The problem that I found with the mms 171 is the sound control function knob. When I took the component apart and took a closer look it appears the unit may have over heated a bit, I found some discoloration on the circuit board. When after I played with the reluctor wheel a bit it started to work again. I'm thinking what is going on is the unit heats up and warps the metal brush and it doesn't make contact any more. A simple fix is to take apart the knob a gently push the brush back down on to the circuit board (see picture)"><a rel='nofollow' href="http://s1088.photobucket.com/albums/i325/porkchopz28/?action=view&amp;current=DSCN1604.jpg" target="_blank"><img src="http://i1088.photobucket.com/albums/i325/porkchopz28/DSCN1604.jpg" border="0" alt="NO SOUND FROM SPEAKERS - Photobucket"></a>

Suddenly no sound from speakers


First, we must determine if the problem is with the speakers themselves, or with hardware or software of the computer. Try plugging a set of headphones into the audio out jack of your system (often times, this will be a green colored jack). Play sound on the computer while listening to the headphones, can you hear the sound? If so, the problem is with the speakers, otherwise, you need to troubleshoot software/hardware of the system. Another method would be to try plugging these speakers into the headphone jack on an mp3 player, mobile cd player, stereo, or similar device. Aside from the system not putting out sound, the speakers could be plugged into the incorrect jack on the system (not audio out, OR not audio out on the correct device), or turned all the way down.

I'm not getting any sound. Speakers are plugged in but no sound. Was working a few days ago. It's as if the sound programing has been deleted.


Could you specify if it's a computer you're plugging into or a device like an ipod or stereo? If the computer isn't giving you any sound, try the speakers with an ipod or something and then you can narrow down the problem to your sound settings / sound card...

Recently, I purchased a used set of Bose 901 VI speakers. They are crackling when base sounds play. What is the problem? Was I duped? Is it the speakers or the amp or the volume. Can I repair?


It is likely that the speakers were damaged by someone playing the system at way too high a level.

If the noise sounds like a scraping, then it is the speakers themselves.
If the noise sounds like a breaking sound then it is likely the amplifier.

Another possibility is that if you are not useing a Bose amplifier, then your amp may not be capable of properly powering the speakers.

Both speakers have sound, but some of it will not play.


You have connector problems- probably bad/bent/worn "jacks" in the speakers or they may be dirty (oxidation, etc) or fatigued. If you can get to the Jack on the inside of the speaker make sure it is making good contact with the plug. Clean the surfaces using alcohol on a Q tip or cloth. Many of these type speakers are not serviceable.
