彩电场扫描电路故障率比较高,出现故障后必然需要通过电路分析来查找故障根源,如果维修者对“场块”内部框图及其主要特点也有较为透彻的了解,那么在分析问题时,可再根据“场块”内部与外部电路关系进行“内外”综合分析,可使思路更加开阔、更加明确,这对于快速排除故障来说,是非常有利的。 1.AN5534为12个脚单列直插、自带小散热片塑封结构,其外形及引脚功能如图1所示。主要特点如下:
The failure rate of the color electric field scanning circuit is relatively high. After the fault occurs, it is necessary to find the root cause of the fault through the circuit analysis. If the maintainer has a thorough understanding of the internal block diagram of the “field block” and its main features, then when analyzing the problem, According to “field block ” internal and external circuit relationship “internal and external ” comprehensive analysis, can make the idea more open, more clear, which is very beneficial for quick troubleshooting. 1.AN5534 12-pin single inline, comes with a small heat-sink plastic structure, the shape and pin function shown in Figure 1. The main features are as follows:
