Anyone happen to know what the exact failure mode is? Is it a Rifa?

Re: Bose recall on several older Acoustimass, Liefstyle, Companion model subwoofers?
no, from the description i would suspect something like bad soldering on the mains inlet.
that's what caused the original xbox fires - they changed the mains inlet after that.
it could also be a bad arcing power switch but they are usually loaded with bromide to prevent combustion. -
Re: Bose recall on several older Acoustimass, Liefstyle, Companion model subwoofers?
if it were a power switch it would have been used on other devices and there'd be more than just these? But soldering is possible, curious if anyone knew exactly what fails and what can be learned from it...Comment

Re: Bose recall on several older Acoustimass, Liefstyle, Companion model subwoofers?
Thanks for posting this here, eccerr0r.
The people who are currently staying (temporarily) in my parents' house have a similar Bose system. Not sure if it's an Acoustimass, but it's from before 2006, IIRC (I set it up for them and noted it looked quite dated.) Won't be able to get a chance to take a look at it until at least a few months or more from now, but it's good to know. Hopefully I remember to check which one it is... and if it's one of the affected models, to open it and see what the issue might be.
Given the recall failure appears to be on units that are over 15 years old now, I don't think the issue would be a switch or a plug. More like insulation failing somewhere or perhaps another case of the conductive glue biting back at us?Comment

I picked up this used Bose Acoustimass 10 IV speaker system. Speakers seem to work fine, but the subwoofer does not make any noise. So I took apart the unit and found some obviously failed (burnt) components:
- 1x 3.14 A @ 250V main circuit fuse
- 1x bridge rectifier GBU601. there's actually two of these on the board, one is obviously burnt and the other does not seem to have any anomalies like shorts. However I figure may as well replace both.
- 2x diode. This is tricky because the only markings I see on it are: "617 402". No current rating or anything else.... -
Hi guys,
Trying to salvage a Bose Companion 5 computer speaker system that powers off shortly after powering on. It's got a primary USB input (built in DAC) and an aux 3.5mm input. The USB appears to be the primarily source that tells the unit to power on (control pod LED goes green) as the unit has no power switch.
When I first connect power to the unit, plug in the USB, it will play audio nicely for a minute before it drops out and the unit appears to go into standby (control pod LED goes red). It stays in standby and I cannot seem to power it back on without physically...02-03-2022, 11:14 AM -
Howdy everyone!
I have a SUV with a Bose audio system and I'm considering either a system upgrade, or purchasing a complete replacement system while bypassing the integrated Bose system.
On the Bose side, I have not found any specifications yet. It's a decent system but I'm, at a minimum, replacing all the factory speakers, head unit and adding an amp and two 8" subs. The Bose is a 2ohm system and I'm not certain about this point. In order to use a 4ohm set of speakers (component/loud), I would need to install 2 sets of 4ohm speakers wired in parallel to match the... -
The device has no Orange or Green LED when power plugged in. I've checked the famous DIODE issue - it's good, I've replaced it anyway - same issue. I've attached relevant pictures and measurements for reference. If you need more details - let me know - what do you recommend I check next?

My dad gave me his bose soundlink color 2, claiming that the charging port was loose. I opened it up, plugged it in, probed around with a multimeter, and I can measure 5V all over the board. I wiggle the charging cable around, no change. The port looks fine: sturdy, clean contacts. I measure across the battery wires and I get 0V, so I assumed the battery was the problem. But then a few minutes later after I disconnected and re-connected the daughter board with the buttons, lights were flashing and I was reading 3.3V across the battery wires. The only logical explanation for this I could come up...12-12-2024, 03:20 PM
