Question about Bose Companion 3 Computer Speakers
I've had the series 1 companion 3 for almost three years when one day I noticed the sound just stopped playing. Upon examination, it didn't stop, but played very quietly from the satellites. Also the indicator light on the control pod went to about 1/4 brightness (whether green/on or orange/muted). The volume works but goes from very faint on the low end to faint and distorted when turned all the way up. I tested it from multiple sources (computer, stereo, ipod, etc) and I get the same thing each time. I took it to a bose-authorized repair shop and was told it was most likely a faulty control pod. So I ordered a new one from bose ($35 w/ shipping) and there was no difference with the new control pod. Any thoughts?... I'm thinking it's a power issue with the subwoofer box, perhaps a bad fuse...but didn't want to open up the box if I didn't have to. Thanks.
I just fixed this exact problem. There is only 1-2 volts feeding the preamp IC's pin 4 JRC 2059. Positive side of C313 should be 12v(B+ to IC's) found shorted transistor just above C313. Collector goes to V+ 15v from power supply, Emitter feeds the preamp IC's. I used a 2sc3904 (NTE123Ap) unit back up and running

To take apart the subwoofer for Bose Companion 3, peel off the label on the back panel to reveal 4 more screws that need to be removed. Then you can pull out the circuit boards

Back in June this problem happened. I did open up the unit to see if I could pinpoint the issue. That didn't work. I called Bose for help. What I was told but haven't followed through on it yet was this:
Bose said that I could send it to their repair facility and have it fixed for a flat $75 fee. That sounds reasonable since the unit is a couple of hundred dollars. If someone does try that before me, let us know what the outcome is.

I took mine apart today to check for obvious issues that could be causing the dim light and low volume... loose connections, exposed wire, or blown fuse. I disconnected the speaker, the amp, and all wiring inside and then reconnected. The fuse was not blown, although it is not one that could be easily replaced if it had. The wiring was not loose, nor did there appear to be any visible short. I put back together and tried to turn it on again... same effect. Looks like this will be my first and last Bose purchase.

I can not help you with your problem, but I can help you get rid of your extra control pod if you wish. My cat ate the wire on mine and now I have no sound at all (actually, I find your story quite annoying, I hope I won't have the same problem in a few months...). You can contact me at firstname.lastname@example.org and suggest a price for it.
And good luck with your problem!

My unit recently developed the same issue. I went ahead and ordered a new control pod and that didn't work. I tried to disassemble the unit in order to determine if there was any issues, but like other users, could not get the back off. Turns out that wouldn't have solved the problem either. I'm very disappointed. Loved the quality of the speakers and hate that they gave out within 5 years. Boo!
