   蜂鸣器 拔下电源线，用镊子短路三脚插头的两个供电插脚，测另一头三芯插孔的两个供电插孔间的电阻为零，拿开镊子时电阻变为无穷大，说明电源供电线完好，不存在开路和短路故障。测电脑电源各输出脚对地间的电压全部为0V，在紫线与黑线间测不到5V待机电压，绿线与黑线间电压也为0V。拆开电脑电源盒，测电源输入端正反向电阻均为无穷大，测TUBE6A保险丝烧断。测C121两端正向电阻为无穷大，反向电阻为487Ω。C122两端正反向电阻都为13Ω。沿电路找到并联在C121两端的压敏保护电阻RV121(TVR10241X)由黄色变为红色，并被烧缺一块。RV122(TVR10241X)直接被击穿为13Ω，但仍为黄色。测查所有晶体管和大功率管及输出电路的所有整流二极管和滤波电容，对可疑元件逐一拆下检测，未找到击穿、漏电或开路元件。由电路的连接方式可以推断出，TVR10241X的保护电压应该是MYC10K471保护电压的一半。用一个MYG10K471彩电整流滤波输出端的保护压敏电阻，一脚焊接到C121的正极，一脚焊接到C122的负极，将两个串联保护的压敏电阻改为一个，以提高保护的灵敏度和可靠性，更换保险。通电测C121和C122两端的电压分别依次为156V，MYG10K471两端的电压为313V，比彩电中该电阻两端电压298V高5V。
