PROTECT
Power supply pin for
horizontal and vertical
systems. it's current is
about 34mA.
Increasing R provides a
faster AFC response to
minimize picture skew-
ing in the VCR mode.
However this will
increase horizontal jitter
in weak signal areas
Flyback pulse is limited
to 4V, to generate the
AFC 2 detector pulse.
Peaks around 4V caus-
es jitter;also the picture
is displaced to the right
due to the integration of
the flyback pulse.
CSB500F18 is used.
Applying voltage of 0.7V
or more operates the X-
ray protector. connect to
GND if not using the pin.
