笔者曾经遇到过两例比较奇特的“软”故障,均是用尽了九牛二虎之力一无所获后,用电热风一吹便把故障彻底排除了。比较两例的故障特征,有一个明显的共同点,就是“怕冷”。说到这您不要以为“怕冷”病都可以用加热的方法去解决.实际不然,很多“怕冷”病是由于元件老化变质、性能不稳定造成的。用加热的方法只能起到帮助判断故障的作用,即使当时见效,也不能根除故障。下面就简述两例软故障的分析与检修过程,供大家参考借鉴。例1:奥林匹亚51cm(20英寸)彩电,每次开机场
I have encountered two more strange “soft” faults, all of which have exhausted all in one fell swoop the powerless, the electric wind blows the fault completely ruled out. Comparing the two fault characteristics, there is a clear common ground, that is, “fear of cold.” Speaking of which you do not think “afraid of cold” disease can be used to solve the heating method.In fact, many “cold” disease is due to aging components, performance instability caused. The method of heating can only help to determine the role of failure, even if effective at the time, it can not eradicate the fault. The following is a brief description of two cases of soft fault analysis and repair process, for your reference. Example 1: Olympia 51cm (20 inch) color TV, each opening airport
