yup, can confirm. just got mine to work with the jaycar 100V 3A diodes. bit bigger and they're not the same casing but you can make it work. i believe these FR diodes get a bit hotter than the B2100 so just make sure you leave the diode with plenty surface area to dissipate the heat.
Did the same, and it works just fine. So disappointed with Bose that a small component is so unreliable. Bose quoted $200 to fix it while the component cost 0.50c
Amazing and thank you so much. Your solution has fixed mine too. Diodes from China on eBay- I ended up receiving 50 by mistake so plenty of room for errors, but did it with the first one. Used a pointed scalpel to remove the glue- cut down vertically in the shape you want to remove then just lever up the glue. Worked a treat. I'm sure people know this, but for soldering, hold the diode upside down very gently in some small grips and dot solder on both the terminals. Hold it with tweezers in position and just apply heat on each connection until the solder melts and sinks down- be patient. Hold it in place until the solder cools then do the other side. The line on the diode goes to the left- hard to see on the original. Thanks again and much appreciated.
Many thanks for sharing this. Part ordered on eBay,delivered from China to France in 2 weeks. Subwoofer fixed and now working ! The most annoying thing is to remove the glue and clean the contacts on the board after removing it. I should advise using a iron soldering where you can set the temperature.
Thanks! I went to the local shop and they gave me a normal diode 60V 3A I believe, they told me it is sufficient. I also removed the glue around the diode using a precision knife instead of heating it. It took a bit longer but it was less messy. It works fine afterwards.
Thanks for this video. Ours died just before Christmas and conveniently after warranty expired. I thought I made a mess of it and had no expectation of a glowing light after powering on, but it did! Massive thanks to a commenter here who advises adding two blobs of solder to the reverse side prior to installing; this helped massively.
Thnx tonne mate !!! Acoustimass back to life after 5 months !!! B2100 is out of stock across the entire world..... finally tried an alternative- SS210 works flawlessly...... lets hope it stays that way. Though couldnt solder myself..got it done from a local shop...
Thanks very much for the video. I had exactly the same issue with my Bose subwoofer. After 4.5 years, it literally just died overnight. Glad I found this video. I followed the instructions and the subwoofer is working again. The link you provided for the part, the supplier was out of stock. I found the part on digi-key. Glad I ordered five diodes as I fried one on my first attempt with a large soldering iron. Downsized the soldering iron and solder wire to 0.7mm and got the job done. Thanks again :)
Thank you so much! I have no experience with electronics but a bit of patience and the help of your video I fixed our sub for £3.96. Bose wanted £180! Really appreciate it 🙏
Thanks for the posting. My woofer also lost power. I have ordered diode B2100A-13-F SMA(DO-214AC). However in the motherboard it was only B2100. Still we replaced and it worked. Amazing
Yep, can confirm , this worked for me too. I had nothing to lose as the sub was given to me and died shortly after. I bought a 10 pack of the 2100 things and with no electronic soldering experience I managed to delicately get it sorted. Thanks for the video.
Fantastic video. Gotta be honest, I had my doubts when first watching it, but had nothing to lose as the subbie wasn’t functioning anyway. Was very pleased to see the light come back on again and power up. All for the cost of about $30 for 50 little microchips. Thank you thank you thank you.
After replacing the diode the device goes on and works sometimes a minute sometimes longer then it turns orange, off, white on and works again. And this goes like a loop. With the 3,5mm jak same issue. Any idea ?
Thanks for the video; parts arrived this week, and I just completed the fix, all working as it should. Disappointed in Bose, but thanks to your video, it's all sorted for a few bucks.
Thank you for this video and guide we repaired our bose subwoofer by our self but instead of using B2100A-13-F (DO-214AC) we use SMD US1M UF4007 1A/1000V SMA Rectifier Diode Fast Recovery Diode. Success 🥳👍 again thank you.
Thank you so much!!! I never expected this too work. My piece had a lot of hotglue on it and it took forever to scrape off and use heat to get it off. But then I removed the part kind of jammed in the new one and added some solder. Plugged it in... AND IT WORKED AGAIN. Amazing. Thank you so much for the video!
Thanks for the video. Just repaired my dead Bose 300 subwoofer, though probably the worst soldering example set on earth but who cares… my bose acoustimass 300 subwoofer up and thriving 😊 Thanks again
I wouldn't put hot glue on the diode. That is probably the reason that it failed in the first place (my brothers Bose failed too and that had some glue on it)! Those diodes get hot and must dissipate heat into air. The hot glue is used around inductors to stop them whistling and also for mechanical fixing too. The person who was responsible for the hot glue was obviously trigger happy and covered over a critical component that needs to be in free air. If it fails again, next time clear away any old glue.
