Stupid speaker?

Thank you so much for your channel. I had been stuck in my deadend QA/Triage job for a couple years and was about to quit when I first started watching your videos. You do a great job of being informative and entertaining while still being humble about your ability. It was that that reignited my interest and made me insist to my superior to let my apply to their open solder tech position. Long story short three weeks of practice at home with your videos and various youtube tutorials to keep my company and a test last week and I am now a solder tech.

No, no, no brother Steve! its not! a fuse. FB is the designator for a 'Ferrite Bead' It acts a lot like an inductor, it filters out AC, and they slow transition of DC signals. GET IN - Satisfied. Shout, shout, let it all out The Capacitor is a thing It can work without, I'm de-soldering you Come on I'm De-soldering you, come on 😂👍

Just for future reference, there's fairly little point in taking an MCU off. Even if it is the cause of the fault AND you can source a new replacement, you still need the program the manufacturer put in it to make it work again, which is a non-starter in most cases. Better to diagnose a faulty MCU by process of elimination and then just keep the unit for spares.

Generally with low voltage electronics, all of the grounds will be connected(which is why every cap seemed to be "shorted"). If you do find a short anywhere, one good trick to narrow things down quickly is to look for fuses(or even larger inductors) - You can use them to your advantage to isolate the positive rails of different areas on the pcb. I think of them as little diagnostic switches you can open(remove), and then re-test to see what area is still shorted. Once you find one of those that clears the short from the majority of the board, you'll be down to a much smaller area to check for the culprit.

This is exactly why right to repair is so important. One small cheap component failed and normally the whole speaker would be thrown away. Having schematic of the board would have helped to diagnose the problem.

Patience of a saint Steve and well done for sticking with it - amazing to think it seems to have been all because of that tiny capacitor - they are so small in reality!!Great fix man!!😃😃

You asked how people make it look so easy, but we aren't watching those people. Your persistence is inspiring! People who know exactly what they're doing aren't fun to watch. I don't know how to repair electronics, but I'm interested. I love it!

Nicely done Steve 👌

Well done Steve. I’m not going to check all 399 comments because I don’t want to. I suspect Mr Sysm is a play on the word mysticism. NICE & SOLID 😊

Nice to have these videos..I can see how much electronics must've been going to waste just because of tiny components failing to work. Love you man 😘

Your style, expertise and innovative approach are immensely entertaining.

Good work Steve, you're getting better and better at fault diagnosis. Now word of advice, when you're looking for a short and start removing components, do not put them back until you've cleared it, why is this important? Because you can accidently introduce a short of your own by accidently making bridges etc, then it can become a real headache real quick. SO when doing this type of work and you suspect a component is the culprit and you remove it, and it turns out not to be the cause of the short just leave it out of circuit until you've cleared the original short, then resolder all the remaining components you originally removed back to the board. All in all good work mate.

Thanks again for the video, what a demonstration of perseverance! Always amazed by your capacity to create new rhymes !

Nice one Steve 😃👍

I LOST it when you said “FB? Fuse boy” 🤣🤣🤣 great fix Steve!

First off, im not british. I am from the u.s. so im not sure what your terminology would be but i will give it an attempt. Your sense of humor is so funny. Like when you said that was the question on your lips not everyone, that would be weird. I guess its cheeky as you guys say. It is hilarious. Your cheeky sense of humor. Is that right?

Nice Fix Steve, well done! I had the same problem with one of my Hikvision cameras a few month back. Those pesky surface mount caps!

I love these longer types of videos. Great job, Steve!

Hi Steve, i'm pretty sure I've watched everything you've put out. This is a new favourite. I learnt loads from this. Yeah, this one is your best work so far. And yes, I said solid.

Enjoyed that ! Your infrared camera link, links to a humidity tester on Amazon , by the way.

Nice detective-ing! I wonder if Sysm could check the value on the other speaker 🤔 Guessing that cap was just doing a bit of stabilization or filtering that's not strictly necessary

I have been binging your channel for a week or so and I am seeing a theme of , Voltage regulator chips, capacitors of ever increasing smallness and flyaway ability, also usb sockets being mangled being the fault usually and also they seem to be the most annoying jobs and very fiddly, I salute your patience. During lock down I bought myself a soldering iron station and a multimeter and all the gubbins, it's all still in the box lol.

Oh my gosh, this video is amazing. Thank you so much - I'm learning a ton from watching you fault find through these. You're one of the people who inspired me to start learning about electronics and I've even made a little bit of side money from repairing them and reselling them thanks to you. You truly ignited a love for things like this that I didn't know I even had!

