  • Page 64 9. ABL circuit The ABL circuit consists of Q2006 for PIC ABL and Q2005 for BRT ABL. Respective emitters receive the ABL voltage from deflection block and bases receive the DC voltages that are generated by voltage- dividing. Respective collectors are connected to pin-46 (PIC control) and pin-7 (BRT control of IC2001. When these transistors turn on, the respective control voltages decrease so that the ABL operation is implemented.

    5-2. BI Board 1. Y/C Separator Circuit 1-1. NTSC/PAL mode The composite input signal that is input through the Q board is band-width limited by FL801, amplified by Q803/Q804, passed through the digital comb filter (IC801 pin-25) so that it is separated to the Y signal and the chroma signal.
  • Page 66: C Board

    6. PAL Low-pass Filter The R-Y signal that is output from IC2804 pin-23 passes through the active low-pass filter (Q3809, Q3810) and is input to IC3802 pin-16. IC3802 contains the built-in 1H delay circuit using a line memory. The output signal after 1H delay is added to the non-delayed signal at pin-11 and is output. The R-Y signal from pin-11 is output via the switch circuit (IC3804, IC3806) and the level adjustment circuit (IC3807).

    5-4. Deflection Circuit and High Tension Circuit The following circuits consisting the deflection circuit and high-tension circuit, are contained the three circuit boards of G board, D1 board and D board. Parts and components in the G board have the parts reference number of 500 series. Parts and compo- nents in the D1 board have the parts reference number of 1500 series.
  • Page 68 Switching of the S-shape compensation capacitors is done by Q2512, Q2513, Q2514, Q2515, Q2509 and Q2510. Switching of the S-shape compensation capacitors is done at the three points of the horizontal frequency 15 kHz, 27 to 33.75 kHz and 37 to 45 kHz. Switching of the horizontal linearity coils is done by RY2501 when the 15 kHz signal is input.
