The power supply on a television transforms the alternating current electricity from your wall outlet into direct current that the components of the TV can use. The power is transformed for voltage, rectified to change from AC to DC, smoothed out and regulated through the use of capacitors so that the internal circuitry of the TV gets a constant flow of DC voltage. The connection between the components of a power supply is made by relay switches that are set to open or close by an electronic signal. When a relay switch is activated, it makes a clicking sound.
