- Hi, this is the 4th video in the Sony Walkman series. In this one I try and repair a faulty Walkman WM-FX10 which is noisy and has vibrations.
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.
I couldn’t help laughing at the result after putting oil directly in the motor and then assembling the unit and playing the cassette.
Vince, TronicsFix, Louis Rossman... These channels are one of the few things that seems to relax me at this point in my life. Watching someone take a broken item, troubleshoot it, and then fix it in various ways gives me a really good sense of satisfaction somehow.
Keep buying broken things to fix, and I'll keep watching!
I don't think it's your age that's the problem, but the age we live in.
If you like electronics and relaxing watch Big Clive and listen to his soothing voice.

DiodeGoneWild too.
Hearing these two people over and over again on the casette arguing makes me wanna buy this casette and listen to what they are actually talking about 😅 great video!
Love the vid. I used to repair boomboxes and tape decks and in the 80% motors were trashed. Noise was not always the issue but speed stability. When this motors have long play hours the brushes start to worn out. This produces a change in the motor internal resistance that the speed controller is trying to compensate to adjust the speed. Once the internal resistance starts show variations, motors are done because the speed controller cant compensate or it falls outside the adjust range. YOU CAN lube the motor. Most of the stress is taken by the exposed bearing, it is made out of bronze but it is like spongy structure, they are supossed to be "self lubed and maintenance free". Well, you can help the situation using a very fine oil and spray the bushing. The rest of the noise can be, the internal bushing or the brushes that are badly worn out. In any case, the walkman of the vid play perfect. This is the only thing that counts. Belts are CRITICAL in walkmans to stabilize the speed. Walkmans have POOR W&F figures since they tend to use plastic flywheel, with NO WEIGHT AT ALL. How the managed to make thing work ?. The speed controller is fast enough to react and compensate instant variations produced by the clutches and iddlers. They perfected this so much that a big flywheel was not longer needed. In mid 70, A proper tank from AKAI had WORSE figures in W&F that JVC-KD-X series using a boombox type mechanism that was almost a toy. Speed controller had improved a lot in 10 years
Great information, thanks for sharing your knowledge on here :-)
@@Mymatevince Keep with the vids, love them !!!!
I have fixed some of these clip-on-case plastic-save-production-costs-to-the-max walkmans, most of the problem is the flexibiity of the plastic and the age of the plastic. I had one that scratched one of the wheels against the case when using a little force or change orientation. Could be result of temperature, environment, properties of the plastic has changed/stretched over time.
At another one the belt was perished, so need another belt. Always replace the belt, it was clearly to see you need to change the belt. And when you do this clean everything and lubricate where necessary, including the spindle/rotor of the motor. Do this when everything of the mechanism is operating, you wil get better results, you can hear the difference. Spindle/rotor of the motor the same, use aerosol with silicone oil. Also works great with noisy laptop/computer fans. Clean any spill afterwards.
When you still get a high noticable wow and flutter (wobbling sound), remember that the age of the plastic (most of it is made out of plastic) and there is no weight (iron) attached to the flywheels to compensate fluctuations or to stabilize speed. I added some bolt rings (with use of striong slow drying glue and center it in the middle when spinning and align it on the outside of the ring with a screwdriver on fixed position) to the flywheels. Let it dry and try agian. Difference is remarkable, only just a few grams will help to get a better constant speed.
These walkmans are made to a maximum revenue price point, they can be pretty good however depends on condition, usage and environment influences. There are a lot things that can go wrong, it is not the electronics, it is the quality of plastics they have used and that most of the unit is made out of this.
Here i was looking 5 minutes into goggle and found the Motors they cost 1.65 Pounds each. well depending on where you buy it hope it helps. www.ebay.co.uk/itm/1Pcs-Mini-motor-RF-500TB-14415-RF-500TB-14415-3v-12v-DC-motor-RAHN/153198572551?hash=item23ab58b407:g:qy8AAOSwUKhbn3Cy:rk:2:pf:1
From what i saw they are avalible in diffrent specs so you might take messurements first :) The name to find them on ebay is CL-RF500TB
Thanks for the link :-)
Also, parts of the mechanism can make noises in certain positions. Be sure any mechanism rotating parts are oiled (those with bearings) and especially the capstan shafts. (The shafts the big wheels inside turn.) Other parts may have worn loose. They are not replaceable. Some can be fixed with tiny washers and other tricks. I have even drilled them out and inserted tiny bearings made from brass tubing or salvaged from junk mechanisms.
