中文
含义
LED指示灯闪烁9次，表示固件（Firmware）异常。该代码表示电视的操作系统或底层固件在启动过程中检测到严重错误，可能由于固件更新失败、系统文件损坏或启动分区损坏导致无法正常进入系统。
常见原因
- 固件OTA更新过程中断电或网络中断，导致升级不完整
- eMMC存储中的系统分区文件损坏或产生坏块
- 第三方应用冲突导致系统关键服务崩溃，Safe Mode无法修复
- 使用非官方固件或跨区域固件刷写导致签名验证失败
- Bootloader损坏或启动参数配置错误
自助排查
- 尝试强制重启：拔掉电源线等待60秒后重新上电
- 使用索尼官方固件U盘恢复模式——将固件文件放入FAT32格式U盘根目录，插入USB口后同时按住电源键和音量减键上电
- 如能进入安全模式，尝试恢复出厂设置（设置→设备偏好设置→重置）
- 如以上方法无效，需联系索尼售后使用专用工具重新刷写固件
English
Meaning
The LED indicator blinks nine times, indicating a firmware anomaly. This code indicates that the TV’s operating system or underlying firmware has detected a critical error during boot. It may be caused by an interrupted firmware update, corrupted system files, or a damaged boot partition, preventing the TV from entering the system normally.
Common Causes
- Power outage or network interruption during OTA firmware update, resulting in an incomplete upgrade
- Corrupted system partition files or bad blocks in eMMC storage
- Third-party app conflict causing critical system services to crash, not recoverable in Safe Mode
- Unofficial or cross-region firmware flashed, causing signature verification failure
- Bootloader damaged or boot parameters misconfigured
Self-Check Steps
- Try a forced restart — unplug the power cord, wait 60 seconds, then reconnect
- Use Sony official USB recovery mode — place the firmware file on a FAT32 USB drive, insert it, then hold the power and volume-down buttons simultaneously while powering on
- If Safe Mode is accessible, try a factory reset (Settings → Device Preferences → Reset)
- If none of the above works, contact Sony support for specialized firmware reflash tools
