A television centering circuit includes a non-linear conduction network (48) coupled in series with an inductance (L1). The series arrangement is conductively coupled in parallel with a horizontal deflection winding (LY). A control circuit (49) for the non-linear conduction network utilizes negative feedback (from R1) to sense and control the current (iL1) in the inductance (L1) when the current is of a first polarity, thereby regulating the average value of the current (iL1) in the inductance (L1) and in the deflection winding (LY) to provide raster centering. |
