这里的“特殊”性指的是电路设计跟常规电路有所不同而言,检修人员对这种电路不了解,按平时的检修思路检修,往往不奏效,费时费力。当你了解到这种“特殊”电路的工作原理后,再遇到这种故障时,检修起来就相对简单多了。现举几个实例供同行参考。例1 机型:康佳T5435型彩电(“雷击”转修机) 故障现象:开机“三无”。据原检修人员讲:电源部分损坏了很多元件,因副电源开关变压器损坏,当地一
Here’s “special” refers to the circuit design is different with the conventional circuit, maintenance personnel do not understand this circuit, according to the maintenance of peacetime maintenance ideas often do not work, time-consuming and laborious. When you understand the working principle of this “special” circuit, and then encounter this failure, the repair is relatively simple. Now give a few examples for peer reference. Example 1 Model: Konka T5435 color TV (“Lightning” repairing machine) Symptom: boot “three no.” According to the original maintenance staff: power supply damaged a lot of components, due to sub-power switch transformer damage, a local
