ERR 4 - 索尼 电视

中文

含义

错误码ERR 4表示网络连接故障。该代码表示声吧无法连接到WiFi网络或与索尼云服务建立通信，可能导致流媒体音乐服务（如Spotify Connect、Apple AirPlay）、多房间音频同步和固件自动更新功能不可用。

常见原因

1. 路由器SSID广播关闭或WiFi网络设置为隐藏网络
2. WiFi密码输入错误，保存了错误的凭证
3. 声吧距离路由器过远，2.4GHz信号衰减导致连接不稳定
4. 路由器开启了MAC地址过滤，声吧的MAC未在白名单中
5. 路由器信道设置与声吧WiFi模块支持的频段不匹配（如使用了DFS信道）

自助排查

1. 在声吧设置中删除已保存的WiFi网络，重新扫描并输入密码
2. 将声吧移近路由器（5米以内）测试，排除信号覆盖问题
3. 重启路由器后待完全启动再进行声吧网络连接
4. 尝试使用索尼Music Center App重新配置网络连接，而非声吧面板操作

English

Meaning

Error code ERR 4 indicates a network connection failure. This code indicates that the soundbar cannot connect to a WiFi network or establish communication with Sony cloud services, which may affect streaming music services (such as Spotify Connect, Apple AirPlay), multi-room audio sync, and automatic firmware updates.

Common Causes

1. Router SSID broadcast disabled or WiFi network set to hidden
2. Incorrect WiFi password saved on the soundbar
3. Soundbar too far from the router, 2.4GHz signal degradation causing unstable connection
4. Router MAC address filtering enabled, soundbar’s MAC not whitelisted
5. Router channel setting incompatible with the soundbar’s WiFi module band support (e.g. DFS channels)

Self-Check Steps

1. Delete the saved WiFi network in soundbar settings, rescan, and re-enter the password
2. Move the soundbar closer to the router (within 5 meters) to rule out signal coverage issues
3. Restart the router and wait for it to fully boot before reconnecting the soundbar
4. Try using the Sony Music Center app to reconfigure the network connection rather than the soundbar panel controls
