当集成电路电视机出现水平一条亮线或场不同步时,有可能是外围电路故障,也可能是集成电路内部故障。KC581C 内电路如图1所示。它的外围元件数据是固定的,全国同类电视机中,各引出脚电位基本一
When the integrated circuit television level of a bright line or field is not synchronized, it may be a peripheral circuit fault may also be an integrated circuit fault. KC581C circuit shown in Figure 1. Its peripheral component data is fixed, the national similar television sets, the lead pin potential of a basic
