as someone who replaced surface mount caps by the hundreds whenever I was recapping something 15 years ago, the easiest way to remove them is to not unsolder them, but to twist them off the board with some needle nose pliers. the legs of them are designed to break away. then just clean the pads off, apply new solder, and then set the new cap. if you get into a rhythm you can replace a cap every 30 seconds. unless you run into a cap that leaked all over the board and compromised the pad so when you removed the old cap it ripped the pad off with it. but even with doing a repair for that, it still is far easier to just twist the caps off than to try and unsolder them.
Fixed 2 of these Vince. It’s all the surface mount capacitors in the shielded metal box, plus many either side. Remove all surface mounted and replace with wire ended,fiddly, but possible. Once you’ve done that all should function as designed. When the capacitors go it increases the “Ripple current “ to ics and voltage becomes “unstable” to chips. This causes errors and erratic performance. As you mentioned,you could just replace the bad capacitors,but I always do all of them to “ future proof “ it, as surface mounted are prone to go,and you don’t want to have to revisit it in a few weeks,when a few more go bad. Good luck Love the videos keep it up👍👍
Don't assume the 0V side goes to negative, sometimes if there is a negative supply rail, the 0V rail will be the + side of the cap, in this case there is a white line marked on the PCB for the negative side of the cap.
There was a huge TV ad campaign for those Bose Wave Radios back in the 90's and 2000's here in the U.S. I saw when my neighbor across the street ordered one and it was delivered while they were away, and was left on their porch. The box that it was sent in had BOSE written all over it. I could easily read it from across the street at my house. Fortunately this was before porch pirates really became a big problem.
You can't always assume that the negative terminal will always connect to ground. If you had a product that used negative voltages the positive terminal of the capacitor would go to ground. There may also be designs where neither terminal goes to ground so its best to make notes of each cap or take a picture of the board. You also need to be careful regarding using higher voltage caps when using replacements. Slightly higher is acceptable too high can cause premature failure of a new cap as well.
Can you direct us to a source for learning more about overspecced capacitors? I can't find anything online that talks about replaced capacitors that are specced for a higher voltage failing prematurely.

I honestly like the smaller Bose radios when you get them second hand at a bargain. I've had a few and they worked well. Even had one of the larger double stack looking units. Any Bose videos I did after repairing a radio would get tons of dislikes, some videos with mostly dislikes 😆, some people have a ridiculous hatred for Bose.
I don't like Bose because of their behavior about repairs. I have 2 AWRs, one without CD and one with CD and remote, that one behaves like brain damaged. Only solution is send it in, get the board replaced, pay a bunch and ask yourself, what the heck was wrong with it - no answer at all to this - even if you are a professional - you get NOTHING from Bose at all! That sucks!
@@SilliestSmurfEver Customer service being bad or not so good, and not liking the brand because of that is understandable, but a lot of people have a blind hate for the brand which is a bit different. Granted, it's often a bit expensive compared to other stuff price to performance, but the products themselves aren't too bad, bad customer experience aside. I have never bought new from them, nor have I had them service anything, so buying second hand at a bargain it's been decent stuff.
The UD marking on the capacitor means that it's a low impedance model. It is a 47uf and should have a letter after the 47 specifying the voltage, but I can't tell what the rubbed off letter is. You could probably just test the voltage on the cap when it's in use and replace it with the next voltage up.
Hello Vince, thank you very much saving my day. I think UD is Nichicon UD series capacitor. rs-online shows data sheet of this type. The j behind the 47 is the voltage code (6.3V) Best regards Dirk
I got one of the older top-loading models of this from Freecycle a few years back. "CD player not working." 1 Q-Tip , IPA, and 10 seconds later: Working CD player. I gave it to my cleaner, with a Bluetooth adaptor. She loves it.
To pinpoint the faulty cap you can also try to cool them using coldspray or heat them up a little. When it is heat related the first I would check is around the heatsink.
I did one of those at a Repair Cafe and got the right cap on 2nd go using hot air as you said to kick start the bad one. Lots more needed doing but simply not enough time at a Repair Cafe.

I see some 05 datecodes, so I assume that's how old this machine is. Presumably it's seen a fair bit of action over the years, hence why so many electrolytics are tired. I'll have to look at my parents' 2001ish Panasonic SA-PM01 min stereo soon as well that handles their PC sound, it seems to have developed a hum so I suspect a tired filter cap or caps. I have my suspects after studying service docs (this thing does not have a standby power supply so the main power supply operates all the time), but they have yet to be confirmed.
