在电视机电路中,测量那些对检修有决定作用的点的电压值;测量那些能反映某一部分电路工作状态的电压值,这就是所谓的关键点电压测量。有经验的维修人员,每测量一点电压,便能基本上判断出该部分线路工作是否正常。测量几点电压后,便基本上能压缩出故障范围和部位,灵活运用关键点电压测量法,可以加快电视机检修速度。一、黑白电视机关键点电压
In TV circuits, the voltage values at those points that have a decisive role in overhauling are measured. Measuring the voltage values that reflect the operating state of a particular part of the circuit is the so-called keypoint voltage measurement. Experienced maintenance personnel, each measure a little voltage, we can basically determine the part of the line work is normal. After measuring a few voltage, it can basically compress the fault range and location, flexible use of the key point voltage measurement method, you can speed up the TV repair speed. First, black and white TV key point voltage
