Abstract
A television system includes a television receiver ( ) and a remote control ( ). If an RGB bias level adjusting mode is set by the remote control, the CPU ( ) disables the ramp waveform generator ( ) but enables a brightness component cutoff circuit ( ) and color component cutoff circuit ( ) that are included in an YC mixing circuit ( ). In response, vertical deflection is suspended, and a video signal having a pedestal level is outputted onto a display ( ). Accordingly, luminescence occurs on the display at a vertically center thereof. Meanwhile, the bias level is adjusted optimal by user's operation of a numeral key provided on the remote control while observing on the display.
