ERR 2 - 索尼 电视

中文

含义

错误码ERR 2表示USB设备相关故障。该代码表示声吧检测到USB端口异常——可能是USB设备不兼容、供电过载或USB接口物理损坏，导致USB音频播放或固件更新功能异常。

常见原因

1. USB存储设备格式不兼容（如NTFS而非FAT32/exFAT）
2. USB设备供电需求超过声吧USB端口输出能力（通常仅500mA）
3. USB接口内部触点短接或物理损坏，触发过流保护
4. USB音频文件编码格式声吧不支持（如DSD、FLAC 192kHz以上）
5. USB延长线质量不佳导致信号衰减，设备无法识别

自助排查

1. 拔掉USB设备，检查ERR 2是否消失——如消失则USB设备或文件有问题
2. 将USB存储设备格式化为FAT32，存入标准MP3或WAV格式文件测试
3. 更换USB设备测试，避免使用USB 3.0高速U盘（部分声吧兼容性较差）
4. 不连接任何USB设备时仍报ERR 2，可能是USB接口硬件故障需送修

English

Meaning

Error code ERR 2 indicates a USB device-related fault. This code indicates that the soundbar has detected a USB port anomaly — possibly an incompatible USB device, overcurrent condition, or physical damage to the USB port — affecting USB audio playback or firmware update functionality.

Common Causes

1. USB storage device format incompatible (e.g. NTFS instead of FAT32/exFAT)
2. USB device power draw exceeds the soundbar’s USB port output capacity (typically 500mA)
3. USB port internal contacts shorted or physically damaged, triggering overcurrent protection
4. USB audio file encoding format not supported by the soundbar (e.g. DSD, FLAC above 192kHz)
5. Poor quality USB extension cable causing signal degradation, device not recognized

Self-Check Steps

1. Remove the USB device and check if ERR 2 disappears — if it does, the USB device or its files are the issue
2. Format the USB storage device to FAT32 and test with standard MP3 or WAV files
3. Try a different USB device, avoiding USB 3.0 high-speed drives (some soundbars have poor compatibility)
4. If ERR 2 persists with no USB device connected, the USB port may have a hardware fault requiring repair
