Sonos were the company that didn't want to support their old hardware any longer, so they announced that they were going to brick all the old speakers, rather than let them keep working and not support whatever functionality the new speakers supported. This was unacceptable for old speakers but ,when they announced it, there were still speakers being sold that would be bricked shortly afterwards. The "good" news was that you could get a discount on a brand new piece of technocrap that could be obsoleted at any time, as long as you spend more money. Needless to say, the backlash made them rethink this brilliant plan to increase company revenue at the expense of consumers. Personally, I wouldn't buy a device whose stereo line-in jack can’t be used without registering an account with Sonos, but maybe that is just me.
Yes, not a fan of these types of thing either 👍
This. It's, in my opinion, the most obnoxious thing to do to your customers.
Sonos was a flatout scam ! Avoid !
That's why there are many company's products I won't buy for me this includes Apple from the old day I would never own their products.
What a bloody palaver just to get into it! Best way to deal with this buggers is don’t buy anything again from them! I ask about technical support before I buy anything now! The throwaway option is finished now! There is so much plastic in the oceans now that it would cover an area twice the area o France!🤬!!! Fraser
Another epic fix. I know linear regulators get a bad rap.....but I don't recall that they used to explode quite so often as these SMPSUs seem to - they tended to age gracefully ;). SMSPUs are great when all is well, but they really aren't tolerant of much abuse are they. Occasionally makes one hanker for a good old mains transformer, a bridge and a smokin' hot regulator transistor ;)
😂😂Cheers 👍yes old school linear regulators were a whole lot similar and didn't blow up as spectacularly.
Good stuff, i repair these all the time - they have a wealth of different issues. Main thing to do when taking apart is discharge from the bridge rectifier with a discharge pen (definitely get one, they're cheap) as they often hold onto over 300 volts for days. Always enjoy seeing your knowledge at work 👌
Thanks I'd been meaning to make one for a while👍
Another great repair, Mick. Not a Sonos fan at all, but that didn't stop me enjoying your tenacity in getting it fixed again!!
Thanks 👍 yes not a Sonos fan either 😂😂
Good job and good video thank you 👍
Thank you too 👍
Nice repair video. Also, I appreciate that you fast forward through the disassembly (unscrewing screws)
Cheers 👍
Only started the video but I could swear I've read articles before about Sonos purposively bricking their older speakers with firmware updates.
No idea which ones and maybe I've the wrong end of the stick but it's about all I know of the company.
Yeah i believe its the first generation of sonos speakers getting bricked. Although they stopped bricking speakers a few months/years ago cause people where complaining and sonos actually got in some trouble i believe. What sonos did was replace the rootfs with a dummy one which could not have all the functionality of a regualr sonos speaker and they also prevented old gen1 speakers from connecting to the app but i could be wrong
Might be an old thread but the CEO of Blackberry took over and they weren't going to Support old Sonos Bridges.. Everybody with the old type original kit kicked off and they are ok as long as you don't try and upgade them through the app...We.all know what happened to Blackberry.. Ha ha
They didn't "brick" gen 1 devices (this video shows a gen 1 play 1). Sonos moved to a different software system, so their old speakers don't communicate with their new speakers. You can still use the gen 1 speakers exactly how they were originally made - they're just not compatible with the new speaker infrastructure so two different apps are required.
@@thisisntforsharing then the rumors about recycling mode might have pointed to what you said instead of replacing the software, they moved to a newer software and ecosystem
Excellent investigative repairs., Mick. I hope your having a great weekend. Thanks for sharing.
Cheers Brian 👍Hope you have a great weekend too!
44:12 - Its OK to solder like this, but there is another method, you can solder two SMD resistors, in Λ shape, where one is left one is right, upright position tilted, in that way, ends are soldered with full width of component, and you are soldering them away from PCB layer (possibly GND or shorting to another signal).
Ah yes I forgot about the tombstone way. These resistors were quite tiny, so I just thought I'd do it like I did. I didn't see anything around them that would cause an issue.
Hi Mick, great stuff from you as always, many thanks from Nr Chester.
Cheers mate 👍
good job. but i couldnt spot your mistake. i thought you would explain it at the end
The first chip I fitted was a mosfet. 4141 was the number on it. It was one of the 5 ICs they sent! Not even the correct part.
I see why you said it was like a Repair Cafe fix I did of switcher, current sense diodes, bridge, and fuse, so I knew after seeing the toasted low ohm resistors the other likely bits you'd have to fix. But I wasn't expecting that secondary diode at all and can't make sense of that. Secondary side faults rarely damage anything on the primary, and vice verse, Most odd. Was the switching chip actually faulty? Probably if the gate drive resistor was also dead.
