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
EliminatesthecarrierwaveinthevideoIFsignal,andpicksupthevideosignalandthesoundIFsignal.
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 MSM6770GS
Controls the display.
7— Tuning voltage generator: IC270 BA10358F
Generates the tuning voltage with the tuning pulse output from 6.
