中文
含义
LED指示灯闪烁8次，表示散热风扇故障或系统过热。该代码表示电视内置散热风扇停转、转速异常或温度传感器检测到关键组件过热，如不及时处理可能导致永久性硬件损坏。
常见原因
- 散热风扇轴承干涩或卡死，导致完全停转或转速严重不足
- 风扇驱动电路MOS管击穿，风扇供电线路无输出
- 风扇连接器松动脱落，或连接线被异物缠绕
- 通风口被灰尘堵塞或电视放置在密闭空间导致散热不良
- 温度传感器本身故障，误报过热状态
自助排查
- 检查电视通风口是否被遮挡，确保四周至少留有10cm散热空间
- 听风扇运转声音：如完全无声可能风扇卡死，如有异常噪音则轴承磨损
- 断电后用压缩空气清理散热器和风扇上的积灰
- 如风扇完全停转且清理无效，需更换同规格散热风扇
English
Meaning
The LED indicator blinks eight times, indicating a cooling fan failure or system over-temperature condition. This code indicates that the TV’s built-in cooling fan has stopped, is running at abnormal speed, or the temperature sensor detects critical component overheating. Left unattended, this may lead to permanent hardware damage.
Common Causes
- Fan bearing seized or dried out, causing the fan to stop completely or spin at severely reduced speed
- Fan driver circuit MOSFET shorted, no power output to the fan
- Fan connector loose or disconnected, or wires tangled by foreign objects
- Vents clogged with dust or the TV placed in an enclosed space with poor airflow
- Temperature sensor itself faulty, falsely reporting an over-temperature state
Self-Check Steps
- Verify that the TV vents are unobstructed and there is at least 10cm clearance on all sides
- Listen for fan operation — complete silence suggests a seized fan, unusual noise indicates bearing wear
- Power off and use compressed air to clean dust from the heatsinks and fan blades
- If the fan has completely stopped and cleaning does not help, replace it with an equivalent model