Hey Vince , I see so many videos where people mention to keep clear of capacitors ! I used to work on multiple electric motors with large Caps , I had a 3 pin plug with just an earth cable wired up , then used to flash both terminals on pos and neg on motor plug it drains cap really quick ,
Yet again, a Vince upload saves the day. I was watching an hour long video about building a garden pond. My *cough* garden is about the size of a postage stamp and made of concrete. Thank you for saving me :)
I think you did alright just changing the cdrom board's capacitors. If you think on it, those caps might not get any power if the person never uses the cd player, so they're probably more prone to drying out. I mean as a matter of course, you should change them all but to hell with that. That really is boring.
Measuring the ESR of caps in circuit is ok, but you could get a better value as ist actually would be, for example when multiple caps are in parallel and one is bad but the others are good, you would still measure a good ESR because of the caps in parallel
I can understand how a bad capacitor can show good ESR good in-circuit, but not how a good one can show up bad? If the resistance is high, how could it be lower out of the circuit?
Turn those surface mounted capacitors 90 degree with the pliers. This is the easiest way to remove them. Pads will stay untouched. Than clean pads with soldering iron.
Interesting, I was thinking from the grinding noise, that it might be mechanical fault, for example some cracked white plastic gear in the laser moving system. I've got skipping cd player as well from 1992, and have been thinking it may be mechanical failure, but maybe mine has faulty capacitors too. I just don't have esr meter, so finding faulty ones might be difficult. So far haven't taken it apart yet, just taken some looks inside using endoscope, but haven't seen anything obvious. At one time I thought one of the rails, where the laser head moves, looks kind of "rusty", but not sure about it after all, how could it rust as it's kept always indoors.
Great video. I've been looking at getting a pack of caps like you have and I've been wondering where to get them from. Can you suggest a reasonable store? thanks
I have fixed a few of those over the years and I am finding more and more of those capacitors causing issues in electronics I have a Sony watchman Tv that I need to replce some those capacitors in !
I've never really used an oscilloscope properly, but theoretically, if one of the capacitors was bad, wouldn't it have an unsmooth voltage, which you could measure by powering up the board? Just a thought, please correct me if I'm wrong.
I new it! I have an old LG LCD tv and it goes continuously off and on if it's freshly turned off. If you wait a couple of hours, it turns on ok. I was sure that it was about the cooling down of the capacitors. But whoever I asked said that capacitors best work in warm state. I was sure this was not the case.
so what was the deal with the broken plastic pieces? how do you know they were not jamming up the CD player? when you took it apart they dislodged. did you get new foam?
A great channel with always something intresting going on, I do wonder however why you don't just burn a cd of free use tracks from the youtube library, top quality audio for testing and no content matching, is there some rule on youtube that says you can't ?
Hi Vince. Not sure if you have noticed a drop in viewership numbers recently. Perhaps it's just my end but wondered why I hadn't seen you in my feed recently. The last video I watched was you repairing a Beomaster. I thought you were on an upload break or something. Checking back that last video I watched is now 4 months old. Is the algorithm not pushing your content out. Seems I have a lot of catching up to do. Hope all is well. Myke
Thanks Myke, I think the last time TH-cam pushed me was the Amazon Return box video that I did last October time. I don't think my content is suited to the wider audience due to the length of my vids so views are dropping, but have been for years now. I'm just glad I'm still doing it, as I thought the end was nigh a couple of years ago now 😂
Nice fix as usual. I was hoping you were going to check the caps out of circuit to see if you could isolate the faulty one. You should write to Daniel O'Donnell, I'm sure he'd give you permission to play his CD on your vids as free publicity, not sure if you'd lose viewers though 😂
Supercaps are just like other caps: The voltage rating is the maximum allowable voltage. But the capacity is incredible. This one is rated at 0.33 F, which is 330,000 microfarad.
First thing I would have done is to have put a cleaning disk through the drive. Why did you leap onto capacitors before anything else? Edit - What did you do with the foam gasket? it needed to be positioned properly.
Foam gasket...what foam gasket??? I don't remember seeing one. I remember the foam breaking down around the speakers wires which fell down onto the board, but I think that was it. I did the caps as when it heated up by playing Aux in and the radio then the CD player started played fine so I thought it must be cap related 👍
@@Mymatevince The long snake like gasket that had broken down and deposited particles of foam on the PCB, that's what I meant. I presume it was supposed to be fitted in a way as to separate right and left hand channels.
