Opening Labtec speakers type LCS-1030

These are speakers and do not require drivers. Your computer's sound card does require drivers, though.

Try swapping the left and right speaker wires. If the left speaker now starts working, then your amplifier is the problem.

Hi,

Good day. In response to your issue, you might need to reinstall the driver for your speakers this will correct any problem on your audio if it encounter any error and just restart the computer to finalize the installation.

Note: some software can cause conflicts with other software better check the compatability of every device or software that you plan on installing on your computer. You can check the guide or manual for this informations

Hope this help you a bit. Have a great day and thanks for choosing Fixya.

On the back of one of the speakers, there will be 3 plugs; a green one, a grey one, and a black one. The black one is the power plug. Right below the power plug it says the voltage needed (I could only find one picture online, and it looks like it says 15v, which would be 15 volts). That number is the needed supply voltage, so search google for (number under plug) volt power adapter.

Yes

If you can get the speakers open, check for blown capacitors or puffy capacitors. If you see any they will need to be replaced with capacitors with the same UF rating and at least the same voltage and make sure you line up the striped line with the striped line of the motherboard. You'll need to be able to undsolder and solder the caps off and on.

If you see big black marks on the board then the board is basically usueless cause it would cost more to fix then the cost of the board itself. Also check for any blown fuses and if there is you would need to replace them with the same rating.

I know this is a little late, but the power supply that these speakers use appears to be 5mm across. The output specifications are 15V DC, 1000mAh (1A), with the center pin being negative.

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.
