- Mr Sysm very kindly donated this LG Bluetooth Speaker to the channel. He's previously replaced the USB-C port and installed a brand new battery and all seems good, but it still doesn't power on!
Let's get troubleshooting the board and see if we can work out what's wrong with it!
Hope you enjoy!
Steve

Stupid speaker?
@wut shtoopid
I've got a stupid Sonos that makes a stupid hum if you fancy trying to fix that. You can keep it. I'm not after a free fix.
capacitor
Every video … I hear the outcome before watching it
Stupid shorted capacitor
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.
This is a great story! Well done. Also well done Steve for inspiring people
Congrats
Congrats on finding passion in your work.
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 😂👍
Thanks brother Steve! Ferrite Bead makes much more sense than Fuse Boi! I should have known that! 😬🤣

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!
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.
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 😊
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.
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.
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!!😃😃
Thanks Greg! Yeah, it was super satisying to find that little cap! Really enjoyed this one! 👍
Aw yes some Saturday night SOLDER PRON!
cues up "Solder Boi"
Nicely done Steve 👌
Thanks Vince, I really enjoyed this one! 👍
I LOST it when you said “FB? Fuse boy” 🤣🤣🤣 great fix Steve!
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 😘
thats why there should be more places where things get repaired instead of throwing away everything. An companies should start to make things again which last longer then just a year or two
@@mutosanrc1933 they were actually making things easy to assemble and disassemble.. making it easier to repair. Things weren't compact and glued too tight as well in earlier those days, I remember that old Mac PC was so nice to maintain and then things got changed to the extent that we're forced to dump them if slight damage occurr.
unfortunately it's a question of economics, these components and boards are so cheap to make these days, even if it's a tiny fault like this, it easily takes an hour of work from a skilled person and will cost you more than just replacing, that is if you can find anyone capable of doing this.
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.
Are you ok, Steve? No video for this week yet
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.
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.
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 love how your laugh matches the boot up tone of the speaker
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
Thanks AFU! Yeah, I don't think it's that important but I could definitely ask him if my one starts behaving odd. Working perfectly though and it's a great little speaker! 😊
Fuse Boy! Lol
As a Texan, I approve of the accent.
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...’
Nice one Steve 😃👍
Thanks Plantmilk! 👍
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?
Thanks again for the video, what a demonstration of perseverance!
Always amazed by your capacity to create new rhymes !
Thanks M.GN! Really enjoyed working on this one! 👍
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 :)
I love these longer types of videos. Great job, Steve!
The "and that's moving edit" really made me giggle, thank you
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!
WELL DONE !! The satisfaction of a fix is second to none. Great content Steve.
Steve you crack me up. Excellent diagnostics and delivery. Thank you!
gotta love when Steve says stupid
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.
Nice. Well done Steve.
Incredible tenacity on this one!
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!
Another gem. Thank you for sharing!
Great video Steve!!!!!Great repair job once again!!
Get yourself a Voltage Injector Tool on the shorted components to see where the heat is coming from
What a nice job!
Great video, Steve 👍
WOW! Congratulation!
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!
19:01 🤣🤣 That should be a new T-shirt slogan. “Fuse Boi”
Outstanding video as always. Great job Steve.
"Fuse boweh" That made me cry a little 🤣
Gettin better and better!
100k is close keep the good work man ✌✌
Man that singing was great. Great job
Well bloody done. 👍 👌
its been awhile I hope all is well
This video had me cracking up the whole way through. So good. Especially liked the 'Fuse bouyyy' 😅
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.
Perseverance pays off. Great video Steve. 😁😁
Love these longer vids!
Amazing Repair!
well done
Nice work Steve. fantastic that you got it to work .
Thanks Frederick! Super satisfying this one! 😍
Really nice fix Steve! Even that cheap thermocam helps a lot. At least in case the short is low resistance.
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!
Nice job!
wow nice fix!!!
good effort
Thanks foo
I love how you are seemingly descending into madness.
Very good work, Captain Bodge! 😁
What a repair!!!! Good find, Thermal cameras for the win!!!
Well done, good job Steve. I love watching your videos. I think you are absolutely hilarious 😉👍👍
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 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?!
great pinpoint and fix!
Way to go, Capt. Bodge.
Very Nice Steve. I learn more and more. Thanks for sharing.
Thanks WanJockey! Much appreciated! 👍
Enjoyed that ! Your infrared camera link, links to a humidity tester on Amazon , by the way.
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
I really enjoy your humour on these vids. Great stuff
I don't know how you do it.... !!! Bounce from one component to another..and you fix it.. bloody brilliant!! Love you channel 🤩
Beautiful Fix and keep going.
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
Awesome video as always bud
This was a great video Steve! I was kinda worried there for a minute. Very nice trouble shooting!
Thanks Chris, much appreciated! 👍
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!
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
ahh the old red herring went down the rabbit hole for a while 🙂. Nice fix enjoyed it.
The song sections are my favorites!
I think this is one of your best wins, well done.
Man you have a charm with you when doing this and on top of that you make me smile ,i subbed !
thank you......, and good video
Thanks for the awesome videos Steve! Just a question, where did you purchase the microscope bracket from?
Nice Fix ...
Ahhh Gordon the Gopher....lord that thing used to irritate me 🤣🤣
Love the song ❤️
Naughty capacitor, bad bad bad capacitor, clever clever clever Steve 😁
Great video mate! Awesome problem solving.
This was by far the best flow for the Patreon Shoutout.
Excelente video la paciencia que le pones para poder arreglar saludos desde Argentina
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 love VOS please don't listen to the haters!
Ive been Watching a bunch of your videos lately, very good stuff I must say! You won over my sub man, keep it up!
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 have no idea what you are doing 1/2 the time but I love watching your videos =)
Dude you deserve a million subscribers I'm definitely sticking around for that day
