How do I repair

I guess you have tried switching the speaks left to right to check its the speaker rather than the output to the speaker?

If you have it might be worth (If you are able to) opening up the speaker unit to check the wires are still attached and solid, maybe need a little re-solder is needed as the wires are usually very thin.

Cant figure out how to hook them up

Two audio input cables are supplied with the speakers. If your computer has a stereo mini jack, use the cable with a stereo mini plug. Otherwise, use the cable with RCA plugs on both ends. Match the colors on the connectors to the colors on the jacks, red to red and white to white.
The speaker cable is already attached at one end to the accessory speaker. Plug the other end into the TO ACCESSORY SPEAKER jack on the powered speaker.
1. Connect one end of the audio input cable to AUDIO INPUTS A. 2. Connect the other end to your computer's AUDIO OUTPUT jack. We recommend using LINE OUT if your computer sound card offers more than one option. 3. To connect a separate CD-ROM, or another source, repeat steps 1 and 2 using AUDIO INPUTS B.
You must connect the AC power pack to operate the speakers. 1. Plug its cable end into the power jack on the powered speaker. 2. Plug the power pack blades into the wall outlet. 3. Turn on your computer sound source or external sound source.

My lap sound problem..

Some things you need to check

1. Cable connection of the speaker to your computer and the power cable if its plug in correctly. Normally the Audio cable of the speaker is plugged into the green audio port on the computer.

2. You speaker is on mute. Check the speaker icon located on the lower left side of you desktop. If its on mute then try to un-mute the volume and test the speaker.

3. The driver is not installed properly. Check the device manager if there is a Question/Exclamation mark on the Audio devices.

4 If everything are Ok. try to plug the Audio cable of the speaker to any of your Portable sound devices like Ipod. If that still does not work then you need to replace the soundbar. Contact Dell for a free replacement if still under warranty.

Thank you.. Hope this helps..

There is no sound. I have connected it to my new Toshiba laptop

Hello there,

When you plugged it into your laptop, turned it on and increase the volume, do you hear only a humming sound from the speakers? Try to plug the speaker to an mp3 player as well to test if it still doesnt give out any sound. If it still doesnt, then your speaker must have a wiring connection problem inside that needs resoldering. Here I supposed that your laptop's internal speakers is working and is able to work with other audio devices like a headset or an earphone.

Two speakers hum noise

Very doubtful that hum issue is ground potential difference from multiple power outlets as power cord is not grounding type (it is transformer isolated). I do agree that it is good practice to connect all audio equipment to common power strip though, especially with pro sound. Check the audio cords connecting your speakers to the coumputer sound card: 1) Make sure they are connected to the correct jacks and plugged in all the way, 2) wipe the connectors off with a clean paper towel wetted with a smidge of WD-40, 3) replace cords if all else fails. I have also seen solder joints fail on the power supply capacitors (due to vibration) causing hum -- but leave this repair to an electronics technician due to dangerous voltages.

Getting buzzing sound from speaker but can here sound from them.

You could have an earth loop which causes a hum/buzzing sound.
Is your computer and powered speakers plugged into different mains?
Connecting amplifiers and speakers to different power sockets will create earth loop problems
This can be fixed by using a single power board connected to a single mains power socket, then connecting all the computer components and powered speakers into this one power board.

Humminf sound from subwoofer

Most humming sounds in speakers is due to electrical currents or wifi signals nearby the speakers.

Do you have any electrical cables near the speakers? Do you have any wifi device near the speakers?

If so move them out/away and see if there is any difference.

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 )
may be the capacitor inside the speaker is gone
if the problem persists then
take the speakers to technician ....
