摘要: An apparatus for automatically stabilizing the black level of a displayed picture when (1) an automatic function is OFF, (2) error occurs between at ON state and OFF (3) variation disturbance during activation deactivation stabilizer. Black variations stabilizer are controlled by processing cathode current in negative feedback loop controlling CRT grid voltage, storing divided voltage converging period another order to adjust value.
