Dim Light on Control Pod...very low volume output

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.

    On the companion 3 everything runs through the subwoofer box (power, audio line in, satellite speakers, and the control pod). So its not really possible to disconnect the sub.

  • johntolfa May 17, 2008

    Same problem. Indicator light is dim/ green and volume is low and cannot be changed. touch sensativity to turn on and off does not respond.

  • tentpop Jun 18, 2008

    My Companion 3 decided to not work today. The LED on the control pod is very very dim and the sound is barely audible. I tried it on my ipod and the same thing. Does anyone know what the solution is?

  • donnaym Sep 13, 2008

    I have the exact same problem. Since the unit is out of warranty, I would like to know how to disassemble it.

    Having same issue and there doesn't appear to be a solution anywhere. Very disappointed as I am a Bose dealer!

  • pukstershopp Nov 15, 2008

    Same problem here. I contacted Bose a year ago and they suggested a new control pod, so I bought it. Now I have 2 control pods for a broken unit. Bose sucks! And of course, it was a month out of warranty when it happened. Sounds like planned obsolescence.

  • rcandle Mar 18, 2009

    I have the same problem: dim indicator light, no response to touch, low
    volume output, no volume control. I just ordered a new control pod,
    but others are saying this did not work either. Everyone is having
    this problem. These units must be defective. Can we sue Bose over a
    mass defective product?

  • Anonymous Mar 25, 2009

    Same exact problem

  • Anonymous Apr 21, 2009

    Yep just happened to me 2 days ago.. Verified all connection 5 x and everything is tight. Moved entire system to another PC and got same results. I can hear the sub turn on/off, but other than that ...silence...VERY dissappointing..

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

    Could you give more details..... a fix-it step-by-step for that would help get us up and running. Thanks.

  • dragon_67 Dec 04, 2011

    Just replace the transistor just above the capacitor marked c313 on the main PC board. Use NTE123ap if you can't find the exact one.

    I have the same problem. Do you have a diagram showing where is c313 located on the main board?

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 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!

My thoughts on this issue is that the amp for the sub is possibly going to protect mode or is entirely shorted causing the load on the rest of the unit. If possible unplug the sub from the rest of the unit and see if it lights up like normal.

    The two reasons then is either a bad output for the amp or something in the powersupply. These units are mostly sealed with goop of some kind so there really hard to repair but its possible, i would bank on getting a new system.

Control Pod for Bose Companion 5 speaker system

I had the same problem right out of the gate, the volume dial on my control pod for my Companion 5 wasn't working, however, the touch pad and LED worked. I called Bose customer service and was instructed to:

First, unplug the power directly at the back of the woofer while the unit was on;

Next, I was instructed to unplug the control pod, visually inspect for any damage/defect;

Finally, re-seat the control pod on the back of the woofer and then lastly plug the power cable back into the woofer.

It worked like a charm. I hope this is helpful!

Bose companion 5 problems

Have had Bose companion 5s for about three years. The external volume deveice in not active. If I unplug it, the sound goes dead. The indicator light is stuck on green and is very dim.. The touch feature does not respond nor does the volume. Sound is set very low an barely audible. Can I get replacement external volume control or is the problem inside the base unit itself? Any help out there with a similar problem.

Thanks JT
