场输出电路故障是彩电常见故障之一,表现为屏幕只有一条1～2mm水平亮线,但伴音一般正常。由于场输出电路比较简单,所以检修技术要求并不高,只要有一些电子技术基础就可自己动手修理,并由此入门逐渐提高个人的家电维修水平。作者现将近几年业余检修彩电场输出电路故障的经验介绍如下,以供其他同志维修彩电时参考。 一、场输出集成块工作原理及其引脚电压 Field output circuit failure is one of the common faults of color TV, the performance of the screen is only a 1 ~ 2mm level bright line, but the sound is generally normal. As the field output circuit is relatively simple, so overhauling the technical requirements are not high, as long as there are some basic electronic technology can repair yourself, and thus gradually improve the level of personal home appliance repair. The author now in recent years, amateur overhaul repair color TV field output circuit fault experience is as follows, for other comrades to repair color TV reference. First, the field output integrated block operating principle and pin voltage
