含义
创维电视检测到 HDMI 输入信号异常，E11 代码表示指定的 HDMI 端口未检测到有效的信号输入或识别到连接异常。HDMI 接口支持音视频同时传输，并带有热插拔检测（HPD）引脚用于设备连接状态识别。此错误通常表示外部设备未正确输出信号、HDMI 线材故障或端口 ESD 损坏。
常见原因
- 外部信号源设备（机顶盒、游戏机、电脑）未开机或处于待机状态，未输出 HDMI 信号。
- HDMI 线材损坏——内部断线、插头端子弯曲或线缆过长导致信号衰减。
- 电视 HDMI 端口内部引脚受损，其中 HPD（第 19 脚）或 TMDS 数据线接触不良。
- 信号源设备的 HDMI 输出分辨率或刷新率超出电视的支持范围。
- HDMI 端口的静电防护器件（ESD diode）被静电击穿短路，导致端口检测异常。
- 电视系统软件中 HDMI EDID 数据读取异常，与外部设备无法完成握手。
自助排查
- 确认外部信号源设备已开机并处于正常工作状态，尝试切换输入源确认 HDMI 端口选择正确。
- 尝试其他 HDMI 线材，优先使用带有 HDMI 认证标志的线缆，线长建议不超过 5 米。
- 将 HDMI 设备连接到电视的其他 HDMI 端口，排除特定端口故障的可能性。
- 拔下 HDMI 线，检查线缆两端插头是否有弯曲或损坏的针脚，清洁插头后重新插入。
- 降低信号源设备的输出分辨率至 1080p 或关闭 HDR 输出，排除格式不兼容问题。
English
Meaning
The Skyworth TV has detected an abnormal HDMI input signal. Code E11 indicates that no valid signal is detected on the specified HDMI port, or a connection anomaly has been identified. The HDMI interface supports simultaneous audio and video transmission and uses a Hot Plug Detect (HPD) pin for device connection status. This error typically indicates that the external device is not outputting a signal correctly, the HDMI cable is faulty, or the port has ESD damage.
Common Causes
- The external source device (set-top box, game console, PC) is not powered on or is in standby mode and not outputting an HDMI signal.
- The HDMI cable is damaged — internal broken wires, bent connector pins, or excessive cable length causing signal attenuation.
- The pins inside the TV’s HDMI port are damaged, particularly the HPD pin (pin 19) or TMDS data lines with poor contact.
- The output resolution or refresh rate from the source device exceeds the TV’s supported range.
- The ESD protection diode on the HDMI port has been shorted by electrostatic discharge, causing abnormal port detection.
- The TV system software has failed to read the HDMI EDID data correctly, preventing handshake completion with the external device.
Self-Check Steps
- Confirm that the external source device is powered on and operating normally. Try switching input sources to verify the correct HDMI port is selected.
- Try a different HDMI cable, preferably one with HDMI certification markings, and keep the cable length under 5 meters.
- Connect the HDMI device to a different HDMI port on the TV to rule out a specific port fault.
- Disconnect the HDMI cable and inspect the plugs on both ends for bent or damaged pins. Clean the connectors and reinsert.
- Lower the output resolution of the source device to 1080p or disable HDR output to rule out format incompatibility.