Could not describe how I love your videos, they are just like some comfort food to me but in digital form. Love so much Steve.

Dear Stezger (did you see what I did there - did you see??!!) your timing is impeccable Sir, after spending the afternoon repairing a fence panel in my Mums garden, picking up the requisite Indian takeaway, I come home to a brand new video from you! Wonderful to watch and eat at the same time!

Great job! You could probably email Mr. Sysm and ask him to open his working speaker and see what the capacitance is on that part :)

Nice work Steve. fantastic that you got it to work .

Aw yes some Saturday night SOLDER PRON!

Don't rely on the beep of a continuity tester to indicate a short, remember it still sounds with low resistances too. Double check with ohmmeter

I don't know how you do it.... !!! Bounce from one component to another..and you fix it.. bloody brilliant!! Love you channel 🤩

Steve you crack me up. Excellent diagnostics and delivery. Thank you!

This was a great video Steve! I was kinda worried there for a minute. Very nice trouble shooting!

I love how your laugh matches the boot up tone of the speaker

I dont understand alot of what you're doing and saying but enough to follow along. It's good to see old things fixed and used. I've had no end of stuff thrown away to a variety of issues over the years I'd of loved to of seen fixed and in working order again. Great videos man

I think this is one of your best wins, well done.

I don't normally listen to VOS, but this time he was on point. Love watching you fiddle with things no matter if they end up working or not. Appreciate the content Steve!

Well found Steve ... perhaps this is the opportunity to get yourself a short circuit finder? I can recommend the VC480+ Milliohm meter but there are plenty of others which can help narrow the search. See Learn Electronics Repair channel’s video ‘MicroOhm Meter Short Circuit Finder Review Comparison...’

Good One! I think it's amazing how quickly your channel has grown. I remember when you hit your 5K subscribers. There I was still hoping that you would soon make 10K subscribers, but it looks like you may have reached 100K soon. Keep it up!

Fuse Boy! Lol As a Texan, I approve of the accent.

100k is close keep the good work man ✌✌

Love how you do all type of items .. gday from Australia 🇦🇺

I'm a new subscriber and you have already improved my life. My repairs don't always go well but I've identified my problem. I'm going to trade my multimeter in for a new multimeter. Things will go better. Thank you

This video had me cracking up the whole way through. So good. Especially liked the 'Fuse bouyyy' 😅

The "and that's moving edit" really made me giggle, thank you

Love your videos. Love the TFF ending. Hate small caps. Rock on! :D

So thermal camera to the rescue - seems every tool box now needs a new tool for this type of work - Good save and much fun watching .Niccceee

I wish you said I O you and apology. You’re the best! I know nothing about any of this but find your content super relaxing and educational. Thanks!!

I love what you are doing. Could you give us more scale on the things you use and the stuff you are fixing. Perhaps introduce something as scale reference like a 1cm cube of blutac?!

WELL DONE !! The satisfaction of a fix is second to none. Great content Steve.

Ive been Watching a bunch of your videos lately, very good stuff I must say! You won over my sub man, keep it up!

Excelente video la paciencia que le pones para poder arreglar saludos desde Argentina

Way to go, Capt. Bodge.

ahh the old red herring went down the rabbit hole for a while 🙂. Nice fix enjoyed it.

Man you have a charm with you when doing this and on top of that you make me smile ,i subbed !

Dude you deserve a million subscribers I'm definitely sticking around for that day

Man that singing was great. Great job

Incredible tenacity on this one!

This was by far the best flow for the Patreon Shoutout.

Another great fix.. Btw us mortals don't realise the smallness (is that a word) of the components you are dealing with. Well done Steve.

Very Nice Steve. I learn more and more. Thanks for sharing.

Gettin better and better!

I love how you are seemingly descending into madness.

The song sections are my favorites!

Well done, good job Steve. I love watching your videos. I think you are absolutely hilarious 😉👍👍

Thanks so much for you content, it is because of you I fixed my 42" TV, I would never have attempted it, do not have the tools you have but in the end I just swapped out the small circuit board that I found was faulty, and hey presto all fixed. Thanks so much keep the great videos great fun!! Stupid TV! 😃

I own one LG PK7 Boom box +Meridian. I'm still genuinely impressed by it's build quality and of it's impressive bass output from two passive woofers. The battery lasts about 8 hours at full volume per charge. However in my opinion, the charging is the biggest drawback as it requires a dedicated 19vdc charger brick. It would have been most useful to be able to charge it with a 12vdc brick.