"Would be interesting to have a look in there wouldn't it" - YES, TAKE IT APART! Love the vids Vince
Didn't know that Sony made Diesel Walkmans back in the days.
Why not use one of these for the oil. 10Pcs 30ML Rosin Bottle Dispenser For Solder Flux Paste with 11 Needles Tips
Great video and content!
Is it only me that loves the sound of plastic and metal clicking!?
YOU NEED A SMAL SURENGE TO APPLY THE OIL THE REALY SMALL NEEDLES ARE GREAT FOR OILING SOMETHING LIKE THAT.
Oil it with CRC 2-26 or any light lubricant that is good for electrical stuff and then mostly the problem of noisy or badly running motors will be solved.
Make sure to get it in both ends and so it can work into the bearings and the commutator and brushes.The light oil and some plastic grease can be used carefully on other parts of the Walkman too.
This is a good fix for motors in CD and DVD players also because often the motor will get stiff sluggish and the disk won't run up to speed.
Nothing to loose for a try anyhow..
Let's call those bands, RBB's Rubber Belt Bands. Then everyone's happy :) RBB's
for a noisy motor use some sewing machine oil inside it. it will help.
tip, To hear noise don't try to put to your ear, use a long screwdriver , put the blade to what you think may be causing noise, then block your ear with the handle.
You should do a Sony Walkman CD players next
Hi, I ordered up 5 broken ones a couple of weeks ago so hopefully I will get to look at them in March :-)
Oooo I'm excited for that :-)
Discman.
Another nice video! Really enjoying this "walkman" series!! Good job on this one, but there's still horrible wow & flutter on playback of the piano track......but that could be linked to the suspect motor still ;-) Looking forward to the next in this series :-)
Heck yeah!!! I’ve been waiting for this!
Hey Vince, for 400K you should do an outtakes/bloopers video. XD
Mark Santos I’d love to hear him cuss once haha
I repaired a Kenwood KX-520 Tapedeck where pretty much everything was misaligned, parts bent, all transistors pretty much close to "I better change that. right and left channel's hfe aren'T even close...", but it had one thing going for it, a motor you could take apart completely. After I cleaned and lubed everything and put things back together again, the motor was actually running way too fast, free'd from all the dried in grease and dirt. I guess that meant "success". I really like those old devices that were still meant to be serviced ^_^
It is common for a unit that has been sitting for decades the bearings are probably dry. A needle oiler can be carefully slid under the pulley and a drop applied. Sometimes it brings them back. Clean the pulley off afterward. The internal bearing often survives because it is not exposed to the air. When that doesn't work a new motor is indicated.
Universal motors are available from several electronics parts houses. Try www.alibaba.com/showroom/cassette-player-motor.html for a start.
Thanks for the link and the great advice on both comments :-)
Hey Vince! I want to know if the Joy cons that have the drifting problem is still working fine or not after you sprayed it.
ebay have a lot of 3vdc electric motors. Not sure of the dimensions of the one you need but there are a lot to choose from and cheap too. Keep up the good work Vince.
I didn't realise they were so readily available. I was typing up 'Sony Walkman motors' and getting no where. At least I know if the other 4 in the series have bad motors that they can be fixed cheaply. I just need to check size and voltage, not sure if RPM comes into it or not so it is something I may need to look into :-)
The metal strip around the motor is probably a magnetic shield made of heat treated mumetal.
This flexible steel thing around the motor is a shield. Without it the motor could interfere with the audio circuits. This walkman is not bad at all. I had one. It does not get slower and slower as the battery is being used. It maintains smooth speed and then cuts out when there is not enough power.
Took me thirty years to realize ... fixed mine a month ago and play cassettes over and over now ... and then - all of a sudden - it happened - just cutted out 😅 !!!
Can anyone help.Sony tcm323motor speed adjustment
Yo tengo el mismo modelo, lo revise y tiene la liga gastada, pero el mecanismo de cassette no gira, que creen que sea?
