Title: Horizontal deflection circuit
Inventor: MURAKAMI YASUO
IPC: H04N3/23
Filed: 1986-12-22
Abstract: PURPOSE:To improve the reliability by using the contact/opening of a contactless switching element so as to change the capacitance of a capacitor for the S-shape correction thereby eliminating the noise generated at the change in the capacitance and eliminating the improper contact. CONSTITUTION:When a horizontal deflection frequency is low, a base current controller 15 detects it to make a control transistor (TR) 14 inactive. Then a power supply 12 is given to a base of a TR 10 via a resistor 13. In such a state, a collector current of the TR 10 flows at all times and a current flows form the emitter of the TR 10 to the collector by a diode 11. As a result, the charge/discharge current of a capacitor 7 for changing the capacitance for S-shape correction is in a form of sawtooth wave. On the other hand, when the horizontal deflection frequency is high, the TR 14 is operated to make the TR 10 inactive. In this case, the capacitance of the capacitor for S-shape correction consists only of the S-shape correction capacitor 6.
