This invention relates to the field of video signal processing and fault diagnosis technology. Addressing the problem that existing video capture chips easily misjudge "no signal" when signal attenuation occurs, making it difficult for users to distinguish between cable quality issues and physical disconnections, this invention discloses an automatic detection method. This method directly connects the hardware detection cable (such as a hot-swappable detection cable HPD or ID pin) of the video interface (HDMI / VGA / DVI) to the GPIO interface of the SoC. The SoC monitors the physical voltage level in real time and correlates it with the image output status of the capture chip. The system diagnoses based on three logical combinations: "image present + voltage level (normal signal)," "no image + no voltage level (physical no signal)," and "no image + voltage level (abnormal / attenuated signal)." This invention effectively improves the robustness of signal detection, assisting users in accurately locating faults caused by cable quality or signal weakening through hardware-level physical feedback, and has significant practical value.
