minutes. It will shrink back to its original size and be re-moisturized. It will usually last a few years after that.
Solder-covered traces: This is usually done to increase current carrying capacity or heat dissipation. Thin traces may fail under current draw so solder increases the thickness and current capacity.
Brilliant tips and advice. Thanks for sharing them :-)
Bloody hell you've done it again 😌 Fantastic repair video!
Thanks :-)
Thanks for doing a walkman video ,nearly 30 years since I had one
Hi Vince. Just wanted to say thank you for all the videos you've posted. You've inspired me to fix some of my kids toys, and using all your techniques, I managed to fix my first one today! It was a shape-sorter which has lights in it, but it started misbehaving, some not lighting up, or just staying "stuck". It's a somewhat poor design flaw (for 6m+ babies), as it has no liquid ingress protection and saliva had fallen straight onto a push-button pad corroding it, causing it to misbehave. A bit of IPA, followed up by surrounding the rubber button with vaseline should hopefully prevent any future corrosion inside the push button area. Anyway, thanks again for all the vids, much appreciated, and hopefully your videos inspire more people to self-diagnose and repair!
Dude I'm not working in my job because i'm addicted of your videos! :)
Sad times when something from my youth is classed as vintage.........................
I’m hoping to get a Walkman wm-2011 and I was trying to find a review of the product itself but instead I came across this video. Even though this wasn’t what I was looking for, I find this very interesting. I really enjoyed this video.
Belt changing is an art,Vince, I’ve changed lots in my experience and very few are spot on first time
Tape mechanisms can be really finicky and need a lot of tlc.you have a nice little collection there to work through.
Awesome work. Everytime a pleasure to watch your Videos.
Thanks :-)
Whoa what a strange coincidence, I just bought a Sony Walkman today. The NW-45 Series. Don't worry it isn't faulty lol. Can't wait to watch this video!
Nicely done very well worked out.
This was very interesting. I’m 19 so I grow up with the iPod and Spotify 😂
NICE! i recently bought a walkman and replaced belts. collecting tapes, looking forward to the next videos
You are an inspiration. I started trying to fix things around the house now haha.
Excellent :-)
Great video again mate. Top stuff.
great job . Soldering skills are really good. a pro could not made it look much better so well done. You avoided messing it up with bridges in a tight space. 10/10 for that.
Thank you :-)
Should keep one of them if you ever get an old Spectrum, ZX81, ZX80 computers in your repair escapades. Excellent vid as always and always an enjoyment watching you go thru the steps bit by bit and no corners cut :)
Good video Vince. Nice troubleshooting . Love watching your vids, greetings from across the pond. 👍
looking forward to watching this video i remember i had a sony walkman thin one silver and it went wrong so tried to take it apart but had no idea what i was doing so it didn't go back together right and ended up in the bin, i was only 12 or so.
Good patient work!
I have a Sony Walkman with a metal case and nice fix vince can't wait for the other ones
Wow, great fix on this vintage walkman.
There was nothing like a Sony back then, I remember in my 16's owning one just slightly bigger then a cassette with a rechargable powerpack that clicked on the small side of it, for those days it was tiny.
After that I changed to Diskman and even after that to portable minidisk player.
Love this video.
I heard from audiophile that aiwa had best sound quality and sony were make with better quality manufactured and durability!! Even we can see that this walkman fixed in this video had more than 20 years and just it was replaced the belt and follow working!!
Thank you so much i finally fixed my dads walkman because i never listened to old cassettes music
@ 01:19 that's the one I had about 28 years ago. It cost £90 from Argos at the time.
32:00 Absolute class moment :-) It's so nice to see I am not the only one who has these things happen to them .. except, you swore less than I certainly would have done. Well done for keeping posure ... and, nice video .. enjoyed it ...
You earned 600 skills points by fixing this Walkman. Be proud.
