Question about Bose Acoustimass 15 System

1 Answer

Headphone jack works, sub fuse good, no sound to speakers

I had the notorious C19 33uF capacitor failuire which caused my display to die. I replaced with a 33uF 63 volt (as opposed to original 25 volt) Display working great, headphone jack works fine, now I have no output from my sub at all. Fuse is good, FETs Good, Power transistor may be suspect, I have the sub in 100 pieces and I really havent found a thing. Someone mentioned Crystal? Where is it on the board? This forum is Great! I have never seen so many experts, I know I can fix this with your help.

I gave a very long and detailed response to this but i didnt submit it correctly so its gone now !
sorry about that,
bottom line was......, it is probably your audio source.
please try a different speaker or audio source .
watch out for air leaks and rattles putting the bassbox back togther. or it will sound rubbish .

How should i connect my subwoofer- is it directly to the speakers or amplifier?t


I'm assuming that you are using a standard amplifier with L and R speaker outputs if a stereo Amp.... or L and R and SUB standard RCA output jacks. If it is a more complicated setup, having surround sound speaker jacks, then look for a SUB OUT jack or plug.
Some Subwoofers are self-powered, having their own, built in amplifier especially designed for that model. Sometimes they require a SUB connection and a power supply to the 110V AC house power too. These sometimes need a connection to a standard 3.5 mm HEADPHONE jack output plug. If it's this type, then the front of your amplifier could have one. Either way, the musical signal from amplifier to the subwoofer must be available on your Amp AND be received by the type of subwoofer you are using.

What are signs of a burnt out coil in sub


Check the bronze-colored coil underneath the foam cover. Note whether it looks worn, burned, warped or distorted. This may be the cause of your sub sounding fuzzy or muffled, which means it needs replacement.
Look at the fuse inside the speaker and test it if you know how. This is a likely problem that causes your sub to power up improperly, play sounds at about half the volume or intermittently fade in and out. If the fuse is discolored or shows a short, you'll need to replace it

I hooked up the speakers to the back of the PC with the matching green plug in. The speakers are on and working but no sound is coming out. I also clicked on the speaker icon and turned the volume all the...


The first thing to do is to determine if it is the speakers or the computer that is having issues. Plug the speakers into an MP3 play, disk player or some other audio device that has a headphone jack and verify they work. If they do, then you need to determine why the computer is not sending sound to the jack. When you right click on the speaker icon, and select "Open volume mixer" there should be multiple sliders to turn up. Make sure the internal speaker/headphone jack volume is up (and mute not selected) as well as the "applications / windows sounds" volume. comment back to me if you require further assistance and if so, include the model computer and operating system in your comments. Good-luck - Subdriver

to make sure its not your reciever unplug sub from pre out side of reciever and with sub on run finger over the tip of the RCA you should get some kind of electral feed back from it through your sub if not then your sub or the amp inside is most likley fried if you know how to open the sub and can access it you may have a mini fuse inside that can be replaced but make sure consult somone about that and not just take my word

No sound from creative t3030 2.1 speakers


the circuit board and amplifacation supply inside the sub are blow or shorted out.thus preventing any sound. the head phone jack works only because it is a bypass feature supported by the actual computer not the surround sound unit

Infinity Entra Sub 150 no sound or power


I had the same problem. When I opened it up, the fuse was blown, and it was a pain to find the fuse it needs (3 Amp, 250 V slow-blow fuse, 5x20 mm). Also, the 2 large electrolytics (big purple things near the amp) and one small capacitor were all blown. For 4 fuses, bought seperately from, and the 2 electrolytics and 1 capacitor, it cost about $20, plus almost 20 more in shipping, which still isnt bad considering the original price of the sub. However, the tricky part is that you have to know how to use a soldering iron to take out the old components and put in the new ones.

Subwoofer eating fuses.


Check the circiut board for any blown capacitors. Sometimes it's that simple as replacing a capacitor. But then again, what is causing the capacitor to blow??/ Hope this helps.
