含义
LED指示灯闪烁7次，表示无线模块（WiFi/蓝牙）故障。该代码指电视内置的无线网卡模块通信异常，可能导致无法搜索到WiFi网络、蓝牙遥控器配对失败或无线连接频繁断开。
常见原因
- WiFi/蓝牙模块（如AzureWave AW-CM256SM）固件加载失败或硬件故障
- 模块与主板之间的USB接口信号线接触不良或断路
- 无线天线连接端子松脱或天线本身损坏
- 主板USB供电给无线模块的电压不足或纹波过大
- 软件中无线模块驱动被异常禁用或配置损坏
自助排查
- 在设置菜单中检查WiFi开关状态，尝试关闭再重新打开WiFi/蓝牙功能
- 长按遥控器电源键5秒强制重启电视，观察无线功能是否恢复
- 断开电源2分钟后重新上电，让模块彻底重新初始化
- 如无线模块持续无法工作，可外接USB无线网卡作为临时替代方案
English
Meaning
The LED indicator blinks seven times, indicating a wireless module (WiFi/Bluetooth) failure. This code indicates a communication anomaly with the TV’s built-in wireless card, which may result in inability to detect WiFi networks, Bluetooth remote pairing failures, or frequent wireless disconnections.
Common Causes
- WiFi/BT module (e.g. AzureWave AW-CM256SM) firmware failed to load or hardware damaged
- USB interface signal lines between the module and main board with poor contact or open circuit
- Wireless antenna connector loose or the antenna itself damaged
- Insufficient or excessively noisy USB power delivery from the main board to the wireless module
- Wireless module driver disabled in software or corrupted configuration
Self-Check Steps
- Check the WiFi toggle in the settings menu — try turning WiFi/Bluetooth off and back on
- Force restart the TV by holding the power button on the remote for 5 seconds and observe if wireless recovers
- Unplug the TV for 2 minutes and reconnect to allow the module to fully reinitialize
- If the wireless module persistently fails, use an external USB WiFi adapter as a temporary workaround
