电视机常因中压滤波电容损坏而引起故障,又因其损坏的程度不同故障现象也各种各样,这便使一些维修人员在处理这类故障时感到困难。笔者在大量的维修实践中常遇到这类故障,现选出三个比较典型的例子,介绍故障特征和检修过程并找出这类故障的共同特征加以分析,供同行们参考。例一故障现象:一台日立CTP—237D彩电,有图声,但图像从左向右有明显的拉丝现象,特别是画面
TV often caused by the breakdown of medium voltage filter capacitor failure, but also because of the extent of the damage is different, there are various fault phenomena, which makes some maintenance personnel in dealing with such failures difficult. The author often encounter such failures in a large number of maintenance practice. Now, three typical examples are selected to introduce the fault characteristics and maintenance process and to find out the common characteristics of such faults to be analyzed for their reference. Example of a fault phenomenon: a Hitachi CTP-237D color TV, a picture sound, but the image from left to right obvious drawing phenomenon, especially the picture
