松下TC-AV29C扫描电路 问:TC-AV29C扫描电路由几部分组成? 答:该彩电扫描电路的小信号振荡部分由TA8653N集成及外围元件组成,同步分离电路由AN5650集成电路组成,场输出电路由AN5521集成电路组成,行输出电路由三极管VQ_(501)、VQ_(502)组成。 问:为何该彩电设置了枕形校正电路? 答:TC-AV29C采用74cm(29in)大屏幕显象管,由于显象管尺寸越大,偏转角越大,则枕形失真越严重,为此行扫描电路设置了水平方向枕形校正电路。
Panasonic TC-AV29C scan circuit Q: TC-AV29C scanning circuit consists of several parts? A: The color TV scanning circuit small signal by the TA8653N part of the integrated and peripheral components, synchronous separation circuit by the AN5650 integrated circuit, the field output circuit from AN5521 integrated circuit, the output circuit by the transistor VQ_ (501), VQ_ (502) composition. Q: Why is the color TV set pincushion correction circuit? A: TC-AV29C using 74cm (29in) large screen tube, the larger the tube size, the larger the deflection angle, the more serious the pincushion distortion, The horizontal scanning circuit is equipped with a pincushion correction circuit.
