本文所说的行扭是这样一种故障,即电视机的图象没有失步,并且清晰度和伴音都基本正常,只是图象左右扭曲的故障。行扭是一种比较难查的故障,也就是人们常说的软故障。它的扭曲现象粗看起来似乎一样,都是在左右扭曲,而引起行扭的原因却是多种多样的,涉及的范围非常广泛。针对上述情况,本文将介绍一种不用示波器和毫伏表,仅仅依靠电视机自身的调节旋钮并配合万用表来快速判断故障部位的方法。行扭现象主要是由下述四部分电路的故障所造成。
Twist line in this article is such a failure, that is, the TV picture is not out of step, and sharpness and sound are basically normal, but the image is distorted around the failure. Twist is a more difficult to check the fault, that is, people often say that the soft fault. Its distortions appear to be the same on the one hand, and on the other hand, they all distort around. The reasons for their twisting are varied and involve a very wide range of issues. In view of the above situation, this article will introduce a method without oscilloscope and millivoltmeter, just rely on the TV’s own adjustment knob and with the multimeter to quickly determine the fault location. Line torsion phenomenon is mainly caused by the failure of the following four parts of the circuit.
