Description Horizontal AFC2 filter pin: * Pulse phase of FBP and IC inside are compared and capacitor connected to pin 52 is charged or discharged. * Screen center position adjustment is executed by charge or discharge of DC current with DAC. * According to the time from H-out to FBP-in, V52 is changed, and slice level of inside saw-tooth waveform is changed. Horizontal AFC1 filter pin: * Pulse phase of horizontal sync. signal and IC inside are compared and capacitor connected to pin 53 is charged or discharged. * R1, R2, C1 and C2 are lag-lead filters for AFC1
