摘要
The present invention relates to a TV afterglow prevention circuit, and in particular, in order to supply power which is delayed more than the power-off point when the TV is turned off, a spot prevention voltage is generated and applied to the deflection circuit part when the power is turned off, thereby charging the inside of the CRT. The present invention relates to an afterglow prevention circuit when the power supply is turned off by gradually releasing the generated energy onto the screen to prevent the afterglow phenomenon.
