Question about Labtec LCS 2420 Computer Speakers

Not turning on.

All of the stuff is plugged in correctly and everything, but for some reason, the speakers won't turn on. I can't think of any reason they would randomly stop working, but they did.

I have these speakers and I had to dismantle the circuit board to replace some components. I think it was capacitors, but a long time ago....so...I don't remember which parts....most likely same problem....mine are still working now. A good tech should trace power to amp section and signal through amp. ...about $15 reasonable repair....no more.

Speakers not Charging


Make sure the power cord is completely plugged into the back of the speakers. make sure the speakers power button/switch/knob is turned on. if both of these things are not the reason call the company you got them from and ask about a warranty.

Without seeing it it is hard to tell, but it could be that the speaker cone is out of the magnet hole, and is missaligned, in other words the voice coil could be sitting on top of the magnet instead of in the magnet hole... If you DELICATELY push on the speaker cone does it move in and out???

Everything is plugged in turned on but no sound. I recently moved my computer system to a new location and have not been able to get the speakers to work help


I assume this is a powered unit, so first off make sure the power cord is plugged into the wall and the speakers. then make sure you are plugged into the correct jack on the PC. It is usually green in color. Finally, make sure the volume on both the speakers and the PC are turned up. Report back wit hresults.

I suspect you have not plugged them back into the correct socket. The plug is coloured green and therefore should go back into the green socket. you have probably plugged it back into the blue or pink sockets. Use a torch to check that is in the green one.

Speakers not working


Check the easy stuff first: make sure the volume is at a reasonable level and play sounds from multiple sources like pandora, youtube, a local mp3 etc to make sure issue is consistent.

Next make sure the one or more wires are plugged into the correct ports. Or at the very least the green wire is plugged into the green plug on the computer (unless they're USB speakers?).

You could always look at the sound settings of Windows and see (if your sound card has multiple plugs) if the plugs and assigned different functions (base speaker versus microphone/headphone etc.). Hope this helps!

I have tried everything I can think of to fix the problem, but finally gave up and called the person who I purchased it from last June. As I had been using a headset, I don't think we ever tested if the speakers worked with this PC. He is coming to look at it tomorrow. I seem to have ruled out everything except the connection ports on the PC. I hope that he can solve the problem tomorrow.
