含义
错误码E100001表示背光系统故障。该代码由系统自检程序在启动过程中检测到背光LED灯条或驱动电路异常时生成，与1次闪烁代码同属背光相关故障但提供了更精确的诊断信息。
常见原因
- 背光LED灯条中一组或多组LED开路或短路
- 背光驱动升压转换器输出电流超出阈值
- 背光LED灯条正向电压（VF）与驱动板设定值不匹配
- 驱动板LED电流均衡电路失效
- 背光回检电路检测到电流异常反馈
自助排查
- 进入工程模式查看背光错误日志中具体故障参数
- 使用LED灯条测试仪逐个检测灯条是否正常发光
- 检查驱动板输出端有无明显短路或打火痕迹
- 记录报错时电视使用时长（小时），判断灯条是否自然老化
English
Meaning
Error code E100001 indicates a backlight system failure. This code is generated by the system self-test routine when it detects an anomaly in the backlight LED strips or driver circuit during startup. While related to the same backlight subsystem as the 1-blink indicator, it provides more precise diagnostic information.
Common Causes
- One or more LED groups in the backlight strip open-circuit or short-circuit
- Backlight driver boost converter output current exceeds the threshold
- Forward voltage (VF) of the LED strips does not match the driver board configured value
- LED current balancing circuit on the driver board failed
- Backlight return detection circuit received abnormal current feedback
Self-Check Steps
- Enter service mode and review the backlight error log for specific fault parameters
- Use an LED strip tester to check each strip for normal illumination
- Inspect the driver board output terminals for visible shorts or arcing marks
- Note the TV’s cumulative operating hours at the time of the error to assess whether the strips have naturally aged
