1 -- Color tuner: TU200 TEPU5-02 Selects a desired radio wave and changes it to the video IF signal. 2 -- Video IF amp.: Q200 2SC4238 Amplifies the video IF signal output from tuner TU200 by 10 times (20 dB). 3 -- Video det./Sound det./FM det./AFT/AGC: IC200 M51348FP Eliminates the carrier wave in the video IF signal, and picks up the video signal and the sound IF signal. Also, the sound signal is picked up from the sound IF signal by FM detection. 4 -- Audio amp.: IC600 NJM2070M Sound amplification. 5 -- Chroma circuit: IC300 IR3P90Y Generates the tricolor (red, green, and blue) from the video signal. 6 -- Display control/Auto-tuning control: IC700 MSM6770CGS Controls the display. 7 -- Tuning voltage generator: IC270 BA10358F Generates the tuning voltage with the tuning pulse output from 6.
