Abstract

Perfeccionamientos en circuitos de protección de receptores de televisión que comprenden: una bobina de deflexión; un circuito de deflexión acoplado a la bobina de deflexión para producir corriente de explotación en la bobina de deflexión durante un ciclo de deflexión, comprendiendo el circuito de deflexión un primer y un segundo terminales en los cuales se desarrollan un primer y un segundo terminales en los cuales se desarrollan un primer y un segundo voltajes de ritmo de deflexión, caracterizados porque el primer voltaje de ritmo de deflexión comprende en condiciones de avería un voltaje de componente de avería presente durante una parte por lo menos del ciclo de deflexión, estando prácticamente ausente el voltaje del componente de avería del segundo voltaje de ritmo de deflexión durante dicha parte, medios de combinación acoplados al primer y secundo terminales para combinar el primer y segundo voltajes de ritmo de deflexión y producir una señal de avería en un tercer terminal en condiciones de avería; y un circuito de seguridad que responde al voltaje desarrollado en el tercer terminal para proporcionar una señal de desactivación con el fin de desactivar el funcionamiento normal del receptor de televisión cuando está presente las señal de avería.
