随着经济水平的提高,彩电已经成为家庭生活中不可缺少的电器之一。但是彩电在使用的过程中,会有各种各样的故障出现,其中彩电扫描电路发生故障的频率较高。所以彩电扫描电路的故障维修是彩电维修中经常出现的。本文通过多年的经验,首先从彩电扫描电路故障的外在表现进行分析,从而判断彩电的故障部位是否是扫描电路,又能进一步确定故障所在的扫描电路的位置,从而应用不同的检修方法。
With the improvement of economy, color TV has become one of the indispensable appliances in the family life. However, the use of color TV in the process, there will be a variety of failures, including color TV scanning circuit failure frequency higher. Therefore, the failure of color TV scanning circuit repair is often seen in the color TV repair. Through years of experience, this paper analyzes the external manifestation of the fault of the color TV scan circuit firstly to judge whether the fault location of the color TV is a scanning circuit or not, and further determines the location of the scanning circuit where the fault occurs so as to apply different maintenance methods.
