Altec Lancing VS4121 speakers

I just purchased Altec Lancing VS4121 speakers and hooked them up to my computer but when I use them there is an echo or reverb that makes it almost impossible to distinguish words etc. My computer has Vista for an operating system. Thanks

SOURCE: No Power (LED off) in the Altec Lansing VS4121

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.

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.

to get 5.1 you need to have an optical/co-axal/hdmi input in to the speakers to get 5.1 and then the dvd player must have one of them as an out put

Altec Lansing VS4121 speakers stopped working for no reason????

I had a similar set and they drove me mad because they hissed when they were switched off. I bought a pair of Bowers and Wilkins MM1 instead. Fabulous.

If you want yours fixed you would have to take them to an electronics engineer or return them.

How to open the subwoofer housing to change the fuse

on the back unscrew all the screws (there should be 8 in the plastic square around the jacks... and then undo the four that are in the wooden back) then pull out the plastic square, it will take a decent amount of force, try prying with a flat head screw driver. Once you have that out, you should be able to access what you need inside.

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
