彩色显像管磁偏转电路有些特殊,检修时有一定的难度,这是因为它不仅要使组件本身无故障,而且对组件的装组件与彩管的配合定位等都有比较严格的要求,否则将造成光栅失真和影响彩管的会聚和色纯,使图像质量严重下降。为此,本文将就彩色显像管磁偏转线圈组件的结构和拆卸、安装、定位标记方法,以及注意事项作一些基本介绍,同时还把笔者所使用的一种独特的“轴向准线定位法”,也介绍给大家。
Color CRT magnetic deflection circuit is somewhat special, overhauling a certain degree of difficulty, because it not only to make the component itself is not fault-free, but also for components of the components and CPT with the positioning and so have more stringent requirements, otherwise it will result Grating distortion and affect the convergence of CPT and color purity, serious deterioration of image quality. To this end, this article will color CRT magnetic deflection coil components of the structure and removal, installation, positioning mark method, and precautions for some basic introduction, but also the author used a unique “axial alignment method” , Also introduced to everyone.
