SYNCHRONIZATION
The IC701 performs the horizontal synchronization (oscillator).
A horizontal rate output pulse is coupled from IC701 pin 12 to
the horizontal driver Q702. The driver stage drives the horizon-
tal output Q703.
The horizontal sync signal coupling IC701 pin 1 is derived from
dividing between R708 and R709.

The AFC circuit consists of phase detection circuit of IC701 and

to prevent the pulse from

Under normal operating conditions, the resultant voltage main-
tains the specified value.
If a malfunction cause excessive high voltage, the amplitude of
the pulse from the FBT increases, causing a corresponding in-
crease in D704 which results in a voltage increase at pin 13 of
IC601. A voltage increase at IC701 pin 13 makes the X-ray pro-
tection circuit conduct, and the horizontal oscillation operation
no longer functional.
The circuit latches as above, and itis necessary for the circuit to
turn the power off for at least 30 seconds to function again.
