松下MX—3机芯电源电路,虽然属于串联型开关电源,但同以往常见的串联型开关电源相比,却有其独特性,如对其独特性不了解,易在检修时走入误区,陷入困境。现从实用检修的角度,把在检修实践中得到的经验和体会总结出来,供同行参考。一、松下MX—3机芯电源电路特点 1.主板不带电的串联型开关电源:以往的串联型开关电源,主板地端都带有220V交流电,在检修时易发生电击事故。而MX—3机芯电源电路设计的确有其 Panasonic MX-3 movement power circuit, although a series-type switching power supply, but with the previous series of common switching power supply, but it has its uniqueness, such as its uniqueness do not understand, easy to go wrong in the repair, In trouble. From a practical maintenance point of view, the experience gained in the overhaul and experience summed up for peer reference. First, the Panasonic MX-3 movement power circuit features 1. Motherboard uncharged series switching power supply: In the past series-type switching power supply, the motherboard ground with 220V AC, prone to electric shock in the repair. The MX-3 movement power circuit design does have it
