Horizontal Deflection Block - Sony TVP-08 Training Manual

Horizontal Deflection Block

Overview
The Horizontal Jungle uses an oscillator synced by the HS and AFC sig-
nals to produce the H Drive signal. The Horizontal drive signal is used as
input to produce the horizontal output. The Pin amplifier is used to vary
the amount of current supplied to the horizontal yokes so that more cur-
rent is delivered when the beam is sweeping the middle of the tubes.

A sample of the horizontal output signal is used by the HP/H Protect to
produce the HP signal. The HP signal is fed back to the Horizontal Jungle
to phase lock the Horizontal Drive and Horizontal Output. The H Protect
circuit uses the HP signal to detect proper operation of the horizontal
circuits. If a failure occurs, the protect circuit will shut down the set and
inform IC1009 OSD Processor if a failure has occurred.
