Sometimes a reset of the audio connection can help recognize the audio signal. If none of these solutions work, check the audio settings on your connected device, as they might need to be configured for HDMI output.
Why does my TV display “No Signal” with the HDMI input?
When your TV displays “No Signal,” it usually means that it is not receiving a proper video feed from the connected device. First, double-check the HDMI connection to ensure that it is securely plugged into both the TV and the device. If the cable is secure, try switching to a different HDMI input on the TV or using another device to test the functionality of the HDMI port.

Check the device settings to ensure that HDMI output is enabled. Additionally, if possible, try using a different HDMI cable, as sometimes the issue could be related to a defective cable.
What can I do if my LG TV HDMI port is not working at all?
If you suspect that the HDMI port on your LG TV is not working at all, start by testing it with multiple HDMI devices and cables. If multiple devices yield the same result, it may indicate a fault in the HDMI port itself. You can also try connecting a different media source that you know works with other TVs to see if there’s any response.
If the HDMI port remains unresponsive after multiple tests, consider performing a factory reset on your TV to resolve any potential software-related issues. If none of these troubleshooting steps resolve the problem, you may need to consult an LG service center or a professional technician for advice on repairs or replacements.
