故障现象:“三无”。据客户反映,该机在正常收看中突然发出“啪、啪”的巨响,急忙用遥控关机却关不死,当去关电源开关时却遭到电击,未能关掉,赶紧拔下了电源插头。分析与检修:根据客户陈述,结合检修经验,推断此故障不是一般的高压打火,应是高压包(行输输出变压器)破裂,造成高压
Symptoms: “three no.” According to the customer, the machine suddenly issued in the normal watch “pop, pop” loud noise, but quickly shut down with the remote control is not dead, when the switch to the power switch was shocked, failed to turn off and quickly unplug the power plug. Analysis and Maintenance: According to customer statements, combined with maintenance experience, concluded that the failure is not a general high-pressure ignition, should be high-voltage packet (line output transformer) rupture, resulting in high pressure
