一提起彩电“慢显像”(延时显像)故障,则人们往往把故障原因归咎于:显像管管座漏电或聚焦极生锈短路所致。检修起来也并不困难,只不过是代换显像管管座时有时也遇到一些“麻烦”而已,总之,“小菜一碟”!在此,笔者提出另一类型的两种“慢显像”(延时显像)故障,请加以区别之!例1 机型:北京2103型(三洋 A3机心)LA7680单片机 A mention of color TV “slow imaging ” (delayed imaging) failure, then people often blame the cause of the malfunction: CRT socket leakage or focus pole rust short circuit. It is not difficult to repair them, but only replace the tube seat sometimes encountered some “trouble” only, in short, “a piece of cake”! Here, I propose another type of two “Slow imaging” (delayed imaging) failure, please distinguish them! Example 1 models: Beijing 2103 (Sanyo A3 movement) LA7680 microcontroller
