-如按上述操作背光仍然没反应，则推测可能硬件电路故障。
-===== 2.产品上电测试背光亮，但是无显示画面        =====
-背光亮说明模块已经正常上电，检查是否因为供电电压不足或者上位机未点击开始屏显，必要时使用万用表/示波器/逻辑分析仪等必要的工具对信号进行分析检测，并与我司技术人员联系获取帮助。
-===== 3.'''上位机显示无可用屏幕''' =====
-检查背光是否点亮，再检查设备管理器是否检测到屏幕接入，如果拔插几次或者更换电脑接口和数据线，还是检查不到可与我司技术人员联系获取帮助。
-===== 4.'''点击开启屏显后屏幕不亮''' =====
-先检查背光是否点亮，未点亮可能供电不足，更换电脑接口或数据线后再尝试，检查亮度是否太低，屏幕像素是否正确，主题是否选择。
