中文
含义
E008 为音频功放 IC 故障。功放芯片负责驱动扬声器发声,故障时会出现无声音、声音失真或杂音等问题。
常见原因
- 功放过流保护触发
- 扬声器阻抗不匹配
- 功放输出端出现直流偏置
- I2S 音频输入信号丢失
- 功放 IC 热关断
自助排查
- 检查电视音量是否被设置为静音或极低。
- 进入设置菜单切换不同音效模式,观察是否有变化。
- 尝试外接蓝牙音箱或耳机,如外接正常说明功放或扬声器端故障。
- 用万用表测量扬声器阻值(通常为 4Ω 或 8Ω),如开路说明扬声器损坏。
- 若确认功放 IC 故障,需更换主板或功放模块,联系海信售后处理。
English
Meaning
Audio amplifier IC fault. The amplifier chip drives the speakers to produce sound. Failure results in no audio, distorted sound, or noise.
Common Causes
- Amplifier overcurrent protection triggered
- Speaker impedance mismatch
- DC offset on amplifier output
- I2S audio input signal missing
- Amplifier IC thermal shutdown
Self-Check Steps
- Check that the TV volume is not muted or set extremely low.
- Go to the settings menu and switch between different sound modes to see if there is any change.
- Try connecting an external Bluetooth speaker or headphones; if external audio works, the fault is in the amplifier or speakers.
- Use a multimeter to measure speaker resistance (normally 4Ω or 8Ω); an open circuit indicates a damaged speaker.
- If the amplifier IC is confirmed faulty, the main board or amplifier module must be replaced; contact Hisense after-sales service.
