一、保护电路维修技巧采用首先排除微处理器和I2C总线系统故障,测量关键点电压,确定故障范围的方法进行维修。在追踪自检信息和解除保护时,可参照以下方法检修。(一)追踪自检信息,检测相关电路追踪自检信息时,应根据指示灯的颜色和闪烁次数对相应的电路进行检修。该机芯正常时,刚开机时 First, the protection of circuit repair techniques First rule out the microprocessor and I2C bus system failure, measuring the voltage at the key points to determine the scope of the fault method for maintenance. In tracking self-test information and lifting of protection, the following methods can be overhaul. (A) follow-up self-test information, test circuit tracking self-test information, should be based on the color of the indicator light and the number of flashes on the corresponding circuit maintenance. The movement is normal, just boot
