CONT.
Voltage goes up if a
sync signal is entered
and horizontal AFC is
locked; otherwise, the
voltage goes down.
therefore, the pin can be
also used as a MUTE
detector. At that time,
pay attention to high
impedance.
Pulse as shown below is
putput.
Power supply for VC,
AFT, RF AGC and SIF
DET.
Horizontal pulse of 24 µ
s wide is output. It is
open emitter output.
Color control pin. Its
voltage goes to. 0V
when service SW is ON.
