本文阐述了《大屏幕彩电行扫描电路故障分析》行扫描电路的故障发生率中占有很大的份额,在本次论文中,首先介绍了行扫描电路的基础知识,电路的特点和工作。其次,介绍了不同机型的行扫描电路的故障现象,以及不同故障现象的分析方法。对每种故障提出了具体的解决方案和实施方法。 This article describes the “large screen color TV line scan circuit failure analysis” line scanning circuit failure accounted for a large share of the failure, in this paper, first introduced the basic knowledge of the line scan circuit, the circuit features and work. Secondly, the failure phenomenon of line scan circuit of different models and the analysis methods of different fault phenomena are introduced. For each fault proposed a specific solution and implementation methods.
