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

1. 功放过流保护触发
2. 扬声器阻抗不匹配
3. 功放输出端出现直流偏置
4. I2S 音频输入信号丢失
5. 功放 IC 热关断

自助排查

1. 检查电视音量是否被设置为静音或极低。
2. 进入设置菜单切换不同音效模式，观察是否有变化。
3. 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。
4. 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。
5. 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

1. Amplifier overcurrent protection triggered
2. Speaker impedance mismatch
3. DC offset on amplifier output
4. I2S audio input signal missing
5. Amplifier IC thermal shutdown

Self-Check Steps

1. Check that the TV volume is not muted or set extremely low.
2. Go to the settings menu and switch between different sound modes to see if there is any change.
3. Try connecting an external Bluetooth speaker or headphones; if external audio works, the fault is in the amplifier or speakers.
4. Use a multimeter to measure speaker resistance (normally 4Ω or 8Ω); an open circuit indicates a damaged speaker.
5. If the amplifier IC is confirmed faulty, the main board or amplifier module must be replaced; contact Hisense after-sales service.
