Your video will help me replace my belt. Thank you for your sharing!
No worries! Glad it helped you out ☺
I recently got this model yet working perfectly, but yesterday the belt broke apart. Your video saved me, specially to be careful with the thin wires when I was replacing the belt. Thanks.
No worries! I'm pleased you found the video useful! I've got a few more I need to repair
Thank you for your sharing.
No worries at all! :)
Thank you for making this! I thought I'd have to figure it out by myself
No worries! Hopefully it will help you with getting yours fixed up. They can be tricky to work on
I bought a broken one off eBay. It had horrible battery corrosion on both boards, missing PCB traces etc. I removed all the wires, scrubbed the boards with some sulfuric acid to remove all the corrosion, soldered in patch wires for the missing PCB traces, and resoldered all the wires and it actually works!
Yeah the old problem of batteries. That would have taken a fair bit of work as they're small devices. Does it work alright? Sometimes I repair them to find the pinch rollers are worn out and they chew tapes
@@thesmokingcap I just ordered some belts, so all I’ve been able to test is radio thus far. All levers and motors seem to be actuating / spinning well though
@@thesmokingcap I got mine almost perfect now, but the auto-stop keeps triggering so I have to hold the play button. Oddly it works fine if I stand it on it's right side
@@Collinormous @Collin Ahhh yes, I know the problem. There is a little spring that keeps the auto stop mechanism from randomly triggering. I have another video fixing a WM-F65 that covers what part is causing the issue. I will link it for you. If you go to 9:35 this part is the same on the WM-F15 and could be the issue if the retaining spring is broken. czcams.com/video/Ua7nPKzOU1M/video.html
@@Collinormous Also to add, re that video. If the spring is still on the assembly, it will still flop about as shown. But it should spring back when pushed diagonally. If it pushes in but doesn't sort of spring back, the spring is broken and the little plastic arm isn't being held to the outside of the plastic circle around the capstan shaft. Hope that give you a direction to check! I have another one to fix so will cover this in more detail on the next one I repair.
I had the headphone jack with green surround fail on my WM-F41. I ended up geting an entirely new jack from radio shack with a tiny metal lock-ring, about 2mm tall, and replacing the jack entirely. Now that there is an external, steel 2mm lock-ring, inserting the plug puts zero pressure on the printed circuit board inside. It should last forever! This was a design shortcut on SONY walkmans and a design mistake, imho, you should never mount a banana plug adapter to a circuit board with the solder connections alone!
Ahhh yes, nice little mod. ANd yes it doesn't help these are quite old and the joints can be weak.
I can see you cleaned off a tarred belt previously on this unit - I imagine the wow is from some residue still left on the pulleys
Humm yeah that stuff is hard to clean off. I need to try the WD-40 trick to see if that helps. I have another one I need to fix
@@thesmokingcap If you can somehow get the pulley out, acetone will dissolve almost anything, including paint, rubber, etc., to get a completely cleaned-up pulley.
@@dgillies5420 Yeah I have heard that acetone works. There was some small plastic gears under the pully so didn't want to use anything too strong
hi I have two and both are not powering up. what should i look for? i took the back off and see where the battery contact terminals touch the + and - on the circuit board. They're touching fine but I can't figure out about the power. Thanks
Hey there. Sorry for the slow reply. Does the FM radio work? If so that means it's getting power. I would then start looking for bad connections, often the small wires come loose
My mom gave me hers but the cassette part on it doesn't work I'm hoping this video will help
Mine won't even spin
Nice gift! Hopefully the video helps, checking belts is always the first one. Also if the radio works to at least see if there's power to the unit. Everything else is pretty much down to broken wires really
Nice fix, fiddly work for sure.
I wouldn't recommend these as a hobby haha
@@thesmokingcap too late, I’ve got a box full of them that need repairing 😅
i have been following your videos with great attention. I have this beautiful Sony Walkman in red and I need to repair it. Could you please tell me how do you make the battery case and where do you find the correct tips ? I know that the Sony tips are negative in and positive out and I don't want to use one of the 3V universal chargers from Amazon I do not want to destroy the Walkman; If you could make a video that would be fantastic for a lot of people ! Thank you so much for your videos and your help.

Hey there, Glad you enjoyed the video! For the battery holder, it's just a generic double AA holder you can find from any electronics store. I used a generic tip as well that you can solder the wires to. I believe Sony have made a external holder that carry's 2x C cell batteries. You can find those generic holders at any electronic stores
Thanks to this video, i replaced the belt on my Sony unit. After putting it back together and press play, there is an audible clicking noise. It can be heard on the side of the tuner wheel. If I loosen the screws on that side, it goes away. If i press down on that side, it comes back. I tighten the screws, it comes back.
I assume it hits something when play is pressed, not sure what it could be though.
Any ideas?
Nice! good to hear the video was of some help for you. Apart from checking the hub teeth for bits of dirt. My best solution would be to remove the front door and bezel. Then just screw in only the back cover for the battery. (unless you have an external power supply). Run the unit without the covers and hopefully it will narrow down the issue. It could be a wire or something else rubbing. If it's not bits of dirt stuck in the hub teeth. hope that helps!
@@thesmokingcap thanks. What do you recommend for a power source? Primarily, the barrel plug
Do you know of any person or company that makes or sells the battery cover for this model
I wish I did. Perhaps someone could 3D print one? But apart from buying a damaged one online I'm not sure where you would find them.
nice little video, wondered how you cleaned scratchy noise coming from the volume knob, also to fix the connectivity of headphone jack sometimes only one side of audio output
Unfortunately that was apart of the video that I forgot to press record on. You unscrew the little screw on the volume wheel, then put some Deoxit or other electronics cleaner inside the volume pot wheel and give it a few turns
@@thesmokingcap by the way, what do you think about the sound quality with this model?