Get yourself a Voltage Injector Tool on the shorted components to see where the heat is coming from

God inlove you so much, its Like therapy when i listen to you, many thanks and sorry for Bad english

Loved that Steve. Not been on your channel for ages but I was talking to Vince a week or so ago and he mentioned you. Your channel is doing mega since Christmas (I did one of the Vince YT fixers Xmas specials) I know nothing about electronics but I loved this video mate good fix!

Just for future reference; MCU = Microcontroller. Replacing it won't work without the firmware. They come blank ,or with a default program from distributors (mouser, digikey, etc). If you're buying thousands you can discuss buying them pre-programmed from the manufacturer, a few hundred and you'd have the PCB assembler program them in circuit as part of the assembly process. You can program them yourself, but you need access to the specific "I'm a bluetooth speaker" program written (or commissioned) by LG

Watching a week later and your already 1k more subs. Fair play to you Steve your doing great. I still haven't hit that 1st 1K so know how much of a achievement it is to get these great number :) Also that was a shock, 1 tiny component like that stopping it, also shocked it worked without it tbh haha

When testing capacitor for shorts with a cont or diode test on a DMM , you MUST back up a short by testing the resistance because its HIGHLY likely that they aren't dead short , but just very low resistance so , find a shorted one , check the resistance , as you get closer to the bad one you will get closer to a dead short on the meter

What a repair!!!! Good find, Thermal cameras for the win!!!

Really nice fix Steve! Even that cheap thermocam helps a lot. At least in case the short is low resistance.

I have no idea what you are doing 1/2 the time but I love watching your videos =)

Well done Steve I was feeling for you mate but you came though with flying colours you are getting a very clever man 👏👏👍😊love your videos keep them coming mr Steve

Very satisfying fix pal, great job :) May I steal Fuse Boy?!

I really enjoy your humour on these vids. Great stuff

You were "sad" when it wasn't the MCU.... Being someone who writes firmware for MCUs I was happy for you. As there was no way you are going to replace that STM and have it work without a donor from another unit as it would need to have the firmware that runs it flashed onto it. So seeing that the problem was something else that was probably just a failed component was the best outcome. Good stuff. I love watching your videos. You have such a good attitude and a hilarious way of going about it.

Great video, Steve. My kid burst out laughing everytime the little chipmunk voice and character came on. So my childs joy was a nice bonus to this video. Thanks for the content.

Wasn't expecting to see Bolton, always weird when you find out you're in the same general area as someone you watch.

gotta love when Steve says stupid

New subscriber here. Looking at your "info" to see if you've linked to your little thermal camera and you have! The only issue is it's out of stock on Amazon and there's no clue if it'll be back in stock. Such a handy little gadget. What swung it for me was seeing "My desoldering gun that goes moo" as that made me laugh out loud. I was at a demoparty a few years ago, I was with a mate and we've got for the same desoldering stations that both go moo and it became a bit of a cow joke while working on boards :)

Ah the joys of MLCCs - well done chap. As people have said, no point taking an MCU off unless you have the programming ability

Gordon the Goffer squeaks with hilarity, testing USB, gives Steve no more clarity. I love a good vid with a satisfying ending, nothing worse than a solution pending. I would record you this rhyme if I had my own video, but I only ever watch to hear u say "Monkeyjoe Tokyo" Peace!

By-the-way, FB is not 'fuse' but 'ferrite bead'. It is a component used in-line with a power supply to suppress high-frequency noise.

Maybe you should build or buy a short finder. most models work in-circuit and use low voltage, so the PN junctions don’t turn on. This means you usually don’t have to remove ICs and capacitors during testing.

Hi would you consider fixing 1980s Nissan electrical widgits because I think it would be really interesting and I own two. Also broken stuff is cheap and working components worth a mint.

19:01 🤣🤣 That should be a new T-shirt slogan. “Fuse Boi”

Perseverance pays off. Great video Steve. 😁😁

I love VOS please don't listen to the haters!

The proverbial capacitor in the haystack, eh? Lovely fix and epic rap :)

"Fuse boweh" That made me cry a little 🤣

nice one steve. entertaining as allways.

Thank you for telling your air temp + speeds :)

FB is likely a Ferrite Bead. Will read as a short. Will act as a fuse somewhat if you try and push amps though them, but not what they are meant to do :D

Steve, you have an acoustic guitar! You know what to do with it!

Nice bit of troubleshooting, that cap might have been hard to nail down with the chip on so as it turns out that was probably the best approach.

Great video mate! Awesome problem solving.
