在显示器的维修中,有“常规观察法”和“电路故障观察法”两种,恰当运用,能起到事半功倍的效果。一、常规观察法维修人员打开故障机的后盖,用人体感应直接观察机内元件有无缺损、断线、脱焊、变色、变形及烧坏情况;再观察机内有无打火、行频叫声。对于无光栅的,应重点检测保险管是否烧断、显像管是否漏气、破裂以及灯丝是否点亮等情况。从而发现一些显而易见的故障点。用人体感官可直接检查出来的明显故障有6种:
In the monitor maintenance, there are two kinds of “conventional observation method” and “circuit failure observation method”, proper use, can play a multiplier effect. First, the conventional observation method Maintenance personnel to open the back cover of the malfunctioning machine, with the human body induction direct observation of the internal components with or without defects, disconnection, desoldering, discoloration, deformation and burnout; then observe the machine with or without sparks, OK Frequent cry. For non-grating, should focus on testing the fuse is blown, tube leaks, rupture and the filament is lit and so on. To find some obvious points of failure. With the human body senses can be directly checked out 6 obvious faults:
