Broken speaker My 6 year old son pulled the speaker with the volume control on it and the wires pulled out. my husband tried to fix it but despite his efforts, none of the speakers will work. is there an alternative way to hook it up so the subwoofer and other speaker will at least work?

You need to open the subwoofer box and see what's the wire pulled and you need a soldering iron..

The only way is o replace the wires from end to end.. you may have to do some soldering inside the subwoofer and the satellite speakers

I am going to guess these are fairly old speakers. I would recommend getting a replacement system.

Static when I turn on speakers or adjust volume


The problem is that the switch/volume control is dirty.
This is what I have done.

Dismantling Altec Lansing VS 2221 speakers to clean the switch/volume control


Tools: a medium Phillips screwdriver, a craft knife & a can of CO contact cleaner & extension.


1. Remove switch/volume control knob by pulling it off

2. Pull out the base for the stand if attached

3. Unscrew the 2 screws beside the wires

4. Remove the front gauze by prising it out from one of the bottom corners. Keep the gauze straight as it will need to be put back from the bottom to the top.

5. Remove the 2 screws at the top and the 4 long screws holding the speaker. The back will come apart from the front and sides. If it has been glued then use the craft knife to carefully cut the back away from the sides and/or prise it away with a little pressure on the sides.

6. Attach the extension to the can of contact cleaner.

7. Lift the circuit board out and squirt only the switch/volume control. Ensure you squirt the shaft and the internal parts of the switch/volume control. Turn the shaft a few times.

8. Allow the contact cleaner at least 1 hour to dry.

9. Test the speakers. If the noise is still there then repeat steps 6-9.

10. To assemble the speaker do the steps 1-5 in the opposite order.

I hope this is helpful

Broken Volume Control


try ebay or bizrate
it may be easier than you think to fix it.
look for a new cable or a similar end piece and you can splice the new cable onto the old one.
if you would like when you get a new cable i can assist you step by step to fix it.. you will need to get electical tape and wire cutters/strippers

Creative Inspire 5300 Volume Control broken!


For those searching the answer "How to replace/repair Creative Inspire 5300 volume control":

Its simple : looking at the back of the suboofer, the pins are as follows from top right, clockwise : LED VDD , Balance pot middle leg, GND, pots + legs, Volume pot middle leg, on switch input. Connect one pots ends to GND and the other ends to pots +, connect a switch on GND and on switch input, anode of led to LED VDD, cathode to GND (there is a 1,8k resistor inside so no external resistor needed)

Need wiring and 9pin connector diagram


Dell (Altec Lansing) A425 Subwoofer Pinouts

This is a standard female DB-9 serial port.
Here are the pinouts.

Pin 1 = Left Speaker Out +

Pin 2 = Left Speaker Out - (Common Ground)

Pin 3 = Left Line In +

Pin 4 = Right Line In +

Pin 5 = Left/Right line In - (Common Ground)

Pin 6 = Right Speaker Out +

Pin 7 = Right Speaker Out - (Common Ground)

Pin 8 = Power A

Pin 9 = Power B

Jumper (short) Power A to B to turn on.
If you want a volume control you need to put one on the inputs. You will buy buy a stereo volume control or potentiometer.
Here is some info on how to do this.

Multimedia speakers not playing up to potential


After I posted my problem, I browsed a bit further through the other posts and solutions, until I came across the excellent solution of TrickyTrev34 and gave it a try. However, I did not slice the cable, but did it as follows: <p> 1. Switch off power of the sound system on the subwoofer box. Disconnect the Front Right (FR) speaker box (the one with the volume control) from the subwoofer box.<br>
2. Remove the silver coloured metal oval on which the speaker box stands. Now you'll see a small screw at the bottom of the speaker box. remove it.<br> 3. Carefully remove the silver coloured metal protection plate (with all the little holes) from the front of the FR speaker box by wedging it from the top with a flathead screwdriver or other thin blunt object. Now you'll see the speaker and 4 holes with screws inside. Remove screws and speaker box opens up..<br> 4. Inside you should see six wires (Red, Blue, Yellow, White, Green & Black). Carefully cut the GREEN wire only. Insulate the both ends of the GREEN wire with electrical tape or heatshrink or similar.<br>
5. Put the FR speaker box back together in reversed order.<br> 6. Connect FR speaker back to the subwoofer box. Make sure the volume setting on your PC is very low, because when you switch back on the power of the subwoofer, you should be blasting again.<br>
<p> As TrickyTrev34 already mentioned, the only downside of this procedure is that it will disable the volume control on the FR speaker, but who cares, your sound system works again, and you can still control the volume via the PC playback control panel and/or the multi-media keyboard if you have one.<p>Thanks for giving the lead trickytrev34.

Limited volume on speakers. Worked well previously.


Guys,

In case my nickname does not show, this is treefarmer. I had the same problem and decided to fix it myself over this Christmas. I was successful, and here is what I found.

In my case, the problem lies with the volume control chip ( it has a voltage controlled amplifier, or VCA in it) on the main amplifier board. The voltage which controls the volume for all channels comes from the right front speaker. There is an issue with the I.C., in that it has some abnormal loading (leakage) of the volume control signal at the I.C. pin. You need about 5.2 volts for full volume output, and on my system, I can only get about 1 volt. You can find the IC data sheet (Mitsubishi M51132L) here:

datasheet.html">http://www.datasheetarchive.com/M51132L-datasheet.html

The parts inside the enclosure get quite hot under normal operation, and I would not be surprised if this I.C. has an issue with degradation under high temperature. Regardless of the problem, I managed to get the volume back with one simple fix.

If you can open up the right front speaker, place a 10 kohm resistor in parallel with R1, which should have three orange stripes, and one gold stripe. This fixed mine, but this might only be temporary, depending on how much worse the volume control I.C. becomes.

I did check out the power supply, including transformers and everything else, and they all look fine. It would surprise me if the transformer failed as has been posted in other forums. They should be able to survive higher temperatures than the other electronic components in the box, especially when most of them are consumer grade parts with a max temperature of 70 C. One thing of note is that turning off the right front speaker pretty much shuts off most of the quiescent current draw of the amplifier board. I found that with only the sub cabinet switch on, nothing gets warm. You won't see significant warming of the interior components until you turn on the right front speaker. However, then the inside of the sub enclosure gets pretty hot (too hot in my opinion) just sitting there with all the speakers powered up.

I would recommend at least turning off the Right Front speaker when the computer is powered down. More often if you are not listening to anything. I don't think you need to shut off the sub enclosure to keep things cool, but turning off everything ensures that the amp is not sitting there cooking itself. And, unless Altec has changed the design, I would bet new systems will fail in the same manner.

For what that's worth. Hopefully somebody will find this helpful

Volume control on the master speaker


If its a rotory type control simply take the rest out or off the pcb if you can and on the side of almost any varable resistor or pot is a value. Look to see if radio shack has that value or check your local electronic parts supply house and solder back into place But you may not get the exact one as they all have differant mechanical standards as the shaft may be too long or it may not fit on the pcb so you will have to drill into the cabinet and mount where theres nothing in the way and hook the wires to the control from where the old control was. Hope this helps good luck
