Abstract
A television system includes a television receiver (11) and a remote control (18, 72). If an RGB bias level adjusting mode is set by the remote control, the CPU (74) disables the ramp waveform generator (36) but enables a brightness component cutoff circuit (58a) and color component cutoff circuit (58b) that are included in an YC mixing circuit (58). In response, vertical deflection is suspended, and a video signal having a pedestal level is outputted onto a display (70). 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.
