ABSTRACT:
A start-up circuit for a deflection system comprises a deflection circuit including a first oscillator which produces a first signal for producing a deflection signal in a deflection winding in response to the first signal. A second oscillator coupled to the first oscillator controls the frequency and phase of the first oscillator when a direct current potential is coupled to said second oscillator. A rectifying circuit coupled to the deflection circuit and the second oscillator provides the direct current potential to the second oscillator when the deflection signal is being produced.
