Your Motherboard has been dismantled inside your TV, most likely from being bumped, shaken, carried, or maybe just from being old and dirty. There is no possible way to fix it without the help of mechanics. If the picture does not work also, then your TV is busted. To get the speakers' motherboard repaired, I suggest you go to a proffesional Technology Shop (such as The Source) and get it repaired for around $50 - $85.

1) Turn your speakers off. 2) While blowing a can of compressed air into the switch, twist the knob up and down a bunch of times. 3) Repeat step 2 for roughly 10 minutes, blowing the dust out of the volume controller.
If you have an extra headset around, plug it into the same place the speakers are plugged into, if it works, your speakers are bad (or check to make sure the power light is on on them and that their volume knob is turned up).
If you still do not get sound, click on your little volume/speaker icon by your clock, then click 'mixer' at the bottom of it (Windows 7 hopefully?). Make sure the different volume controls are turned up because sometimes one low one will affect the entire system.
(If Windows XP, right-click the speaker, then 'Open Volume Control'. Adjust until you hear sound.)
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.
This issue could be caused by any of
the below reasons.
Sound card does not work
Speakers are not connected properly
No power to the speakers
Volume on speakers turned down
Volume on sound card turned down
make sure the speaker setup is correct. It is
possible that during an installation of another program that the speakers
software setup was changed causing issues with your sound. To do this
follow the below steps.
Open "Sounds and Multimedia Properties" or
"Sounds and Audio Devices" in
Click the "Audio" tab
In the Audio tab click the "Advanced" button
under "Sound Playback."
In the Advanced Audio Properties window make sure your
speaker setup is correct. If you're not sure what to set this
setting as, set it to the default "Desktop Stereo
If you changed this setting click "Apply"
and close out of all windows.
Ensure that the sound card works
properly by connecting either another pair of speakers to the
computer, or a pair of headphones.
the left speaker will generally have a cable
cannot be removed from it. This cable should be connected to the
other speaker (generally this cable has no color or is white / gray).
The next cable is the line out cable, it is generally green in color
and should go from the right speaker to the line out hole in the
back of your sound card.
Finally, the power cable generally should be connected to the
back of the right speaker, or in some cases, the sub woofer. The power
cable can vary; while most speakers are in the above configuration,
some speakers may also not utilize a power cable connection but
instead have batteries, while other speakers that connect to the
side of your monitor may use a portion of the power from the monitor
itself (via another type of cable).
Most speakers will have a small
(light) indicating if the speaker is on. Verify that if this light
is present that it is illuminated.
If no LED is seen or the speakers don't appear to be
getting power, verify the power cable is properly connected to a
working outlet or if your speakers use batteries that the batteries
are good. Finally, most speakers can be turned on either by using a
button or by moving the volume knob from left to right.
Verify that the volume knob on the
speakers is properly turned up. If you are un-certain what
direction to turn the knob, play a long sound file or CD and while
the sound is being played, adjust the knob left to right or up to
The sound is also able to be turned up and down
through the software installed on the computer. Verify the sound
settings in the software are properly turned up.
Finally, if all of the above recommendations do not resolve your issue
and connecting another pair of speakers or headphones to the computer
does work, it is likely that the speakers are bad. It is recommended that you
contact the manufacturer of the speakers or
computer for a new replacement.
Hi, it is possible that the sub volume control is worn out. If your particular brand/model uses the rotary/wiper type (variable resistor) then replacing it should do the trick but this involves soldering which be done by an electronics technician or qualified to perform such repairs/replacement. Hope this helps. Cheers.
volume control knob is damaged inside ,try to put 3drops of
kerosine mixed with edible oil in equal amount.care should be taken not to get it on the electronic board and adjust the knob continuously ,if this doent work u must replce the volume controll