Thank you for this clear video. I have ordered the part on eBay as well. Received it within 2 weeks. Replaced it and the subwoofer works again. Happy me 😂👍🏼 Greetings from The Netherlands.
a great THANKYOU for you from the Netherlands. my woofer failt at newyears-eve ... found your video and did the exact same thing... except i didnt put the diode directly to the board but used 2 tiny wires so i was able to put on a more solid soldering. glued the diode to the board after isolating it. and away we go... boomboomboom 🙂
I had the same defect after 17 months on the BOSE Acoustimass 300, diode intact on the outside, tested with a multimeter and there was continuity in both directions of polarity. Thanks to your video, I ordered B2100A from china, arrived in three weeks, replaced and tested, everything is perfect. It is working again. MYTHICAL outie555
Hey, thank you so much for sharing this video. I had the same problem with my bose bass, ordered the chip on ebay, installed it after removing the old one. Soldering was a little bit difficult because of the small size of the chip and small space between the chips. I wasn’t sure if had done it correctly. But after testing the bass, it worked perfectly! Thank you 😊
Great Video, thank you! One question, can you tell me how to take the piece out under the circuit board? I need to disassemble to whole module. Thank you for any suggestions!
Thank you very much for this video! I have a question: I have an Acoustimass 300 (purchased in 08/2008) that stopped working this morning even though it was working yesterday and hasn't been moved for years. The LED does not light up anymore... How can I know if the failure can be repaired by your method? Is it (unfortunately) common enough to know that it's that? Comment: for the price of this equipment, it's incredible that the components of the subwoofer can just fail like this... Thanks in advance for your help!
Its almost certainly going to be that problem. It's such a cheap and relatively easy method to replace the chip so you've really got nothing to loose. Obviously I cannot say for certain that it is your problem but a lot of people have had this issue resolved with the method in the video.
@@outie555two thanks a lot for your answer ; for sure you cannot be 100% sure ... I've ordered the cheap and will try to do it properly ... I've contacted Bose afterasale service and they don't want to know anything ... repair is 145€ !!! I will try to repair but anyway, they've lost a client. Won't buy anymore Bose product. You don't invest so much money to have your system down after a few years. thank you so much for this video that helped so many people !

hast du das selber gut hinbekommen? ich hab noch nie in meinem leben was gelötet und auch kein werkzeug, sieht aber wirklich nicht allzu schwer aus. oder ich bring es zu einem technik shop und frag ob sie das hinkriegen nach der video anleitung.
Just double checking for reassurance as not ordered the diode yet, but does it simply sit on the circuit board with blobs of solder to keep attached? Thanks.
Very fiddly but all done!!! Never really used a soldering iron before and thought it wouldn't work as wasn't too sure if i soldered the right hand side correctly/sufficiently, however it did. Thank you so much for your expertise 👍 @@outie555two
Hi! I changed the diode you mentioned and the light doesn't turn on yet. Should I necessarily connect the board to the sub to check it works or is the light supposed to turn on anyway empty? I apologize if something isn't understood since English is not my first language. Thanks in advance.
I have had mine for not even 2 months i got it DEC 2021. The BASS module comes on, has the white light on, and is connected to the 700 soundbar and shows up on the app as connected. It just doesn't play any sound out of it at all. I don't know if this is the same issue or another one but its frustrating having something so expensive not work after such a short period of time.
Yours is a different issue. In my issue the power wouldn't do into the circuits and the led did not go on. Don't know how to fix your problem, but maybe on the remote press "bass" then volume up. That controls the woofer volume independently of the sound bar volume.
Well this repair video totally put me off from buying the subwoofer in the first place! Does anyone know if this issue happens with the Bose 500 subwoofer as well?? I wish premium products lasted longer😕🤔
Hi I’ve had the same problem but Bose repaired it. Now my soundbar 300 has just stopped working - no lights or response from it. Power is available and checked. Any idea what I should look for as a fault. Also item is out of warranty. Thanks
Can you give me advice my bose bass module 700 got wet. My basement flooded half inch of water so the cord and the base got wet and its not working anymore. Is there anyway i can save it?
I've done this fuxs and got know where , I've left it on for hours and nothing , I've plugged in a aux cord that plugged into nothing and about a minute later the orange light came on . I can unplugs the cord and it stays on but then even arfter that it does not pair up or even work via aux cord . And if I turn the power of it doesn't light up at all until I plug that cord in that I plug into nothing at all . Do you have any ideas on what to do next to get this to work ?
