E200001 - 索尼 电视

中文

含义

错误码E200001表示音频系统故障。该代码由音频子系统自检触发，表示电视的音频处理链路——从SoC音频输出到功放芯片输入端——存在信号异常或设备配置错误。

常见原因

1. 音频DAC/编解码器初始化失败，I²S时钟信号丢失
2. 功放芯片（如TI TAS5751M）Mute引脚被异常拉高
3. 音频总线I²C通信故障，功放寄存器无法正常配置
4. 系统音频策略错误将输出路由到已断开的HDMI ARC通道
5. 音频DSP固件加载失败，均衡器或音效处理未初始化

自助排查

1. 切换音频输出模式：电视扬声器→蓝牙耳机→HDMI音响，判断哪一路有声音
2. 进入设置→声音→恢复声音设置默认值
3. 更新电视固件到最新版本，修复已知音频驱动问题
4. 如所有输出通道均无声，可能是SoC或功放硬件故障，需送修

English

Meaning

Error code E200001 indicates an audio system failure. This code is triggered by the audio subsystem self-test, indicating a signal anomaly or device configuration error in the TV’s audio processing chain — from the SoC audio output to the amplifier chip input stage.

Common Causes

1. Audio DAC/codec initialization failed, I²S clock signal lost
2. Amplifier IC Mute pin (e.g. TI TAS5751M) abnormally pulled high
3. I²C communication failure on the audio bus, amplifier registers not properly configured
4. System audio policy incorrectly routing output to a disconnected HDMI ARC channel
5. Audio DSP firmware failed to load, equalizer or sound processing not initialized

Self-Check Steps

1. Cycle through audio output modes — TV speakers → Bluetooth headphones → HDMI audio system — to identify which channels have sound
2. Go to Settings → Sound → Reset sound settings to defaults
3. Update TV firmware to the latest version to resolve known audio driver issues
4. If all output channels are silent, the SoC or amplifier may have a hardware fault — send for repair
