1 — Color Tuner: TU200 TEPE5-01(TV-1800C/I/N) TU200 TEPB5-05(TV-1800D)Selects a desired radio wave and changes it to the video IF signal.
2 — Video IF Amp.: Q200 2SC4238Amplifies the video IF signal output from the tuner TU by 10 times (20 dB).
3 — Video Det./Sound Det./FM Det./AFT/AGC: IC200 M51348FPEliminates 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 NJM2070MSound amplification.
5 — Chroma Circuit: IC300 M52045FPGenerates the tricolor (red, green, and blue) from the video signal.
6 — OSC/A-D Converter/Display Control/ Auto-Tuning Control : IC700 MSM662501 GSK-640EConverts 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-KGenerates the tuning voltage with the tuning pulse (TU) output from 6.
8 — Display Voltage Generator: IC800 BA10358F, Q800 ~ Q806 Q810 Q811 2SD1149S,2SD601A-R×3, 2SB709A-RGenerates the display voltages V0 ~ V4 with VEE1 and VCC7 outputs from the power supply.
