该机的电源电路与行扫描电路的工作是相互制约的。因此,把这两部分电路的故障分析放在一起进行。这两部分电路的故障率比较高,要想较快的找到故障点,必须对电路的工作原理有一个基本的了解。同时由于该机的直流供电电路也比较复杂,所以首先弄清直流供电电路,这对电源电路和行扫描电路故障分析及对其它部分电路故障分析都是有益的和必要
The machine’s power circuit and the line scan circuit work is to restrict each other. Therefore, the two parts of the circuit failure analysis together. The failure rate of the two parts of the circuit is relatively high, in order to quickly find the point of failure, you must have a basic understanding of the working principle of the circuit. At the same time as the aircraft DC power supply circuit is also more complex, so first of all to find out the DC power supply circuit, which power circuit and the line scan circuit failure analysis and other partial circuit fault analysis are useful and necessary
