Question about Bose Companion 3 Computer Speakers
How old are the speakers, how long have they been in use? Possible fault can be the power supply of the speakers, in these it might be internal, inside the sub.
It is most likely a power supply issue, the speakers don't wear out like a power supply does.
could be bulky or leaking capacitors inside, you might want to take it to a electronics repairer, might be a simple fix.
Or you can of course take it apart yourself, take a good close look at the caps and if any of them are not flat, replace them, with same voltage rating caps, preferably same UF rating, a bit higher is OK.

Bose® products are covered under limited warranty for at least one year from the purchase date. Please refer to your Bose owner’s guide for specific details. If you are under a year you are in good shape, can you try these on another acoustimass, it sounds like a wire came off to me. If there are any fuses that you can change do that first. Last resort is to open the module and check to see if all that tapping somehow loosened a connection or a wire came off. Please use extreme caution and unplug everything. If there are resistors , capacitors or diodes in that controller, thay shouuld be checked obviouslly something blew or is intermittent. If you know how to use and have a voltmeter check the resistors and the capcitors. If not just rplace them. Radio shack has all the components or a local electronics store. I fixed a 2000 dollar Samsung LCD, "mine" with 5 dollars worth of capacitors. if you need any advice or help I will pull up a shematic f the system and take a look at it, I just wanted you to have someting to start with, beng a holidat weekend, I am sue it can be fixed, and it seems it's a common problem with that system thus the one year warantee indtead of their usul 5 yr,thanks, Gymowner, keep me in the loop I will be around all weeekend

If the Control box you described is lit faintly, There may be problem with the power unit of the speaker system. It may not be receive/ giving the right voltage to power the control board on the speaker. Let an experienced technician look at it I assure you your speaker will work again

The sensor switch inside the speaker's headphone jack may have been stuck up in the "ON" position. I had the same problem with my speaker and I had to stick a pin and wiggle the jack sometimes it works but most of the time it is annoying and I couldn't find a replacement part to fix the problem.
