摘　　要：本人在《彩电技能训练》的实践教学中发现彩电的场扫描电路出故障率较高,而巧妙使用示波器去检修场扫描电路能快速排除故障。本文以黄河H C3710型彩电机为例,通过对该机型场扫描电路原理进行详细分析及常见故障检修过程,介绍如何巧妙使用示波器检修彩电场扫描电路常见故障的方法。In the practice teaching of ＂TV skills training＂,I found TV field scanning circuit failure rate is higher,and use the oscilloscope to repair the field scanning circuit can quickly eliminate the fault. This paper to type color motor of the Yellow River HC3710 as an example,through detailed analysis and troubleshooting process of the models in the field scanning circuit principle,how clever use the oscilloscope to repair TV field scanning circuit fault method is introduced in this paper.
