PURPOSE:To attain more accurate deflection distortion correction with respect to the pin cushion correction circuit having a corner distortion correction circuit separately for lower and upper parts of a CRT. CONSTITUTION:The television receiver is provided with an amplitude adjustment circuit 6 adjusting an amplitude of a correction signal to correct corner distortion at a lower part of a screen, an amplitude adjustment circuit 8 adjusting an amplitude of a correction signal to correct corner distortion at an upper part of the screen, and a multiplier circuit 13 generating a parabolic wave signal to correct horizontal pin cushion distortion on the screen, and better deflection distortion correction is attained and factory adjustment is simplified by the provision of the circuits interlocking the amplitudes to interlock corner distortion correction and pin cushion correction. |
