Hello
That sound comes out from the power supply regulator board to your tV. Replace it as card basis. There is no repair to this baord. Its SMPS transformer makes the noise.

I purchased the 16 inch Ultimate Buzz Lightyear for my grandson, and it seemed to work fine, but all of a sudden he quit speaking. His lips continue to move, but no voice is coming out. We have changed...


We had the same problem - sound got quieter and quieter until Buzz was mute. My husband gave Buzz a sharp whack on his back where the AAA battery compartment is located and Voila - Buzz is speaking again.

Humming sound


Samsung states - A buzzing sound from your plasma TV is normal. It is caused by the electrical charges used to create the images on the screen. The buzzing, however, should not be so loud that you can hear it when the volume on the TV is set at normal levels.It is also important to determine the type of buzzing sound. A sound like a ground hum is completely normal. This buzzing can originate near the power cord connection or from the SMPS board position on the upper back of the TV. The buzz will be more audible as contrast increases on the screen, most notably when displaying an all white screen. If the buzzing sound is loud, you may have the Contrast set too high. Lower the contrast to reduce or eliminate the buzzing.You may also have loud buzzing if the rear of your Plasma TV is too close to a wall or other hard surface. Try moving your TV away from the wall until the buzzing is minimized. [1]
If the buzzing is at a higher frequency and resembles a crackling sound (like the sound of Velcro being pulled apart), and originates from the upper middle back of the TV, you likely have a failing SMPS board. Place a support call with Samsung to have the SMPS board replaced.FP-T5084 Have a known buzzing problem with a very simple fix.If the buzzing is coming from the left or right sides of the rear and the volume can be changed by pressing lightly on those locations, you are probably hearing the vibration of the grounding springs on the back panel. Call Samsung (or whoever) and have a technician confirm the problem. The easiest fix is to insulate the offending spring by applying some felt tape.

Toshiba 36zp18q buzzing noise.


Humming sounds come from the power supply and buzzing sounds come from other circuitry. Most likely a capacitor somewhere.

Buzzing


The noise is caused by dust on one of the toroidal transformers(usually a round looking thing with wire wound around it). Go to the back of your television and try and pinpoint were the sound is coming from. Turn your television off and blow it out with compressed air if it is close to air vents in the television. If you cant see it you might have to open your television back panel.