There seems to be quite a few of these that have an inline remote control but will only work with the matching inline control cable.
Put your head phones on and you will not hear it :)
Mine stops spinning over I push the button all the way down
pry the pulley off with a screwdriver then your able to get to the bearing
I have the same device, only you don't hear what I do, it helps
a few pounds hay you hear about the vcr who got killed for her mothers ? hahhahhaha cheep to free hahha
for what it is i would say its fine compared to at the start so its a success in my opinion
Hey wow, it took some time to get to this video ! Been looking forward to a new video !! Thanks !!
Whack it on eBay anyone will pay £200 for a pile or crap.
first, subscribed and tapped bell
Thanks, needed it.
SuperGamerHD you are first
U speak a lot which is really not needed every time
Pray for Emiliano Sala 🙏❤️
What do you think about the Sanyo M1118?
What music is that playing in Tape plzz
Awesome job again! I am glad you tried oiling the motor - I've got loads of questionable motors working that way before.
Thanks Chris, I wasn't sure if it would damage it or not. I need to see if I can buy a tiny little oil dropper as it would useful on old clocks/watches as well. I got a bunch of faulty Walkman CDs as well, I'm thinking that in your fixing history you must have fixed some of them before :-)
Its the cassette tape making that clicking sound!
I already opened those kinds of motors and transplant brushes and the coils. It works after all. You don't touch those plastic dots, just undo the edges.
Where do you source the belts from ? I was thinking about getting a Walkman from the 80's
I got them from eBay :-)
the motors on these later devices are really damn annoying :/ For a lot of the tube motors like on the TPS-L2/WM-3 the motor can easily be disassembled to clean and lubricate. These however are sealed shut, tried dismantling one a while back to no avail. Clearly reparability and maintenance was not really a priority over at Sony at the time.
I'd suggest a drop or two of oil in the motor. Often helps.
That belt also looks to be very past it.
That shield on the motor is to prevent static noise ( interference) from going into the player head
Without it, a loud buzzing sound will be heard when the motor is spinning.
Hi, thanks for info on how to take apart i've had mine since new and just decided to use it again and NO DRIVE striped it and the belt has gone bad. Any idea where to get a new drive belt?
I loved this Walkman!
there always used to be noises from the cassettes, that clicking is probably that...?
How can you tell the year of your walkmans? I have a wm-ex182 i found a few days ago at my dads house. I think its mine but have no idea when I bought it. I'm going to open it up and get it going when some new bands and some longer screwdrivers come. Thanks for your videos, they come in handy.
Yay!
XD all these comments have one like
Shipstern YT you’re right😂 maybe it’s Vince lol
Wow I fluttered lol
So amazing the AM still working in UK. In my country, the AM just produced a noise, can't find any channel now.
Had this playing in the background so not sure if I missed it or not but. Did you try and clean and sand off the pinch roller rubber a bit? If the new belt is used, I would rub it with some sand paper too. It wouldn't hurt to give the gears a drop of oil in the center as well.
I have had a few experiences freeing up bad CPU fans with a little bit of mineral oil. Good luck.
i have a faulty xbox one controller i would love to send you,, my son tried charging it with a phone charger and fried something inside but when i try to turn it on, sometimes it lights up but very dim, im sure its something simple, i can send a pic of the board, theres a little white chip/component thats no longer connected via 1 of its legs/connection points but maybe its more than that and its beyond my understanding.
you definitely need to grab a variable bench power supply mate, save all your vids you struggling with batteries haha, good job!
Are you sure you cant take it appart? There were small tabs from the case holding the motor together, pull them away and the front should slide out and then you can see the coils within
Vince did you try looking on AliExpress for that motor? There could be a motor that would fit on there.
Guess who's back, back again, walkman's back, tell a friend.
why nhot use a power adapter instead of mucking about with batteries? ;P
Great video!!!!
I love the Sony Walkman series!!!
