The HDMI source will not show if no HDMI input is detected.
Check that the HDMI cable is securely attached at both ends, and the HDMI device is turned on.
Try using a different HDMI port on the TV if the problem persists.
Can you test the HDMI device on a different TV?
Based on the information you have provided so far, it is likely that the HDMI device has a fault and is not outputting a signal. If this is confirmed then it will need to be repaired or replaced.
