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 the tuner TU 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 M52042FP
Generates the tricolor (red, green, and blue) from the video signal.
6
-- Osc./A-D Converter/Display Control/ Auto-Tuning Control : IC700 MSM6625-02 GSK-640F
Converts the color signal into a digital signal.
Also, generates the clock pulse for the display and controls the display.
7
-- Tuning Voltage Generator: IC500 MSC1169MS-K
Generates the tuning voltage with the tuning pulse (TU) output from 6.
8
-- Display Voltage Generator: Q800 ~ Q803 Q805 Q806 2SD1149-S,
2SD601A-R
×4, 2SB709A-R
Generates the display voltages V0 ~ V4 with VEE1 and VCC7 outputs from the power supply.