Great work again Vince, keep it up mate. :)
Thank you :-)
Cool
The regular click-click-click toward the end of the video is probably the tape itself as opposed to the Walkman. Those Hi-Tech tapes were cheap Hong Kong made cassettes of very poor quality. They're OK for testing but the mechanical parts in those tapes weren't made with any precision, to the point where most of them would jam and self-destruct after a couple of months of use even back in the day. You could hear the very noisy wind/rewind as well -- the tape often doesn't wind itself consistently around the hubs, so if you want to continue using the tape I'd play it back from start to finish (not rewind, use play) and this should keep it quiet.
Or, just buy a better blank tape. They're only a couple of quid new on eBay and will be a more reliable measure of speed, wow and flutter, sound quality etc.
Hi Vince were do you get your belts from l know on ebay what seller is good
The metal ring around the motor is made out of a special metal.. To prevent magnitizeum/electrical interference
Also I started a new TH-cam channel (Vinyl Selecter) all about vinyl.. Am hoping soon to repair audio equipment
The Speedwagon Foundation would be able to fix this easily
I love this series keep doing thanks
Thanks :-)
Has anyone found a source for Sony Walkman motors ?
Great video as always, Also make a face reveal video👍
Great job and video! Thanks!
Awesome video 👍🏻👍🏻👍🏻
Love footloose. Another great video
i do a similar trick to getting old seized hard drives going, it helps if you can isolate the motor to heat it up a little with a hair drier get it all expanded out so the new lubricant can penetrate as best it can throughout the motor.
Thanks. Interesting fix on the hard drives, that might come in handy in the future :-)
22:22 you gave the game away!
Blue soldering mat is Preciva 500. I have the same one!
Yaaah , Awesome vid mate
Thanks :-)
Great job Vince! Keep up the good work! Pretty soon you'll have to stop calling yourself an amateur!
Bearing in motors gone
There are two general types of motors. Motors with the coil on the spindle and the magnets around the outside. These require brushes(what you call probes in the video). The brushes are required to give the coil electricity by brushing against metal plates set in a circle around the spindle. Motors with brushes tend to be used with higher voltages or power. The other kind of motor has magnets on the spindle and a coil round the outside and doesn't require brushes as there is no gap to bridge to supply power to the coil. These kind of motors are used in low voltage and low power applications such as the tape decks. Another thing you call the variable resistor a potentiometer which it very well may be. The only difference to a variable resistor and a potentiometer is the setup. A variable resistor setup uses two contacts one of the outside contacts and the center contact which is called a wiper. These are connected in series(in line) with the part and alters the current to it. Potentiometers use all three contacts the outside two are connected to the power rails(the +V and the 0V) and the wiper(center connector) is connected to the part. This is called a parallel connection and alters the voltage to it.
Thanks again for the great info. I will try and remember to look for 2 or 3 contacts in future as I often come across potentiometers and variable resistors and I didn't know the difference :-)
@@MymatevinceThey will all have 3 contacts it's just that on a variable resistor setup one of the contacts will just go through a blank hole in the board or soldered to a copper pad which doesn't go anywhere. They don't actually physically remove the contact they just don't use it.
@@pds8475 Thanks for confirming :-)
the bearings on the motor are weared ... just put some lubricant there between the roller and top bearing it should be fine ;) You should not wiggle that much those parts be gentle you don't want to tear any wires. Also you don't have to drown whole mechanics in lubricant either the belt path - some gears require friction to work properly
Thanks for all of these amazing videos Vince!
That is definitely challenging, a motor problem
Josh McCellan no it’s not. DC motors are pretty cheap.
@@JZM006 no, I'm saying trying to fix a motor
Can you imagine see a person with a walkman at the gym or jogging. That would be hilarious. Its almost part of a halloween costume at this point.
You can thank me for this series for suggesting this 🤓👍
@The Sonic Team & Knuckuls why what ?
Your best bet for 1 or 2 3v small motors is probable AliExpress. Alibaba would certainly also have them but generally there you have to order in bulk. You can remove the pulley with a pair of needle nose pliers, it's best to gently heat the pulley/spindle with something like a hairdryer or heat gun on low as the metal expands making it easier to remove. Then use measuring calipers to measure the width of the spindle and order one with the same spindle diameter. Also a good idea to order a motor as close to the original height/diameter as you can get. They're dirt cheap on AliExpress, only a couple of pounds.
