在本机中,除公共通道和公用部分外,左右两路所用元器件都是相同的,叙述时以左路为例. (一)整机无声收音、放音均无声,故障大多在电源部分(见图1). 常见故障为: 1.保险丝BX_1、BX_2烧断.有时在开机或关机的瞬间,保险丝被浪涌电流烧断. 2.全波整流电路的次级绕组中心轴头断路,无电压输出.
In this machine, in addition to public access and public parts, the left and right two components are the same, the narrative to the left as an example. (A) the whole machine silent radio, playback are silent, most of the failure in the power section (See Figure 1.) Common faults are: 1. Fuse BX_1, BX_2 blown sometimes fuse at the moment of power on or off, the fuse is blown inrush current 2. The secondary winding of the full-wave rectification circuit is disconnected from the central axis, No voltage output.
