E09 - 飞利浦 电视

中文

含义

USB过流保护触发。USB端口因外接设备电流过大而自动切断供电，无法识别USB设备。

常见原因

  1. 插入的USB设备功耗超出电视USB端口供电能力（通常为500mA）
  2. USB外接硬盘未使用独立供电——大容量硬盘启动瞬间电流过高
  3. USB端口内部金属触点短路或潮湿氧化
  4. USB延长线或HUB质量差导致线路短路
  5. 外接USB设备内部短路触发端口过流保护

自助排查

  1. 拔下所有USB外设，检查USB端口内是否有异物或金属碎屑
  2. 更换低功耗USB设备（如U盘）测试端口是否恢复
  3. 大容量移动硬盘应使用独立外接电源而非依赖电视USB供电
  4. 检查USB线缆是否破损或接头氧化
  5. 如所有设备均触发过流保护，可能是端口电路故障需维修

English

Meaning

USB overcurrent protection triggered. The USB port has been cut off due to excessive current draw from a connected peripheral.

Common Causes

  1. Connected USB device draws more power than the TV port can supply (typically 500mA)
  2. External hard drive without its own power supply — inrush current exceeds the port limit on spin-up
  3. Short circuit or corroded contacts inside the USB port socket
  4. Poor-quality USB extension cable or hub causing a short
  5. Internally shorted USB device triggering port-level overcurrent protection

Self-Check Steps

  1. Disconnect all USB devices and inspect the TV’s USB port for debris or bent pins
  2. Test with a low-power device (e.g., a standard USB flash drive) to see if the port recovers
  3. Use an externally powered hard drive enclosure instead of bus-powered for high-capacity drives
  4. Examine the USB cable for damage or corroded connectors
  5. If every device triggers overcurrent, the port circuitry may need repair