Amazing fix, used to love these in eighties :-)
Thank you :-)
I had the first one,Oh such memories,Nice one Vince
The dictaphone I had at work many years ago was mono(single headphone)
Nice job, had the same problem with a walkman just had too put in new rubber bands, if you have the right ones it works perfect.
when the board snapped i thought it was all over lol..... well done.
Another great vid Vince compulsive viewing.
Wow Vince that was like microsurgery. I fix walkmans, tape deck and four track portastudios. And I have come across similar problems with cracked boards. Well done dear friend. Kind regards. Paul.
Great fix on video as always
that walkman is £20-35. fully working. thats insane. if you can get them all working theres a massive profit to be had if you sell them. Nice job
I have a WM-AF23, which is a Variation of the WM-2011 (from what I can tell sometime in the mid 90s, perhaps 96). Same problem after accidentally dropping mine. Good to see it isn't the end of the world
I loved this, I remember having one and what I would give to have one again lol if you ever sell them please let us know would love a chance at one. Great vid
Great job keep up the great work
Thanks mate :-)
Recently discovered your channel and love what you do.
Hope you go back to doing more computer and/or console and their associating peripheral fixes. Bonus points for Commodore related products (e.g. Amiga)
As someone who has worked with electronics, I can recommend that if you're doing this sort of thing, it really is worth investing in some smaller tips for your iron. Also, not sure on spelling, but kinar wire is what my mum and dad always swear by for tiny track jump repairs. It's really fine and wouldn't have got in the way of that plastic bit. Just suggestions of course! Brilliant fault finding though! Loved the video. :)
This video was awesome. chasing a phantom fault lol. loved it. made me laugh, but then nearly cry as it snapped the pcb =( who'd have expected such emotions from a repair job of some old tech!
Bane of cassette users, rubber rot. I've got a Speccy+2 I need to get a band for sometime, you've just reminded me about it, cheers Vince.
Nice,I have the sony WM-BF44 and waiting forward to see it fix it.maybe i fix mine too
Man I had some of them, I love how you had to explain what they are haha
Great video.
I have one of these models and they're really good
For what it's worth over two years after you uploaded this video, I personally think 'bodge wires' are fine here, but I would have done some sort of reinforcing of the PCB where the crack is, to stop it travelling up the board over time and causing problems elsewhere. Epoxy or maybe hot snot or something similar would probably suffice.
Link to the band pack? And yes I am screaming.. Sometimes but you do excellent work, to not know what you do. It's enough with the solder you do not need the wires. And you only need to cover the crack.. Use some nail polish to cover the copper not covered with solder. For rigidity use some glue on the crack in the board. And if you want some better conducting solder buy one with a bit of silver in it for these type of joints. And audio quality. But nice repair I am impressed.
Thanks for the tips. The band pack is like these ones www.ebay.co.uk/sch/i.html?_from=R40&_nkw=100Pcs+Mix+Rubber+Pulley+Drive+Belts+Cd+Dvd+Cassette+Tape+Recorder+40+135Mm&_sacat=0&_sop=15
I bought them quite a while ago and I can't remember if I bought 2 packs of 50 or one pack of 100 and they sent 2 packs of 50 :-)
Great video again Vince well done i never had Sony ones Bush i think i had, for jumper wires i believe theres enameld wire ive seen Andrew Paul using it a few times to do jumper wires unsure of the cost though, miss the good old days with tapes im waiting for the betamax player repair ha
I love collecting cassette plaers, especially the units from Sony and Aiwa. Even low end models yield pretty good result.
My Mate VINCE... My man!!!!!
Next walkman fix use a 3v wall charger plugged into the walkmans power jack... It will save you from putting the case on with batteries... Will save you time!!
i love these series, vince please invest in a fairly cheap telescope fo r this sort of work, it will make it much easier for you, and much clearer for the audience, plus you could then possibly fix things you couldnt of fixed otherwise.,
I was thinking the very same thing he could buy a trinocula telescope with camera for under £400. He would be well away then and especially after all the great videos he's done I think he should treat himself.
Nice! I recently did a repair on a WM-2015, which is a little different.
