Can I get the circuit drawing for labtec speakers LCS 1050

SOURCE: LCW-0120 Labtec speaker polarity

I am assuming that you already know which wires go to which speaker and all you need to know is which one is negative and which one is positive. Here is one way to find out. If you can access the speakers at all or at least see the cones, it will be easy.
Take a small 1.5v battery and connect it to the wires in question, connect one end to the positive(+) and the other to the negative (-) side of the battery, don't do it for a long time, just enough to observe movement on the speaker cones. Observe the cones of the speakers, if the cones get pushed or moves out, take note of the polarity of the battery because now you know which is which. Now if the cones, move inward or it gets sucked in when you apply voltage, then it's backwards.

check whether the output plug is connected properly or not.... if it is then check out whether the adapter is giving the power output.... if it is then the speakers are spoilt otherwise u can just replace the adapter...

SOURCE: installing Labtec LCS 800 speakers

1 wire goes between the 2 speakers
1 wire goes from the speaker with 2 jacks in it to the computer, the back of the computer should have a green port to plug in the cable to
1 wire is the power

this is a guess without seeing your setup

I have the same problem sir, only the speaker with volume
control works. Earlier I used to twist the volume control this
way and that way to get the sound from the other speaker also.
Now the same technique doesn't work anymore.
