When is the green LED supposed to light up on the front of the speakers?
I received a set from my son, plugged the power supply in and connected them to my PC and there is no sound and the LEDs are not on.

Re: Speakers not working
Most computer speaker system will indicate power when switched on. The on switch could be a push button type or rotary built-in to the volume control. There are however models that are automatically powered on once plug to the mains.
In instances such as this that even though plug to the mains, switched on and yet still LEDS does not light up is indicative of a power supply problem. This could be as simple as a fuse blown or worst burnt components.
Pls, first thing you need to check is if the speakers are rated the same as the local/mains voltage where your are. Example, if the speakers were bought from and meant for US, chances are that they are 120VAC; if your are currently based in Europe, then the local mains would be 220~240VAC, simply plugging in and powering would burn a fuse or a transformer or a regulator. The reverse could possibly also hold true since it will be getting about half of what it is designed to receive (unit is 240 but used in 120).
If the above does not apply to your concern or even if it does, the power supply must be checked, diagnosed and possibly would require repair. This would involve familiarity and knowledge of electronic circuitry and components, use of a DVM and a soldering iron. If you are not comfortable going through this route, perhaps your best bet would be to seek the services of an electronics technician.
Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Dose the green LED light up at the front ? . If it does not its a power supply issue. You must have burnt the transformer in the power supply unit. If the light lights up ans there is no sound it could be the Amplifier Chip (IC ) problem. This will involve soldering and desoldering work not to mention procuring the IC.Cos wise the IC just cost about 3$ ans the transformer about 7$.
The green light represents that the unit is receiving power, if the light is off then the unit is not receiving power. Check the power plug. Check the power switch on the speakers. You may need to push in a knob.
Make sure you can see the small LED light on the speakers. If I remember correctly, those speakers are USB powered, and need to be plugged into the USB port for power, and the green audio output port for sound signal. If they are plugged in, and you cannot turn them on, you have broken speakers. If you CAN turn them on, then ensure that the audio cable is plugged into the green audio output jack (sometimes it has a headphone icon by it) and make sure your computer has not muted the audio.
It looks like you have posted this before. Unfortunately, I don't know what you have tried so I may be repeating some of your earlier troubleshooting.
The subwoofer needs its own power supply to function properly. if it isn't getting enough power, the sub will not work at all.
On the back of the unit, you should see a green LED when the power is turned on. Is this light on all of the time of does it fade / flicker? This would indicate the power supply is going bad and you need to replace it.
Try plugging in earphones to see if the problem is the speakers or the output from your computer. Also, your computer output may be low power output for powered speakers and your speakers are not compatable. You may also be plugged in to the wrong output on your computer.

may be you have not installed the audio drivers.... if not then so install it & then try it will work.. if it is installed then check whether the audio cable from speakers to the cpu is correctly connected to audio jack in the cpu..(u must connect to green audio port) check whether the power supply of the speakers is given r not... check whether the power button of the speaker is on ....
if the same problem persists then there may be miscontact inside the speaker (if the speaker is showing green light when it is on means then there is no power supply cable problem else there may be power supply cable problem try changing it ) else may be the capacitor inside the speaker is gone if the problem persists then take the speakers to technician ....
Make sure that you have the correct power supply for the speakers. If you are connecting them to a desktop, look for the light green 1/8 plug on the back of the computer. Again, make sure that you have the power supply that came with the speakers. Do not plug the power supply in until you connect the 1/8 plug from the speaker to the light green plug on the back of the computer.
