The correction capacitor generally refers to a capacitive device that corrects and compensates for a certain signal in the circuit. In the horizontal output circuit, there is a capacitor connected in series with the horizontal deflection coil, which is added to compensate for the extensibility distortion of the picture tube, which is usually called an S correction capacitor. S correction capacitors are used on televisions and monitors to correct image distortion caused by the difference in electronic scanning rates between the center and edge of the picture tube.
Note: When installing the capacitor, be sure to ensure the dryness of the installation environment, otherwise the capacitor may be short-circuited. In addition, when dealing with the failure of this kind of capacitor, we must also pay attention to it. First, we must open the circuit for maintenance, otherwise there may be a short circuit and it is not conducive to the handling of the failure. Secondly, before discharging, you must first connect the ground wire, and then use the electric rod to discharge the capacitor.
