所谓彩电“软”故障即出现时无规律可循,间隔时间不等,短则几分钟,多达几小时。甚至维修者对被怀疑的元件用替代法、冷却法及加热法很难排除。笔者近日制作一台彩电“软”故障检测仪。仪器用八块量程可调的小型电压表,分上、下两排固定在硬质塑料板上,通过0.1A的保险器、用线接至到测试回路端子(再用软线将被测彩电的测试点与端子连接),则可用较短的时间检测出“软”故 The so-called color TV “soft” failure that appears when there is no law to follow, ranging from a short time, a few minutes, up to a few hours. Even maintenance personnel find it difficult to exclude suspected components from substitution, cooling and heating. Recently, I made a TV “soft” fault detector. Instrument with eight adjustable range of small voltmeter, points, the next two rows fixed to the rigid plastic board, through the 0.1A fuse, with a wire connected to the test circuit terminal (then the cord will be tested color TV Of the test points and terminals connected), you can use a shorter time to detect “soft” so
