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.

On the front of the laptop there is a circular knob, play a music cd and then turn the knob from left to right and see if the sound comes back, if that doesn't work then make sure where the speaker is in the bottom right hand side of the screen click on it and make sure the volume is turned up.
If it still doesn't work then reload the sound drivers. At this point if the sound still won't work then that means that either the speakers or the motherboard is bad and you won't know for sure unless you replace the speakers first.
Check the Vibration damper rods to be sure that... 1. They are there and mount is solid. 2. If they are broken in 1/2. 3. The plastic knuckle mounts are not missing/broken. 4. There is oil in the shock absorber/spring section of the rods.
Also - there are suspension springs on the bottom of the tub that could be broken and/or missing.
Replace/repair as necessary.

You need to remove the front tv panel, search for the screws right behind the screen and speaker area on the sides of tv. Should be four of them, carefully remove the lower have/quarter and you will find a control box, 6 knobs. Try adjusting them to clear the problem, each color has its own knob, be sure to mark their original position befor adjusting. When you find the red adjustment knob, you should be able to turn it down enough so that it doesnt overpower the rest of the colors. Good luck.
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.
