Question about Altec Lansing VS4121 Speaker

No Power (LED off) in the Altec Lansing VS4121

I have an Altec Lansing VS4121 Speaker system. Recently, possibly due to some voltage fluctuation, something has gone wrong with the Speakers and they dont power on anymore. LED light remains off. I tried looking into the circuit to see if a fuse was blown and I managed to open up the woofer, and see the internal circuit, trying to trace the flow of electricity. It seems that there is voltage flowing into the right Satellite speaker. But I cannot manage to figure out how to open up/disassemble the Satellite speaker. Does anyone know if there is a fuse built into the Speakers which may have blown. Or anybody ever managed to disassemble the Satellite without damaging it?

    Thanx for the suggestion.

    But I actually already checked the fuse on the power supply board inside the subwoofer case.

    The circuit inside the Subwoofer case seems fine to me.. I actually checked it out with a multimeter borrowed from a friend :D

    I see voltage flowing into the right satellite speaker... which houses the controls and on/off switch, so I thought there must be some minor circuitry in there as well...and want to check that out.

    But I cannot manage to figure out how to open up the right Satellite speaker without damaging it... cant see any screws :(

    and I dint apply too much pressure..

    The problem is I dont have an authorized Altec Lansing dealer around here... and I would much rather check out the basics myself before handing it over to another technician.

    Appreciate if anybody can help me out with this.

    Thanx

    Where are the four screws securing the power supply board? No visible screws on the control unit. The main speaker has one 8 screw panel into which all cords go and four screws which don't seem to gain access to anything inside.

    It is actually attached by adhesive,it has no scew..so you need a thin metal then dismantle from a side by penetrating the metal slowly to the whole round and it will open very easily
    Thanks

There is no way to open the satellite speaker without destroying it. I tried and found that the whole thing was glued together. Mine is now destroyed

    To open the main sub woofer u need to open the front grill and then open the speaker screws first. To open the sattellite speakers just slide in a sharp tool from the side.

If your VS4121 units have lost power, then why not convert them to unpowered small speakers. The small cable speaker has a red/black that when spliced creates your Pos/Neg to use. Now the large DIN cabled speaker, once spliced has 10 wires to chose from. I found that the GREEN (Pos) and the silver BARE wire is the Neg. Bingo! New life for these little units...

There is a fuse on the power supply board which is held in place with 4 screws. Yiu will have to unplug the sub-woofer connector to remove it.

Umm I have an altec lansing vs4121 and the subwoofer is kinda loose so if i get stong bass i hear this extra vibrate in my speakers which is really annoying....


Umm, so what's the question? The sub COULD be damaged or it could be reacting to being overdriven. Sometimes resonances form due to room- or nearby surface interactions. Try moving the sub a foot or two in each direction. Or turn the bass down.

My altec lansing vs4121 speaker have to much bass with several mp3 files, waht ca i do


If it's only certain MP3 files you might want to identify WHY those files have too much bass. THAT would have happened when they were created. It's not a speaker's fault how the music sounds. Then there's your PC or whatever other device it passes through. Lots of opportunities for MALadjusted sound. GIGO.

Is is possible to install altec lansing speakers


It is possible to hook up these speakers to a laptop according to this brochure:

http://www.alteclansing.com/images/spec/vs4121%20sell%20sheet.pdf

Now this manual shows those speakers being hooked up to a computer but laptops have the same outputs as well so here it is:

you'll need adobe reader to read the manuals.

Static but no music from the satelite trebble speaker


Try to reconnect all the wires, the problem seems to be with connection. Instead of spending lot of money on speakers, you can buy just the wires, they are pretty cheap. Hope this helps.

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.

Vs4121 altec lansing left speaker wire ripped.


Black should be ground and red is usually the actual audio cable. If you connect them wrong the should not short. They will just sound weird until you connect them properly.

Hope this Helps
