含义
错误码E300001表示WiFi模块通信异常。该代码表示电视内置WiFi模块初始化失败或在运行时与主控制器失去连接，导致电视无法扫描或连接WiFi网络。
常见原因
- WiFi模块固件挂起，与主控的SDIO/USB接口通信超时
- 无线模块被静电放电（ESD）击穿，导致WiFi MAC地址丢失
- 路由器端WiFi设置变更（信道、加密方式）导致模块无法关联
- 电视机附近存在强RF干扰源（微波炉、无绳电话）
- Android TV系统的WiFi设置数据库损坏
自助排查
- 重启电视和路由器，排除临时性网络故障
- 在设置中关闭WiFi并重新打开，或切换飞行模式后恢复
- 检查WiFi网络是否为2.4GHz频段（5GHz在某些索尼旧型号上兼容性较差）
- 前往设置→网络→重置网络设置，清除已保存的网络配置后重新搜索
English
Meaning
Error code E300001 indicates a WiFi module communication anomaly. This code indicates that the TV’s built-in WiFi module has failed to initialize or has lost connection with the main controller during operation, preventing the TV from scanning or connecting to WiFi networks.
Common Causes
- WiFi module firmware hung, SDIO/USB interface communication with the main controller timed out
- Wireless module damaged by ESD, causing WiFi MAC address loss
- Router-side WiFi settings changed (channel, encryption) preventing association
- Strong RF interference sources near the TV (microwave oven, cordless phone)
- Android TV system WiFi settings database corrupted
Self-Check Steps
- Reboot both the TV and the router to rule out temporary network issues
- Turn WiFi off in settings and back on, or toggle airplane mode
- Check if the WiFi network is on the 2.4GHz band (5GHz compatibility is lower on some older Sony models)
- Go to Settings → Network → Reset network settings, clear saved networks, and search again
