含义
康佳电视检测到 HDMI EDID（扩展显示标识数据）读取异常。E015 错误代码表示电视无法正确读取 HDMI 输入源的 EDID 信息，或 HDMI 接口与外部设备之间的 DDC 通信失败。连接 HDMI 设备时可能无图像、图像分辨率异常或间歇性黑屏。
常见原因
- HDMI 线缆质量不良或规格不够（HDMI 1.4 线用于 4K 信号），导致 DDC 时钟通道（SCL）受干扰。
- HDMI 接口的 5V 供电引脚接触不良，外部设备无法检测到电视。
- 主板上的 HDMI EDID EEPROM 芯片损坏或数据丢失。
- HDMI 接口静电保护 IC（ESD diode）击穿短路，将 DDC 信号拉低。
- HDMI 连接器的插座引脚焊接不良或弹片变形。
- 外部源设备输出格式（如色彩空间、刷新率）超出电视的 EDID 能力范围。
自助排查
- 更换一条高质量的 HDMI 线缆（建议 HDMI 2.0 或更高规格），排除线缆故障。
- 将 HDMI 设备连接到电视的其他 HDMI 接口测试——如果其他接口正常，则是特定接口问题。
- 将 HDMI 设备连接到另一台电视或显示器测试——确认源设备输出正常。
- 拔掉所有 HDMI 设备，断电等待 2 分钟后重新上电，再逐一连接 HDMI 设备测试。
- 在源设备上降低输出分辨率（如从 4K 降至 1080p）或调整刷新率（从 60Hz 降至 50Hz），观察是否恢复正常。
English
Meaning
The Konka TV has detected an abnormal HDMI EDID (Extended Display Identification Data) read. Error code E015 indicates that the TV cannot correctly read the EDID information from the HDMI input source, or DDC communication between the HDMI interface and the external device has failed. When connecting an HDMI device, there may be no picture, abnormal resolution, or intermittent black screen.
Common Causes
- Poor-quality or underspecified HDMI cable (e.g., HDMI 1.4 cable used for 4K signal), causing interference on the DDC clock line (SCL).
- Poor contact on the 5V power pin of the HDMI connector, preventing the external device from detecting the TV.
- The HDMI EDID EEPROM chip on the motherboard is damaged or has lost data.
- The ESD protection diode on the HDMI port is shorted, pulling the DDC signal lines low.
- Cold solder joints or deformed spring contacts on the HDMI connector socket.
- The output format from the external source (e.g., color space, refresh rate) exceeds the TV’s EDID capability.
Self-Check Steps
- Replace with a high-quality HDMI cable (HDMI 2.0 or higher recommended) to rule out cable issues.
- Connect the HDMI device to a different HDMI port on the TV — if other ports work, the problem is port-specific.
- Test the HDMI device on another TV or monitor to confirm the source device output is normal.
- Disconnect all HDMI devices, unplug the TV for 2 minutes, then reconnect and test one HDMI device at a time.
- On the source device, lower the output resolution (e.g., from 4K to 1080p) or change the refresh rate (from 60Hz to 50Hz) and see if the issue resolves.
