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.

Some desktop computers do not have speakers. You have to plug in speakers. They have their own power supply, and a cord with a lime green plug. It plugs into the lime green hole on the back (or sometimes also on the front) of the computer.
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.
Post the Model #'s of the products involved and I can be a little more specific. Using generic troubleshooting, First: make sure you have the wires for the receiving unit of the wireless speakers hooked up to either "A" Front or "B" Front. thenmake sure your receiver speaker switch for the corresponding location is on. It will light up on the front of the receiver either A, B, or both. Now, turn on the AV receiver and Tune it to a strong radio signal in your area, turn up the volume 1/4 to 1/2 way. Power the wireless units on. Both the speakers and their receiver should have a power button or at least a light to let you know they are getting signal. keep the speakers close and fine tune the wireless receiver with them until the led light on the front of the speakers is solid. You should have good audio at this point.
The other way the wireless receiver is hooked up is with RCA cables to the AV receiver. Without knowing what AV receiver you have, plug the RCA's into an "Output" like "Front Main Pre Out" or "VCR/Tape2 mon" or just plain "Monitor out" Depending on which Output you use will determine the setting on the receiver. If you need further clarification, post your equipment model numbers and I can tell you exactly what to do. Hope this helps
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 ....
1991 Ford Explorer XLT Radio and Speaker Wire Colors
Pulled out the stock radio and found two plugs on the back of it. One plug had 7 wires (Power, Dimmer, Amp etc.) and one had 8 (Speakers).
7 wire plug (I could see these wires immediately from the plug):
Car Radio Battery Constant 12v+ wire = Light Green w/ Yellow Stripe Car Radio Ground Wire = Black Car Radio Accessory Switched 12v+ wire = Yellow w/ Black Stripe Car Radio Dimmer Wire = Light Blue w/ Red Stripe Car Radio Illumination Wire = Orange w/ Black Stripe ?? Don't know ?? Red Wire (No power to wire Constant or Accessory) Car Radio Amp Wire = Blue
8 Wire Plug (Wires were wrapped in a grey outer sleeve, had to cut sleeve to get to wires.):
Right Front: White w/ Green Stripe (+) Brown (no stripe) (-)
Right Rear: Purple w/ White Stripe (+) Light Blue (no stripe) (-)
Left Front: Light Green (no stripe) (+) White w/ Orange Stripe (-)
Left Rear: Light Blue w/ Black Stripe (+) Yellow (no stripe) (-)
Speaker Wires (found at the individual speakers in the doors)
Right Front: White w/ Green Stripe (+) Green w/ Orange Stripe (-)
Right Rear: Orange w/ Red Stripe (+) Black w/ White Stripe (-)
Left Front: Orange w/ Green Stripe (+) Blue w/ White Stripe (-)
Left Rear: Red w/ Green Stripe (+) Red w/ Blue Stripe (-)
Hope this helps. I spent hours looking for the correct color key and this one works for my '91 Explorer.
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.
Based on your post/description, the Durabrand 2.0 CH USB Speaker System is a basic external speaker that plugs into your PC's speaker/headset output (green jack). It is supposed to get its power from the +5VDC supplied by the USB port. Some USB port have current limiting therefore it can be anywhere from 10 - 500 mA. The power requirement of your external Durabrand speaker maybe beyond what the PC's USB ports can supply. It does not need to be recognized by the OS since it only connects to the USB to get power but there is no data interaction.
Perhaps what you can do is get an external +5VDC power supply whose output is in USB type connector. The current rating would depend on the requirement of your speaker. Offhand, if the speakers are not that big, probably a 1 Amp would do.
This is of course assuming that the Durabrand speaker system is fully functional. If with an external power supply it is still a no go and you have verified that sound do come out of your green jack (with the use of an ordinary headset), then the Durabrand is defective.
Hope this be of help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
