Bose Bass Module 700 not working anymore

Question

Hello,
Could you please help me...
For more than 2 years, my bass speaker 700 has been paired with my soundtouch 300 and there has been no problem... And today I realize that the speaker is not working... Even when plugging in the jack 3.5 cable... after the update nothing changes... The indicator light at the back of the speaker is not working... I have unplugged it for a long time but nothing helps... Please help me?

Configuration: Android / Chrome 88.0.4324.93

Hello community. I contacted the Hifi store (specialized in Bose) in my town and the salesperson told me that the problem is very, very, very well-known with Bose subwoofers and that it comes from a diode or a bridge of diodes.
I searched online and found a video explaining which diode it is (reference B2100-13-F) and where it is located on the circuit board.
Here is the link to the video (in English): https://www.youtube.com/watch?v=jTvNLRxT8iU&feature=youtu.be
The diode costs <1€ and seems easy to replace. I will try it, it will save me a hundred euros... I will let you know if it worked.
See you!

Hello and welcome to this forum,

If the light indicator doesn't turn on at all, we can hypothesize a faulty power supply, check if a fuse has blown

But you’re welcome, and I was thinking about a potential fuse inside the box  -- I call a spade a spade *      *in French in the text

hello, did you finally get the enclosure repaired? if so, what was the cause of the failure? (I have the same problem...... indicator light off...)

Good evening "Brocboeuf", I have exactly the same product and the same problem, where did you get your subwoofer repaired?

Astonishing, I too, my subwoofer has failed. I bought it on amazon.it and on the Bose.it website they tell me that they cannot handle the repair in their country. I looked on the Bose.fr website, and they tell me the same thing. What should I do?

Absolutely great, I found more videos discussing it, I'm not even going to send my subwoofer to Bose but rather take apart the circuit board, bring it to an electrician with the video and the diode reference. https://www.youtube.com/watch?v=vQSv2j2OB3A&feature=youtu.be

What’s crazy when you watch videos on YouTube and read the comments is that the problem always seems to come up after about 2.5 years.
Finally, the Bose community (official forum) has been closed, and it’s difficult to find information on Google.

I was able to obtain a free repair beyond the Bose warranty, proof that the issue is known. They did change the diode.
In the meantime, I had bought the diode which I keep safely in case the problem resurfaces.
This resembles a hidden defect and in this case, the warranty is 5 years for this kind of issue.

Arno · Answer

Good evening, I’m in the same situation...
No more orange diode.
How did you manage to get a Bose support even though the 2-year warranty has expired? The subwoofer is from December 2017, so it's a little over 4 years...
Thank you for your help!
