(1) BUS control data preset.
(2) Horizontal oscillation frequency is 15.75 kHz (00).
(3) SW6 open. Measure the Voltage of pin 6 V6 (no external supply).
(4) Connect external supply with pin 6, and supply the voltage (V6).
(5) Input signal (below figure) to pin 21 (SYNC1-IN). When INPUT SW is SYNC1-IN , measure V1 and V2 of pin
(6) Supply V6 − 0.1 V and V6 + 0.1 V to pin 6, then measure V3 and V4.
(7) Calculate by following equations.
(1) Increasing the voltage of pin 8 V
