If you hook one of the other speakers to the wire for the woofer does the speaker work?

if so it is bad woofer

if not wiring is no good

there might be a circuit breaker that you push in on the on off switch or in other place

make sure if you are using speaker level connection that you are putting it in right place

it should be a line level input if this is a powered sub woofer

also there might be a volume control on sub also

be more specific on connections and where they are coming from if you need more help next time

good luck

Unable to hear system through speakers,but ok through headphones


Make certain the connections to your speakers are good. Test each of your speakers with a 1.5 battery. Put the + and - ends of the battery to the + & - of the speaker (not connected to amp). Just for a short time only - the speaker should "pop".
If they are good you might have damaged the headphone socket on the machine. These disconnect the speakers when the headphone jack is inserted. Sometimes the contacts break or become bent out of place thus not reconnecting the speakers. This can be easily fixed and is not an expensive repair. The only exception would be if there is a switch to switch off the speakers on the unit itself. But if in the past you have put a headphone jack in the unit when the speakers were operating and they cut off then a faulty jack socket is to blame.

Is there a way to use the Altec Lansing VS4121 Subwoofer as a stand alone?


Normally these low end systems components that depend on each other and cannot be interchangeable from other system. So if one of the components (sub woofer or right control satellite speaker) breaks or gets lost the whole system is unusable...
I was in the same situation. Got a sub woofer from VS4121 without original satellite speakers. I acquired satellite speakers from Altec Lansing 251 which used same connectors but the internal wiring was different and incompatible out of the box. Speakers are also glued together so it is impossible to open without damaging it. Not to mention there is no service documentation anywhere..
But if you like electronics you can try to make something based on the information bellow:
Altec Lansing VS4121 connector pinout
If you take the male connector (from right satellite speaker) and look at the pins and number them first row from left to right pins 1-3, second row pins 4-7, the bottom row pins 8-9 and the circle enclosure as 0
0 - Ground
1 - Speaker Right
2 - Treble (seems just like voltage control but may need to be confirmed: Min=0V; Max=voltage from Volume control Pin 9)
3 - Head Set Right
4 - Bass signal (not sure what the exact original design is as I have not opened the speaker) But seems like they use 50K potentiometer and some sort of RC low pass filter configuration. When potentiometer is set to Min it is shorted with ground. When set to Max it is taking signal from Right and Left Head Set (pins 3 and 5) combined through some larger resistors and low pass filter.
5 - Head Set Left
6 - Ground for Head set (grounds 0 and 6 seems to be connected in the subwofer but within the right satelite speaker they seem to be isolated with separate leads to sub)
7 - Power ON/OFF. When OFF or head set jack plugged = 0V; When ON and head set jack unplugged = 5V
8 - 5V Power in
9 - Volume (min=0V; max=5V). It seems they use 50K potentiometer but probably anything >10k should work.
At minimum for standalone sub woofer you will need to implement:
- Power On.Off (switch between pins 8,7)
- Volume control (50k potentiometer (probably anything beteen 10k and 50k will do)between pin 7 and 0 with variable output to pin 9
- Bass control - join two resistors R (I used 7k) and lets call this join point A. Attach other ends of the resistors to pins 3 and 5 respectively. Attach 50k potentiometer (I used 10k) between point A and ground 0. Attach Variable pin of the potentiometer to pin 4 (Bass input signal). Attach capacitor C between Pin 4 and Ground pin 0 (I used Electrolytic 1uF with negative end to ground) . Resistor R and capacitor C should make simple passive low pass filter (Google for formula) that should bypass anf frequency higher than 80-120Hz to ground and feed frequencies lower than 80-120Hz to pin 4.
PS: I managed to hack 251 control satellite speaker to somewhat work with VS 4121 Subwoofer but that is another subject. All electronic parts were salvaged from old broken TV so total cost was $0 but took several days of tinkering for speakers that I could buy used for $10-20 :)

Dv7 subwofer is missing so speakers and headphones dont work. Do i need a new subwofer?


Generally speaking, sub-woofers are not built into notebook computers, as most sub-woofers would not fit. However, there are generally speakers, and there tend to be problems with the audio drivers in most cases if there is no sound for both speakers and headphones.
Within the notebook, there should only be two speakers. If they're missing, did you buy this used or refurbished? If someone just yanked out the two speakers and carelessly cut or handled the wiring improperly, then this could interrupt the headphone bypass cut-off.
I know you mentioned you'd already verified everything appeared to be working properly, and in some cases updating drivers or uninstalling and re-installing them has a positive result. For the obvious, which I've also forgotten to check sometimes, is whether the output is muted within the volume control and mixer.
In case you hadn't already checked out these, here are a few links you may find useful:http://h10032.www1.hp.com/ctg/Manual/c01613382.pdf

As always, the more complete the information up front, the better the potential for a solution. I hope this helps!

My altect lansing bxr1121 speakers stopped working suddenly. I have checked all the connection but the power led is off.


Hi. i think it is the internal connections or jacks need to be resoldered, but first try to check the continuity of each wires. tact switch cleaning and replacement is another approach.

My Kenwood amplifier is having problems, whenever i turn it on. all seems well until i play some music through it, after 30seconds to a minute the music will cut off and a distinct click is sometimes...


Your amp is going into protection. The click you hear is a relay meant to protect your speakers and stereo. Check your speakers with an ohm meter for the the proper ohms ( listed on the speaker ) and physically try to push each woofer and midrange cone in gently to make sure it moves and is not stuck or frozen in place. A speaker may read correctly on an ohm meter if the woofer is ok but if the tweeter or midrange is not working it will cause the amp to go into protection mode. When you play music stick your ear up to each tweeter\midrange\woofer to ensure they are working.
Your stereo could also be the culprit although usually if it plays music it is ok as long as you are not hearing loud pops. Loud pops are voltage spikes that indicate that a transistor\IC is breaking down and will eventually short. Good luck!
