在彩显所发生的各种故障中,因缺少三基色中的某一种色彩,而引起的色彩失真故障,出现的几率还是比较高的,尤其是那些使用时间较长,规格型号较早的显示器更是如此。缺色、色彩失真故障检查起来难度并不大,但是,处理起来可就不那么简单了。需要对彩色信号放大、削波、延迟、矩阵等电路的工作原理,有比较透彻的了解。同时,一些需要调整的部件,比如色纯度调整,必须借助一些专用的测试仪器,例如“全彩色信 In the color of the various failures occurred due to the lack of one of the three primary colors in color, color distortion caused by failure, the probability is still relatively high, especially those who use a longer time, the older models The display is even more so. Lack of color, color distortion troubleshooting is not difficult, but can be handled is not so simple. The need for amplification of color signals, clipping, delay, matrix and other circuits work principle, a more thorough understanding. At the same time, some components need to be adjusted, such as color purity adjustment, must use some special test equipment, such as ”full color letter
