Abstract

PURPOSE:To prevent screen change accompanied with audio change, by superimposing a current which changes in synchronizing with the audio signal level change on a vertical winding of a longitudinal pin cushion compensation transformer. CONSTITUTION:In a longitudinal pin cushion compensating line of a block C, a transistor circuit Q4 11 , R2-R6, C7 are added as a variable impedance element in parallel with a bias resistor R1, and the bias current of a longitudinal line pin cushion correcting transformer T1 is changed in synchronizing with the load change of an audio output circuit E. The bias current of said T1 is the sum of collector current of a transistor Q4, and a current flowing to the resistor R2.