Go on have another piece of toast ...that man on the tape was living on the edge 😂....Awesome fixit video vince mate 👍😀
Nice fix Vince... Little tip, Use some Blu-Tac to hold things out of the way or to hold things in place for soldering :)
Hi Vince, i have a tip for that's little bridges, i use old IDE Flex cables from old computers, they are thin enough and make a really good connection. Nice fix.
nice fix vince, that crack was hiding big time. Noce spot
There’s certainly a break in the the tracks now 😂😂😂
Maybe some epoxy to fix the cracks and solder to bridge the broken traces would work. Keep up the good work! Love the videos.
Nice fix :)
Love content like this
You should consider getting a TS-100 soldering iron with the small SMD tip and a LiPo Battery pack with xt60 adapter cable. This is very handy for such small soldering jobs. Also consider gerring a lot of 30AWG silicone cable. This will not melt the isolation while soldering.
I have the WM-2013, which is identical to the WM-2011, the only difference being the inclusion of a Dolby B noise reduction circuit. I bought it from a person, who wanted to throw in the bin. It came with the original box,headphones, manual and receit. According to the receit, my Walkman was bought in 1992. It works prefectly and I didn't have to replace any belts.
Fun Fact there are four different types of cassette tapes There is Type 1: Ferric Tape Type 2 : Chrome Tape Type 3 : Ferro Chromium And Type 4 : Metal Tape The Best Sounding Cassette Tape :-)
Nice info, thanks for sharing :-)
@@Mymatevince Of course Your Welcome Your viewer - Mate Brian :-)
Although Ferro Chrome was a short lived experiment which basically left the 3 tape types most of us knew-Ferro,Chrome and Metal
@@depechem0demusic Correct !!! I still thought it was worth metioning :-)
How come not Techmoan's making this comment? :)
As always, love the videos! ...but who else thought that Vince said “fart finding”...
Thanks for video! just fix my Sony Walkman WM-BF28 have to change only the Belt and works like a new :)
Next time use a smaller tip on the soldering iron and remove the insulation on the jumper wire and just put it ON the track, not as an arc above it... make it part of the track by pushing it down and adding solder to the track over the bridge wire... but definitely don't add that much solder :)) I really admire your determination and patience, keep up the good work :)
Nice fix. I had only one walkman type cassette player, think I got it as a Christmas present in 1989 or 1990 but it wasn't Sony Walkman. Sadly it got lost during the years.
Fixed myself one cracked board from old 80's Salora Manager computer joystic by adding solder over the crack. I really am not very experienced at fixing electronics so not sure how long lasting fix it is but I'm not even using it much so perhaps it's ok in this case. Failing that I could add some copper wire or even jump wire there like you did in the Walkman board.
sorry for the spam but really awesome video and was very happy to see it working
5:53 this is what I came for. And that 6:19 with this 6:41 is exactly my problem.
When I grabbed it for free, I popped in a Phil Collins "But seriously" cassette, which has great studio mix and therefore is great for making a sound check, but this thing ate it. :( I was shocked! Rolled the tape back in (and hopefully it isn't ruined) and gave it another try, with another less important cassette. It played and I used rewind, but noticed how it often slowed down while rewinding. Fast forward was not possible at that time. When it was done rewinding, the cassette player was done as well and the issue above appeared. Fingers crossed that it's really the belt.
Well, the belt came off. I used an adapter to power it up. Head was spinning, but after putting the rubber band back on, it was dead. Competely dead. Well, gonna turn it into a dummy, by just using the case. Sounds funny, but I need it for reasons.
Sorry, I had to laugh when you snapped that board, so glad you fixed it in the end.
i deeply enjoy your process, so far have not had any problem with the things you've chosen to repair.
speaking of repairs... any update on the "My Mate Vince vs Tronics Fix 2019 repair challenge"?
Nice!
I remember that model. the model b4 that used screws. the belts just dried up in those most of the time.
