一、“S 校正”电路进入大屏幕彩电修理时代,S 校正电路是前所少见、故障频多的部分。64 cm(25英寸)以上大屏幕彩电均设有水平光栅校正电路,亦称枕形校正电路.通常简称“S 校正”电路,这与54 cm(21英寸)以下小屏幕彩电有着本质区别。电路结构及基本工作原理:在电路结构上,通常有专用集成电路和纯分立元件两种类型;供电方式,国产
First, the “S correction” circuit into the era of large-screen color TV repair, S correction circuit is a rare before, the failure frequency of the part. Large screen color monitors above 64 cm (25 inches) have horizontal grating correction circuits, also known as pincushion circuits, often referred to as “S-correction” circuits, which are essentially different from small-screen color TVs below 54 cm (21 inches). Circuit structure and basic working principle: In the circuit structure, usually there are two types of dedicated integrated circuits and purely discrete components; power supply, domestic
