E100001 - 索尼 电视

中文

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

1. 背光LED灯条中一组或多组LED开路或短路
2. 背光驱动升压转换器输出电流超出阈值
3. 背光LED灯条正向电压（VF）与驱动板设定值不匹配
4. 驱动板LED电流均衡电路失效
5. 背光回检电路检测到电流异常反馈

自助排查

1. 进入工程模式查看背光错误日志中具体故障参数
2. 使用LED灯条测试仪逐个检测灯条是否正常发光
3. 检查驱动板输出端有无明显短路或打火痕迹
4. 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

1. One or more LED groups in the backlight strip open-circuit or short-circuit
2. Backlight driver boost converter output current exceeds the threshold
3. Forward voltage (VF) of the LED strips does not match the driver board configured value
4. LED current balancing circuit on the driver board failed
5. Backlight return detection circuit received abnormal current feedback

Self-Check Steps

1. Enter service mode and review the backlight error log for specific fault parameters
2. Use an LED strip tester to check each strip for normal illumination
3. Inspect the driver board output terminals for visible shorts or arcing marks
4. Note the TV’s cumulative operating hours at the time of the error to assess whether the strips have naturally aged