Replacing rubber belts might introduce speed variations. I think i saw a potentiometer with which you could adjust the speed of the motor. You'd need a tape recorded on a reliable tape recorder with the correct speed. Put a 1kHz tone onto the tape and measure if the walkman plays it back with that 1 kHz recorded. That might need an oscilloscope tho ^^; or some other way to measure frequencies reliably. Maybe even feeding the audio signal into your PC and getting it measured there might work. I'm pretty sure there's programs like that. But that's only if you really care about accurate audio reproduction, speed wise. Audio tapes (normal, CrO², Metal) have different audio characteristics. The little switch you saw applies an equalizer (Audio filter)to compensate for that.
Epoxy is a good idea for the broken pcb board and it would not hurt to use uv conformal mask over the solder joints.
The belts really do need to be the right size its important on a cassette deck if its to tight not only do you put stress on the capstan motor but all the other moving parts, also a tight belt will give you a lot more wow and flutter most notably a humming which you will hear through the headphones as the motor has to work harder.
I am 14 and I have loved walkmans 😁
You gained my like at the 31:59 mark. Well done mate. HAHAHAHA
Hi Vince, love the majority of your videos, even those where you can't fix an item. Just an fyi, that tape is of the BBC long running radio soap "The Archers"
Thanks for confirming. When it said "Archer" during the video I did wonder but I have never listened to The Archers so I wasn't really sure. I thought it might have been some soft erotic tape when it mentioned the bum in cords at the end :-)
My Mate VINCE my late mum used to listen to the Archers Omnibus every Sunday morning while she prepared lunch, the voices were unmistakable
To fix broken traces. I would personally use the leg of a resistor or capacitor to bridge the crack. Tin the leg up good and make a 90 degree bend tin both sides of the crack and then lay the leg across. Then solder in place and cut the 90 degree bend off with flush cutters. The 90 degree bend is good for holding in position while soldering.
Nice tips :-)
I have the WM-EX21 which looks the same as the one in the intro that is immediately to the left of the one you repaired in this video. I use it with some Metal Tapes that I recorded with a Cassette Deck
I love the channel Vince. I would love to hear of what you do for a living? I recall you said you used to be a telephone engineer, is TH-cam your full time occupation now?
Hi Vince, I'm a long-term subscriber and I watch most of your videos, even the really long ones!
Just a suggestion, not criticism, but if you look on amazon or ebay you can get some Rosin Flux Paste, it makes a world of difference, you just use a small paintbrush or toothpick (if it's a wire that needs tinning, I just dip the threaded wire in the paste after twisting the threads together) the solder sticks to it and stops balling up or pooling everywhere, I'd been soldering without for years, but using the paste makes things so much easier. It helps threaded wires absorb the solder via capillary action and gives a nice solid joint. I use 0.3-0.8mm 63/37 leaded solder, I can't stand the lead free stuff, it just doesn't flow properly and seems to take longer to melt and then solidify and all solder joints look like "cold solder" joints.
Keep up the great videos, looking forward to the next one!
Thanks mate for the advice, views-especially the long ones :-) and the sub. I appreciate it :-)
@@Mymatevince I forgot I was using this account, I subbed you with my other ages ago, it's just my PC and my TV use different google accounts!
Hi love ur vids
When you've got faults like this contact thing you found first, you put the meter into continuity mode and try to find where the continuity problem is and don't start bending an almost 20 years old board.... EEHHH!!! Vince!!! I would have just reflowed the joints anyway first.... (I'm still watching so I don't know if you solved it at the end :D)
I always used to mess around with the tape function and buttons on my old Walkman and cassette players for a laugh speeding up and slowing the voice down on them.
Just a couple of tips. First, get a bench power supply so you don't have to keep putting things together just to get the batteries to work. Second, get yourself a roll of enameled magnet wire - the insulation is extremely thin and can just be "burned" off with the soldering iron. The other comments about using plastic pry tools are right on, too - try getting a phone repair kit, as they have a lot of useful tools like that.