Hey up Vince. These remind me of a Amdtrad ...... chuck it in bin ... 😂😂😂😂 actually sorry ,bose you made an improvement . The tube you mentioned is a resonance chamber. Or something for its technical term. Watched too many tech ingridients and diy perks ,plus other audio related channels . Also im practicing for going to a classy restraunt . Hey saw a hoom Dorm on ebay fawlty. 😮😮.... I have notnforgotten ,that converstaion ......😂😂😂 Great video.,great tips and wowsers ,dedication. P.s. These bring back memories of 80s in a different fashion , the sharp x bass , twin cassette back to back . WQ-T360E One of my portable radios ,used at work .
A point of reference: Never! (with all emphasis) handle Super Capacitors with your bare hands or metal tools. If you do you will short out the capacitors. Also holds true for watch batteries. If you don't believe me do your research. Further, if too much heat is applied to those capacitors [you replaced] they will explode perhaps into your eyes. Again, a bit of research will benefit. If you choose to ignore this last bit of information, wear safety goggles and don't breathe in the vapor.
I have 12 copies of the album, they’re in the garden hanging on bamboo sticks with string allowing them to spin to scare the cats out of the garden, and I play one copy to keep intruders out
@mymatevince I have a Bose soundtouch 2 with no power, ive had a poke around but have hit a wall, would you be interested in it for a video? If so how do I go about sending it? TIA
I tried making an audio phase cassette fm am radio work because the light worked but no audio and now it’s completely ruined with wires unsoldered and disorganized.
The CD player was stop starting not skipping otherwise the track numbers would have skipped also I don't think you needed to change the capacitors were alright despite the readings. If you watch at the very begging of the video you hear the disc drive making a clicking sound as like if there was a loose piece of plastic was stopping the disc drive from turning properly and when you have taken them out, you should have checked see if the disc drive was still stop starting and still was making that clicking sound before replacing any capacitors.
Generally (not always) EMC etc tests (to meet approvals) are done with shields in place. If you prise the shield off and refit it you could disrupt the RF shielding part (reduce metal contact and therefore increase emissions beyond approval limits). Though, a shield with holes in it has always made me laugh.
Looks like they picked this up from a bin or a landfill or something like that with the amount of dirt and damage it had i know it wasn't well maybe but it just looks like it was.
Why did you beep each cap out and why did you take photos? All you needed to do was put the new cap on in the same orientation as the old cap. They are amrked with a black mark after all.
You could alleviate the caps monotony by awarding ones children with punishments for fair or fancied misdemeanours... back home late... Hmm 5 caps for you naughty child and you can kick yer heels back and let these machines just fix themselves :P
Honestly BOSE radios dont deserve the premium price tag they do have decent sound but they arn't made well and even the high end stuff require special cables for interconnected components like you didnt pay enough for their products to begin with. Personally i rather buy a similar Sony or Panasonic product they often use better quality parts and look nicer.
I had a Bose wave radio like this. Bose is pronounced "Boze". By the way. The set I had was similar to yours but it had no remote. Cd player worked radio worked. I was using it and the audio just faded like the volume was turned down. Tried recapping it and broke one of the traces so I junked it. Kept the speakers/waveguide part and threw the rest away. I can find an amp to use with the speakers or a car radio.
ARGH! _Never_ grab a CD by the top and bottom: always by the edges, especially a Daniel o'Donnell CD. Also, _never_ put a CD down on any surface, especially carpet.
as someone who replaced surface mount caps by the hundreds whenever I was recapping something 15 years ago, the easiest way to remove them is to not unsolder them, but to twist them off the board with some needle nose pliers. the legs of them are designed to break away. then just clean the pads off, apply new solder, and then set the new cap. if you get into a rhythm you can replace a cap every 30 seconds. unless you run into a cap that leaked all over the board and compromised the pad so when you removed the old cap it ripped the pad off with it. but even with doing a repair for that, it still is far easier to just twist the caps off than to try and unsolder them.
I agree twisting is the easiest method.
I had heard that before but was always fearful of pulling up a pad especially around via's
I've pulled up too many pads like that. Guess there a knack to it. I'll play it safe.
I have a pair of tweezers for my Metcal mx-500. Makes rework a breeze for things like this.
What's the standard you're referring to that specifies SMD cap legs are designed to break away?

P.s. These bring back memories of 80s in a different fashion , the sharp x bass , twin cassette back to back . WQ-T360E
One of my portable radios ,used at work .
A point of reference: Never! (with all emphasis) handle Super Capacitors with your bare hands or metal tools. If you do you will short out the capacitors. Also holds true for watch batteries. If you don't believe me do your research. Further, if too much heat is applied to those capacitors [you replaced] they will explode perhaps into your eyes. Again, a bit of research will benefit. If you choose to ignore this last bit of information, wear safety goggles and don't breathe in the vapor.
