Abstract

PURPOSE:To prevent generation of color slippage dependent upon fluctuation of a high voltage, by improving the following property of the PLL circuit for frequency fluctuation of the index signal accompanied with fluctuation of the high voltage. CONSTITUTION:Adding circuit 21 outputs a voltage corresponding to respective output voltages of high voltage circuit 17, horizntal deflecting 16, and voltage supply terminal 18, and this voltage is added to the output of LPF8 of PLL circuit 4 through DC amplifier 32. This added signal is supplied to voltage control oscillator 6. Now, when the high voltage is fluctuated from a reference value, fluctuation error DELTAv(t) is generated in the deflecting speed of the electron beam. At this time, the index signal frequency supplied to phase comparator 5 of circuit 4 is fluctuated according to error DELTAv(t). Consequently, it is necessary to add control voltage Vc corresponding to this error to the output side of LPF8. In this case, a control voltage equivalent to voltage Vc can be supplied to oscillator 6 by adjusting the level of the added signal to the level of voltage Vc by amplifier 32 and so on, so that a good color picture can be reproduced.
