I've tried to change the equalizer, and the only way to get rid of it is to turn the balance to one side or the other. I also have made adjustments to the 300 and 100 Hz levels, and it would take it out a little, but not all together.
What can I do to fix this?

That TV has a lot of audio adjustments on it. Try changing the equalizer settings in the mid range. You may also want to see what it does when you hook something else to it and check the sound. If all else fails you can try the digital audio connection to see if that is clear. Otherwise you may to replace the audio board.
I think of a balanced scale in my mind when I start these questions. What ever I do to one side, I have to do to the other side to keep it balanced. It starts balanced and I have to keep it balanced.
(-1) (-1)(7-4x) = 9 (-1) multiply both sides by -1 to get rid of the negative sign
7-4x-7=-9-7 subtract 7 from both sides
-4x = -16
-4x = -16
----- ----- divide both sides by -4 to get x by itself
Check by putting our answer in the original equation and see if the left side is equal to the right side.
If you feel that humming noise then it's definitely a worn out wheel bearing. It is connected on the wheel hub. You will need to remove the CV (constant velocity) joint to gain access to the wheel bearing. Have it replaced to get rid of the humming noise.
Hope this helps and thank you for using FixYa! Have a good one!
try unplugging any equipment that you have attached to the tv one at a time, such as dvd players, surround sound, cable box, etc. also if you have a cable box attached, try adjusting the volume on it. if you have everything unplugged from tv and it still hums, then it may be a tv issue
Depending on the pitch. humming noises are either a motor ie: fan motor or if it is very low a defective capacitor . Since you have the yellow band and the high pitched beep my fist thought is somthing defective in the power supply. Take it to an authorized servicer.

I can't confirm if this works at this moment since I don't have access to my TV.
I think I had the same problem. This is how I fixed it.
I have my vizio 42 hooked up to a Harmon Kardon surround sound, and the digital cable box. Essentially, I can adjust the volume 3 ways - through the tv, cable box or av receiver. The humming sound happens when you have the volume maxed out on the av receiver and not the cable box.
For example, the sound level on my Harmon Kardon goes from -10 (lowest) to 10 (loudest), with 0 being the middle ground. The buzzing was happening when the Harmon Kardon was set to 10, and I was using the cable box volume to adjust the sound. To fix it, I turned down the volume on my receiver to 0, which may be about 50% max volume of the receiver. Then, I switched devices and used the volume on my cable box. This got rid of the static I was getting. Hope that helps.