I see it as every viewer's favorite album😉
I have 12 copies of the album, they’re in the garden hanging on bamboo sticks with string allowing them to spin to scare the cats out of the garden, and I play one copy to keep intruders out
good fix I bet an older person would like it for cd play back or radio
@mymatevince I have a Bose soundtouch 2 with no power, ive had a poke around but have hit a wall, would you be interested in it for a video? If so how do I go about sending it? TIA
There is a white line on the PCB marking the negative side of the electrolytic capacitors.
I tried making an audio phase cassette fm am radio work because the light worked but no audio and now it’s completely ruined with wires unsoldered and disorganized.
Super caps of that size are normally used instead of a clock battery.
Definitely that Daniel O'Donnell CD that caused all that damage 🤣
😂
got 2 of those things, capacitor problems are well documented, scourge of modern electronics
Hi Vince can i give you trick how easily remove smd elco. Just take a plier. Twist it and elco let lose will not damage the board . Try it
Yay crapacitors, my favourite.
Surface mount crapacitors... my least favourite 😞
awesome the video hope you get it fixed
Me gusta mucho tus videos ojalá sigas haciendo videos
lets go I am here early Wooooooooooo
(Edit: for me it is 3am and I feel that your videos are more important then sleep)
the tube system for the sound was developed for NASA and used on the space station
Daniels back 😂
There's Daniel In Blue Jeans next
A few hours later…will it work?
My bose just has the exact same Problem. I mean, will have had...
Thanksalot
Those SMD electrolytics are perfect for hot tweezers.
You should remove one and then test it with the ESR out of circuit.
The CD player was stop starting not skipping otherwise the track numbers would have skipped also I don't think you needed to change the capacitors were alright despite the readings. If you watch at the very begging of the video you hear the disc drive making a clicking sound as like if there was a loose piece of plastic was stopping the disc drive from turning properly and when you have taken them out, you should have checked see if the disc drive was still stop starting and still was making that clicking sound before replacing any capacitors.
MMV's Capacitor Madness.. I think I would go nuts too if I had to repeat that 50 times...
The poor guy changed the capacitors for us 😢
Big respect to my man 🫡
be careful, if the capacitor is on a negative voltage, then it could have its positive to ground
I have the same system with the same problem.
Hey it's my friend Vincent
My chum Vinny!
Why does the metalic shield say do not reuse?
Generally (not always) EMC etc tests (to meet approvals) are done with shields in place. If you prise the shield off and refit it you could disrupt the RF shielding part (reduce metal contact and therefore increase emissions beyond approval limits). Though, a shield with holes in it has always made me laugh.
Dude, use Sharpie to mark where negative was :)
Looks like they picked this up from a bin or a landfill or something like that with the amount of dirt and damage it had i know it wasn't well maybe but it just looks like it was.
I'm going to foster an educated guess @3:32 and say that it's a cold solder joint rather than a capacitor.
Bose sound quality is nice to hear specially if the bass kicks in
That grill at the end looks a bit yrllowed from the beginning of the video.
Why did you beep each cap out and why did you take photos? All you needed to do was put the new cap on in the same orientation as the old cap. They are amrked with a black mark after all.
Very interesting 👍
You could alleviate the caps monotony by awarding ones children with punishments for fair or fancied misdemeanours... back home late... Hmm 5 caps for you naughty child and you can kick yer heels back and let these machines just fix themselves :P
😂😂😂
Skipping CD Player.. Is that yo way of avoiding Copyright Strikes? 😂
I'm Kidding, Err-APU 👁👍
Vince really needs a copyright free cd to test these on 😁
Mashallah your knowledge is pretty amazing what a smart person
Honestly BOSE radios dont deserve the premium price tag they do have decent sound but they arn't made well and even the high end stuff require special cables for interconnected components like you didnt pay enough for their products to begin with. Personally i rather buy a similar Sony or Panasonic product they often use better quality parts and look nicer.
Is it just me that finds replacing capacitors relaxing and cathartic, not engaging content though ha!
I thought you’d have better taste in music Vince, I must admit.😂😂
I had a Bose wave radio like this. Bose is pronounced "Boze". By the way. The set I had was similar to yours but it had no remote. Cd player worked radio worked. I was using it and the audio just faded like the volume was turned down. Tried recapping it and broke one of the traces so I junked it. Kept the speakers/waveguide part and threw the rest away. I can find an amp to use with the speakers or a car radio.
Good to see you still around :)
ARGH! _Never_ grab a CD by the top and bottom: always by the edges, especially a Daniel o'Donnell CD.
Also, _never_ put a CD down on any surface, especially carpet.
Hi vince I've got a 2.4l undersink instant water system can you give me your po box I'll get it sent to u would love to see it on your channel
