一、实验名称
利用假负载维修法维修彩电行电路故障。
二、实验环境
行短路故障电视机一台，隔离变压器一台，100W假负载灯泡一个，绝缘导线一根。
三、相关知识
行负载短路，往往导致电视机无光、无声，个别机型还会电源不起振。判断是否行电路短路最简便的方法是测量+B电压是否偏低或为0V，要检测具体故障常用假负载法。
四、实验目的
通过实验掌握行电路故障的特征和检修方法。
五、实验内容及步骤

1〕将隔离变压器串接在220V市电与故障电视机电源之间。
2〕拆下行管。
3〕在行管C极与E极间连接导线，并与100W灯泡相连接，此时100W灯泡成为行负载。
4〕开启电视机电源开关，观察灯泡亮度并测量100W灯泡两端的直流电压。记录下电压值。
5〕按动电视机遥控器的开机键或电视机面板上的频道加减键使电视机启动，观察灯泡亮度并测量灯泡两端直流电压〔无二次开机功