I have the exact same issue. Replaced diode but no light until i plug in an aux/jack cable into the ‘acoustimass in’ port. Then a solid amber light appears, but unable to link to the soundbar nor sound can be heard. Pls help!
I’m not an electronic expert, but my bass 500 Bose module stopped working for me. 😢. People on utube showed me the fuse , but I still couldn’t get it off. Any advice why my 500 Bose sub not receiving power?
I was hoping someone could assist me, there are two larger (2512 size) surface mount resistors on the bottom of the board when you first remove the cover. One is marked 7R5 the other is mounted with provision for another beside it. Could someone please tell me the value of the other resistor please?
where can I buy this diode? Do you sale or provide info where I can buy it please another question, for second sub, amber light change to white led for 2 second then goes red light and goes off for 5 second, (it is cycling amber-white-red) i think it has wrong FW, How can i upgrade subwoofer FW correctly? when I look in app, it show Subwoofer 700, actually it is 300.
How did you find out which part was broken? My bose speaker goes on and off again hasnt lost power completely but i wouldnt know if its the same part or a different one?
I found out by digging around the internet for what fails on them. Your problem might not be the same as mine just didn't turn on one day. But for the cheap cost of the chip, might be best to just try it.
Great Vid. I have the same Problem. But which diode can i Use ? I find DO-214 AC in 40 V and 60 V and 100 V. Which one i have to bye ? Sorry for my English
gracias por el aporte, me funcionó, en mi caso el diodo no estaba en corto circuito me daba una medición de 0.38V y en inversa me marcaba 1.8V sospechando de que este dañado remplace con otro shotcky diferente numeración respetando la capacidad de 2A. funciono. saludos
After replacing the diode my bass module 700 worked again but i felt the sound is broken(fluttering) . Can u please suggest any fix ? Thanks in advance💯
My subwoofer lasts 8 minutes working normally and then it turns off and starts restarting until it cools down again. Will it be the same problem? Will it be solved with that?
The faulty diode looked fine on the outside. You might be able to test it with a multimeter but if your speaker isn't turning on its probably that diode being faulty anyway.
If it's got the same woofer then probably would. They sell the same woofer but with different sound bars then call the package a different number, but is likely to have the same internal parts.
Hi Sir I have same issue, manage to disamble the unit but can’t see any damage to the chip, just a silly question can we physically able to see the damage and is it 100% this chip to replace not any other. Kind regards
You cannot physically see the damage to the chip. It's a common fault with this model and literally hundreds of people have swapped that chip out with a new one and got the speaker powering up and working again
nice job. i have bose acoustimass 10 series iv subwoofer. all other channels working good. but subwoofer sound is not normal. working but very low sound and not pure bass. very week bass coming. how can i fix?

Will this fix one that isn’t connecting the speaking? Mine is showing amber then white and red lights. Won’t connect
No, this just fixes the sub woofer if it is not turning on. The subwoofer has a light on it to see if it turns on.

Not the same issue that's fixed in this video. Without knowing what the solution is, maybe it just needs to be re synchronised to the base unit?
Great Video, but why on earth do you guys put hot glue back on the component ? For what reason ?!??
Assuming that the bass can make the chips walk, so reapplying what the manufacturer did in the beginning.

Thanks very much for the video. I had the same problem with my acoustimass 300. Now it is working.
Great news
I've done this fuxs and got know where , I've left it on for hours and nothing , I've plugged in a aux cord that plugged into nothing and about a minute later the orange light came on .
I can unplugs the cord and it stays on but then even arfter that it does not pair up or even work via aux cord .
And if I turn the power of it doesn't light up at all until I plug that cord in that I plug into nothing at all .
Do you have any ideas on what to do next to get this to work ?
I have the exact same issue. Replaced diode but no light until i plug in an aux/jack cable into the ‘acoustimass in’ port. Then a solid amber light appears, but unable to link to the soundbar nor sound can be heard. Pls help!
Very good and clear video ! I did repair like video and now the module works again. Thank you for sharing !
Glad it helped
I’m not an electronic expert, but my bass 500 Bose module stopped working for me. 😢. People on utube showed me the fuse , but I still couldn’t get it off. Any advice why my 500 Bose sub not receiving power?
Not a fuse problem in my video. It's a chip that needs to be desoldered from the board and a new one soldiered back on.
Danke für die Anleitung, hat super funktioniert! War nur ein wenig schwierig an die Diode zu kommen!
Kannst du mir sagen, woher du das Ersatzteil bekommen hast? Und es ist der 500er Bose genauso? Danke
@@kfxer5213 sorry, kann ich dir leider nicht sagen, müsstest du mal nachschauen…
@@michaelschwarz580 und woher hast du das Ersatzteil bekommen?
@@kfxer5213 Über AliExpress…
Many many thanks!! Worked :-) Greetings from Germany
You're welcome!
That is interesting because I bought mine and it immediately didn't work. Made me rethink about bose. I am less likely to buy from them now.
I gave mine to a local repairer and he's struggling at the moment. Is there an away I could buy a new board and if yes, where? I need help.
Not sure, but perhaps someone else is selling a broken one cheaply near you.
Thanks mate 👍 great video and saved this getting binned
Glad it helped
I wonder if that's why this bose sound touch 300 dosent want to turn on
I was hoping someone could assist me, there are two larger (2512 size) surface mount resistors on the bottom of the board when you first remove the cover. One is marked 7R5 the other is mounted with provision for another beside it. Could someone please tell me the value of the other resistor please?
Hi, I have the same problem, but I can't find the or at least I don't know how to search. Can you help me?
where can I buy this diode? Do you sale or provide info where I can buy it please
another question, for second sub, amber light change to white led for 2 second then goes red light and goes off for 5 second, (it is cycling amber-white-red) i think it has wrong FW, How can i upgrade subwoofer FW correctly? when I look in app, it show Subwoofer 700, actually it is 300.
How did you find out which part was broken? My bose speaker goes on and off again hasnt lost power completely but i wouldnt know if its the same part or a different one?
I found out by digging around the internet for what fails on them. Your problem might not be the same as mine just didn't turn on one day. But for the cheap cost of the chip, might be best to just try it.
@@outie555two Thank You
Great Vid. I have the same Problem.
But which diode can i Use ?
I find DO-214 AC in 40 V and 60 V and 100 V. Which one i have to bye ?
Sorry for my English
100V 2Ah schottky smd
gracias por el aporte, me funcionó, en mi caso el diodo no estaba en corto circuito me daba una medición de 0.38V y en inversa me marcaba 1.8V sospechando de que este dañado remplace con otro shotcky diferente numeración respetando la capacidad de 2A. funciono.
saludos
I have this sub woofer and it makes these scratchy sounds and and doesn’t work. Do you think it’s the same problem?
I never experienced those symptoms, it just didn't turn on one day.
Many thanks for sharing your video. My bose lifestyle 600 is working. Greetings.
Glad it helped
After replacing the diode my bass module 700 worked again but i felt the sound is broken(fluttering) . Can u please suggest any fix ? Thanks in advance💯
Thanks for the video, now I know that I won't be able to fix it myself 😂
Any time! But you'll never know unless you give it a go. I believe in you :)
My subwoofer lasts 8 minutes working normally and then it turns off and starts restarting until it cools down again. Will it be the same problem? Will it be solved with that?
I don't think you have the same problem as this problem doesn't have the same symptoms. It just doesn't turn on one day.
Did yours still come on but just not play bass or is this a different issue you think?
Thanks for posting, worked a treat👍🏻👍🏻👍🏻
Another one saved from the dump
Mine just got a piece of plastic stuck in there and I can’t get it out
Hello, great video, physically did the out of service diode look burnt?
I have the exact same problem but the J401 diode looks ok
The faulty diode looked fine on the outside. You might be able to test it with a multimeter but if your speaker isn't turning on its probably that diode being faulty anyway.
Does this fix a bose lifestyle 600/650 too?
If it's got the same woofer then probably would. They sell the same woofer but with different sound bars then call the package a different number, but is likely to have the same internal parts.
Hi Sir
I have same issue, manage to disamble the unit but can’t see any damage to the chip, just a silly question can we physically able to see the damage and is it 100% this chip to replace not any other. Kind regards
You cannot physically see the damage to the chip. It's a common fault with this model and literally hundreds of people have swapped that chip out with a new one and got the speaker powering up and working again
Hw to connect to t.v. I tryed using HDMI CABLE
nice job. i have bose acoustimass 10 series iv subwoofer. all other channels working good. but subwoofer sound is not normal. working but very low sound and not pure bass. very week bass coming. how can i fix?
On the remote, press bass, the volume up.
@@outie555two it’s circuit board problem. I tried all other ways.
Can no longer pair Max Box.the status light remains off despite the Power supply.what exactly was defektive in your Box?
Trank you
That one chip I replaced was the problem, and sounds like your issue too.
@@outie555two thanks
como encontraste la falla sin tester??
Is it possible to connect by cable?
I wouldn't. There is a reason the chip is in there.
What is the price of this chip u installed plz