@@lenco5994 There are better Walkman's out there. But if adjusted and not completely worn out, these are pretty decent.
👍👍👍
the belt keeps on coming off, is it because it can’t be twisted?
Could be a belt size issue, where did you get your belt from? Also are you missing the main capstan shaft retaining washer? It can cause the pulley to move and the belt to come off
13:58 this crap always happens to me every time I'm speaking at the phone or explaining some really important. This is a curse. BTW great vid.
haha, yeppp. I live under a flight path so comes with the territory. I don't notice sometimes until I'm editing the video. Also thanks! :)
Great video Thanks! I have a WM-F15 since new. It hasn't been used for years but I'd really like to get it working again. The radio works fine but the cassette tape pully doesn't roll. I replaced the belt but that hasn't helped. If there's anything else you can think of that might be causing the tape not to work I'd really appreciate your input. Thanks again :-)
No worries, glad it helped! Is the tape transport moving at all? Is there a way you can power it up without the back cover on to check the motor? Like using an external power adapter or battery pack like I did
How do you open the black cap on the back?
For the speed adjustment? If so, you can use a very small screwdriver to push on the back side of it, once you remove the back cover
@@thesmokingcap I tried doing it with those Jewerly screwdrivers and I don’t really know how to do it
Hello. I have Sony WM-F 65 . I have problem with playback cassette. When it playing, heard a loud motor sound. When it plays radio clear sound. I suppose some wires problem, but I’m not sure. Maybe someone know what it could be? Thank you for any advise.
Is it like a loud humming sound? If you stop the tape turning with your finger does it change pitch? I've had this before as it's usually a bad ground, or some of the capacitors are getting tired and are not filtering power as they used to
@@thesmokingcap I will check. If it some of capacitors bad, same problem with sound when radio play? Thank you for advice.👍
@@artzauyer344 no worries and good luck! These things a picky little devices mixed with age. There’s a service manual in the description if needed as well
The left gear on mine gets stuck
Ahh yep, you might have a cracked hub gear. I think my WM-F65 video covered this issue as well. As they're practically the same unit. Seems to be a common issue now on these units
Nevermind I fixed it today :3
I repaired mine , i put a new belt in, plays good, but once in a while when playing, the playing button pops out, can you please help?.
Nice! Yeah I've had that before. Behind the capstan shaft is a little plastic hook. This falls into a grove when the tape stops moving and clicks the player off. There is a tiny spring that you can't see, that often breaks. So my fix for this is to use side cutters to take the little plastic arm off. I'm repairing another walkman with this issue so can go into more detail for you. Hope that helps somewhat!
@@thesmokingcap i hope you make a video of it thanks.....
@@frankienebula No worries and stay tuned 😊
@@frankienebula Hey, I've uploaded my other video. You're issue might be at 9:40, that plastic pin rides into the capstan shaft gearing. Check to see if your little spring is still in the head assembly. Be warned, it's not easy to get into!
Just had mine apart today with bad battery corrosion. I've had it since it was new in the 80's but stored it with batteries at some point unfortunately. The belt is melted on the rollers and the board has corrosion inside it. Any tips on cleaning the belt goo? I was really hoping I would not have to take it apart completely.
Wow! From new! What year did you get it? I think they started production in 85, but not sure how long they ran it for. I've heard that WD-40 works well on sticky belt goo. You can put a little on a cotton bud after removing most of it with a small flathead screwdriver. Then followup with alcohol to remove the WD-40 and last of the belt, hope that helps!
@@thesmokingcap Thanks I will try that maybe this weekend when I have more time. It was probably bought around 1985. I still have the manual which is just a folded piece of large paper and has copyright of 1984. Also the Cx20085 chip on the board looks like it has a date code of 8435 which would be 35th week of 84 if that's what it means. Watching your F65 video now..wish I had watched these about 4 hours ago before I tore mine apart and then put it back together defeated.
@@androskris Hopefully it works out, just don't spray the WD-40 in there haha. Wow! you've had it a long time. I would have loved to have brought one brand new. Hopefully those tips help and you can get away with just doing a basic service. It can be done!
Great video! I've got all the screws out on the bottom and back, but the board doesn't want to push/jiggle out like you showed in the video. Any tips? I don't want to pull wires off or further mess up a non-playing player. Thanks in advance!
nevermind i got it hehe
All good. Glad to hear you got there. They can be fiddly to get out
@@thesmokingcap Very fiddly, though it's still a bit awkward because the wires on the right side of the board are tight/short and I'm not able to get them too far out of the way. But I have the board propped up with a small screwdriver and it seems to work. The belt was melted, so I've ordered a new one. Had to spend a long time removing the molten belt from the wheels, but it should be ready to install. Thanks for the reference for that process, too!
@@trainyardhero Oh no! sticky belts are never fun. These are also quite hard to work on when that happens. You can try some WD-40 on a q-tip and see if that breaks down the goo. And followup with some IPA
@@thesmokingcap Thanks for the advice! So I've got the new belt on and it does now move! The problem then is putting a tape in and it not moving the spools of the tape (or it does for a second and transport stops). Some tape then gets pulled out of the shell as if it is going to be eaten. Play pops back and the player stops. Any suggestions? Is this a deeper issue than the belt then? Thanks for all the help
