在电视机维修工作中,时常遇到行管电流过大的故障。引起此类故障的因素很多,即使维修者手头拥有示波器等仪器,也常感棘手。稍有不慎,还易造成人为扩大故障,烧损更多的元件。笔者在维修实践中,摸索总结出用人为停频方式来检修行管电流过大故障的方法,可快捷地找出故障点。 In the TV repair work, often encountered in charge of the tube is too large a fault. There are a number of factors that can cause such failures, which can often be tricky even for maintenance engineers owning instruments such as oscilloscopes. A little careless, but also easy to cause artificial to expand the fault, burn more components. In the maintenance practice, the author summed up the man-made way to stop the overcurrent fault management method, can quickly find the point of failure.