Yes, I'm pretty sure the switching chip wa s faulty especially with the gate pin resistor OC. I would have just changed it anyway regardless.
@@BuyitFixit The switching chips are what I pretty much never have to hand, so unless top blown off or test utterly bogus, last bit to swap for me. The ones with integrated MOSFET usually have top blown off so you have to grub around to find the shards to try and work out what it actually used to be. External MOSFET ones usually survive, but I agree yours there was probably toast.
Another great video. And you fix it even it was very blown up. What leads you to the small faulty 148 Ohm resistor?
Cheers 👍I said in the video the datasheet, and it looking like the chip was starting to run and then shutdown like it was sensing something not right (although it could have also been the IC faulty)
@@BuyitFixit Thank you for reply.
Thanks kindly for another excellent video. After seeing this and researching Sonos a bit I think I will stay clear of their products. Glad those capacitors were fully discharged. They can be nasty. BTW, if you ever have the opportunity to replace the batteries in an Onkyo OKAX6B/10 Portable Bluetooth speaker I would love to watch. I have one and it is great, but the batteries no longer take a charge and I have no idea of how to get into i without destroying it. Thanks.
You're welcome. I wouldn't buy one of these Sonos products either. I'll see if one of those speakers pops up on eBay 👍
45:13 😱😱😱😱
You did something wrong. It didn't explode 😱😭😭😭 and you didn't like one of the best world wide distributers
"Ali -never send original spare parts ever -Xpress " to. Why😭😭🤣🤣🤣🤣🤣
Super nice repair 👍👍👍👍. Very well and amazing.🍻
Cheers mate, I'm surprised it didn't explode with a bloody mosfet instead of the switching IC..Just a wiff of smoke instead 😂😂😂
Yes when you text said did you see the fault I looked and saw the IC number was different.
The R178 goes from pin 6 to the source of the FET i.e the top of the 1R resistors that blew, this is quite common fault on this type of switching IC. When the FET goes short it blows the current sense resistors then the rectified mains gets connected across the switching IC via the FET gate series resistor and the current sense pin series resistor blowing all 3 items.
The current sense value on this item should be 0R33 but because you fitted 3 x 0R82 it ends up as 0R27 quite a bit lower. But TBH as you found out that it still did not stop the whole thing blowing even with the 0R33 in when the output diode failed.
Thanks for that mate, I didn't realise at the time that they were current sense resistors, but someone else mentioned that, and it makes total sense (no pun intended 😂😂)
Today I tried to repair a bosch battery charger. The problem is that many components are erased by the manufacturer. I tried to determine what value of capacitor I should put in place of the suspect one. I thought I was not wrong by much. I plugged it into the mains, no explosion. And after 10 seconds, Boum !🤨
I think I will abandon this repair.
Damn, shame. Unfortunately it's just the way it pans out sometimes...
Your patience and persistence was tested on this one eh..bad parts didn't help. Hope you get refunded on the components that were no good. Troubleshooting this was brilliant, I never could figure out which culprit was next, good job. Nice video and great repair as always, thanks. See ya next time.
Cheers Terry 👍
Not so smart when it blows its self up 😂😂😂 like your switch on blowing up test, can’t hear you lean back 👍👍👍👍🤣🤣🤣🤣🤣🤣🤣
😂😂😂😂Cheers 👍
Well done on the repair. I wonder which component failed first, so taking down some others? The diode perhaps?
One of the morals of the story: don't buy electronic components from AliExpress (or similar outlets), it's a false economy. 🙂
BTW, when you fix a Repair Cafe product for a video like this is it because the owner has decided not to keep it or do you still end up returning it (where the owner may then make a voluntary donation)?
Thanks 👍I'll just charge for the parts ~£10-15. The problem is that some parts you can only get from the likes of Aliexpress.
Mick, me and the other half have struck lucky. Just found a VAX Blade 32volt vacuum cleaner been dumped at the local WEEE Bin. Thing is, there is NOTHING WRONG WITH IT, AFTER FULL INSPECTIONS AND CHECKS!!! 😯😯😯😯😯😯😯😯😯😯
Just needs a good clean up. These things aint cheap to buy, what an absolute waste, throwing this good stuff away.

Nice one 👍I've seen stuff like that happen before. I'm sure people just have too much money 😂😂
@13:22 I would probably call it quits, figure out the voltages and add an external power supply. Kudos
That was going to be my backup plan if the transformer was open circuit or shorted 🙂👍
Modern chips (since lead free solder) have a shelf life after which the pins are too oxidised for flow soldering. Some can be recovered by cleaning contacts with abrasive and the use of tin/lead solder. Really old chips solder well because old solder cleans up well with ordinary flux. Possibly cheap chips are just old.
That was leaded solder being used, so nothing to do with it.
Good fix. I know you like your low melt for component removal but I would recommend wicking it off properly afterwards - if left on it can be brittle and the joint can crack with thermal cycling.
Thanks Andy👍Yes I normally do wick it off (like I did on the small resistor) perhaps I forgot this time on the diode? I can't remember tbh.
A very interesting troubleshooting session, mate. Getting the wrong or fake parts does not help the troubleshooter. Great job.👍👍
Thanks👍 yes fake and wrong parts don't help at all.
You are done good trouble shooting sir but still i have confusion and i am looking from datasheet it is showing the 100 ohams resistor but you did the fixed 148 ohams how is this possible can you explain and onece again thanks for the sharing good information.
I didn't see any values on the datasheet, but someone had the a similar fault where the same resistor was blown and someone measured the value and said it was 148 ohms.. So I gave it a go.
Another battle hard fought and won and you say you aint no expert a very advanced novice. Great fix thanks for sharing.
Thank you 👍🙂
What a mess, I always think you are a brave man to fully assemble items and then fully test the functions . That item was close to being parts donor!
Thanks 👍yes a bit damage on this one.
Another great diagnosis and contribution to your local community, well done Mick 😀
Cheers Mike 👍
That’s the way to fault find keep at it ull find it, an old friend of mine who worked on aircraft electronics used to put a larger fuse in till it didn’t blow and then the faulty item would lol.
😂😂😂😂Cheers 👍
great video..! as an ex-TV engineer its great to see things being fixed...i do miss the old days of fault finding.
Thanks 👍
Thats the first time ive ever heard frustration in your voice 😀 great work as always
😂😂😂Thanks 👍
"I'm not a fan of these types of capacitors" is begging the question.
😂😂😂
Nice
Cheers 👍
Pffffff what a hard fix i think you give up almost haha 😊
😂😂😂Yes got there in the end though 👍
The 3 resistors are for current sence circuit. They are parallel.
Ah yes makes sense. I thought they were just protection but current sensing makes sense 😂😂
I've ordered probably close to a hundred semiconductor things (discrete and ICs) from ebay/aliexpress and TLDR more than not had a bad experience. Chips are often sanded and rebranded, outright fake, or as you experienced in a prior video they put for eg a 2n2222 transistor die in a large power package so it still tests like a transistor but blows up with any real load applied(ive verified this with decapsulating the die and looking under microscope). Now the only chips I buy from these places are vintage chips not available elsewhere. For repair I source it from digikey, etc cause even with the $8 shipping, its worth not being sus in the new parts.
Funny how you have a "dim Bulb tester" We have a Dim Bulb running for President :-)
i agree
@@VSteam81 Not so bright eh?
Please, shove American politics into everything. The rest of us aren’t human enough to respect.
Happy day, another video/repair and a tricky one.
Thank you 👍
WOW! The ammount of problems that speaker had and u still managed to fix it! It blew my mind - no pun intended 😂. Is there something electronics wise u can't fix? I'm not gonna lie i was thinking u may had to give up on it if u found another massive hidden problem that cound't be fixed, but once again u show us how the pros do it. Stupendous work!!
A bit of a challenge that one was... nice job!
Thank you 👍
It should be a law that once you decide you stop supporting the software you have to make it open source to let others continue supporting it. Or at least make it work without needing servers to work.
Great fault finding and patience, too.
Cheers 👍
Nice job once again
Thanks again!
please include the circuit board serial no's for those of us who can't afford a fancy microscope...thanks 😁
Those three one ohm resistors look to be paralleled so (any) values to achieve a total of 0.3 ohms would fit on those pads - three resistors being used purely for power dissipation reasons.
Considering how expensive these things are that's pretty nasty inside. Resembles generic Chinese tat in all honesty.
Great job well done as ever.
Thank you 👍
I’m sat here shouting solder ball at the screen 😂😂😂
😂😂😂😂
@@BuyitFixit I noticed a solder ball appear when you were soldering in a component and thought,, Is that bridging two tracks ? 😂😂😂😂
A true struggle.
Yes Indeed 👍🙂
Epic fix. Well done 🎉

There are loads of them on Amazon and Aliexpress but note they have embedded magnets that you have to dig out if you do any mechanical clock/watch repair.
@@BuyitFixit thank you very much.
@@gadgetmind Thank you very much.
