松下TC-2188(c150机芯)彩电开关电源的检修

松下TC-2188电源的祥细原理 松下TC-2188(c150机芯）彩电开关电源的检修

松下TC-2188彩电的开关电源由于增加了完善的保护电路，结构较复杂，使维修难度大大提高，出现故障时，往往不知如何下手。其实，只要我们真正把电路弄懂吃透，掌握一些检修技巧，监测几处关键点的电压，判断故障元件还是不难的。

首先，我们来分析一下TC-2188S开关电源的电路原理图（如图所示）。我们把高压整流滤波部分、振荡稳压部分、待机控制部分、低压整流滤波部分、保护电路部分一一分开，断开某一个元件，使它们相对独立。然后根据故障现象，确定检修位置，从而可较快地判断故障元件，使维修变难为易。

当彩电开关电源出现故障时。最常见的现象是：（1）开机三无，指示灯不亮。（2）开机三无，指示灯亮闪一下即灭。（3）收看中无规律自动关机。（4）遥控开关机失灵。

当出现上述故障检修时，打开机盖后，首先将万用表拨到R×1K档，用红表笔接显像管石墨层接地线，黑表笔接行偏转线圈一头，测一下电阻值应大于5k以上且有电容充放电现象，说明行管未击穿，大体认为故障出在开关电源部分。

检修时可按以下步骤进行：

一、将R834、R835断开，将D832断开，在C835上并联接入60W/220V灯泡作为假负载。这样就把行负载断开，可以安全地检修开关电源了。试通电，如果灯泡不亮，说明故障确实是出在开关电源部分，可进行下一步检修。

二、切断保护电路。Q826、Q827、Q804，光电耦合器D836、D811，二极管D837、D830，D831、D832、D502、Q805及外围电路组成行、场过流 ，＋B过压、失压保护电路。摘除这部分电路后，对开关电源工作不受丝毫影响。如果没有这部分电路，这个电源就简化多了。保护电路的最后执行元件是Q804，将其摘除后，所有保护功能全部失效。
