Altec Lansing VS 4221 Right Speaker crackle

I have hooked up new speakers (2 and a subwoofer) to my TV using the green headphone jack and its great all except for a cracle noise interference on the right speaker. Any suggestions. I know I could use the RCA lead with an adaptor but it should not be cracling now right?
Hope you can help me.

First of all take a headphones and connect it to the TV and listen the sound.If it is OK the problem is or the cable or the amp.You probably have two RCA connectors on the cable red and white or black for input of the amp.Connect the cable to the tv again and change places of the RCAs (red to white on the amp and white to red).If cracling is now on the left speaker buy a new cable but if its still on the right you have problem with the amp.And you are right if everything is OK it shouldn't be cracling.I hope that this will help you

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 :)

Hooking 5.1 computer speakers to a Samsung Plasma


Computer speakers are powered, they have their own amps inside the speaker cabinet.

To get these to work on a TV you need to plug them into a headphone out jack.

The external speaker terminals produce too hot a signal for powered computer speakers. The amp in the speakers may have already been damaged.

Cannot connect my surround sound altec lansing system to my compu


The first thing you can do is go to www.retrevo.com to download the manual. Secondly all you have to do is match the colors of the wires to the imports in the back. You have five speakers. Two have gray wires, two have red and one has blue. If you also notice each speaker has two wires. One a solid color, the other striped with black. For instance, put the solid red wire into the red import and the red wire with the black stripe into the black import. Repeat this with all the other wires. The easiest way to hook it up to your computer or laptop is to take one of the aux wires (the wires with the yellow/green/black tips). It doesn't matter which one. Put into you headphone import on your computer or laptop. Then put the other side into the Aux on the subwoofer. Located on the front. Turn on the power on the back. Then hit the aux button on the remote. That should work....

Altec Lansing VS 4121


It is unlikely that this is a problem with your speakers more likely that it is a problem with the DVD player itself. I would recomend trying another DVD player.

No sound from the right speaker


Check the speaker if its okay, disconnect the left side one and connect the right side one and play. If it does not then the speaker is bad.
