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 .

My sound stopped working except the sub and amp.


If you have a little electronic know how... it can be a blown capacitor in the speaker. If you find it, solder a new one in and turn the volume down in the future. And look around for any signs of burnt insulation. Trunk amps are notorious for being insufficiently wired for power.

Change main fuse but still not working right


First of all, nothing wrong with the fuse. A fuse is nothing but a short piece of wire with a resistance value. If the unit turns on, fuse is fine. The fact that the headphones you plugged in are working tells you that the music is finding it's way up to that point. You must realize that the speakers themselves have additional circuitry that the headphones don't use. If you could obtain a diagram for the circuitry you might find that a capacitor or a diode or a transistor got "zapped" when the high voltage was applied.
If you have this diagram and you don't know what component is defective, can you post that diagram and I would be glad to help!

No sound out of Behringer BXL3000 speaker


Suspected Faulty PC board Dead Capacitor Or Mod Pot I would suggest returning it for an exchange the problem is your speaker will work on a regular stereo because a stereo powers the sound internally causing the magnets in the speaker to vibrate Headphone jacks are designed to pick up off a seperate circuit board with a different connection to the main board hence the no sound from the speaker.

Tin like sound from small speakers only. No sound


switch on your speaker set in full volume unplug it from computer touch the plug , as you touch you can hear a sound ( loud hum sound) if the speaker is working. If okay then check the right jack, plug it into green color jack. you can try if your computer is okay use a headphone plug it into the jack in PC , if the computer is okay you may hear the sound.

I have a hp pacilion dv 1000 and i have no sound on my speakers but when i connect the headphone i do get sound what could be causing this problem can someone help. ty


the headphone jack has dual contacts per side in order to re-connect your speakers when you pull the head phones out....these contacts might not be contacting each other so your problem would be the head phone jack...replace the jack...of course this is assuming that your speakers are working.
good luck

Toshiba A10 headphone jack problem


I think you are on the right track, if the headphone jack is worn and shorting out itll kill the speakers because it thinks headphones are plgged in, ebay would be a good start for parts, maybe even call toshiba and speak to their tech support.
