If the other device fails to make a connection, then you’ll have to replace the cable with a new one.
If the cable is in working condition, unplug it and reconnect it after waiting for at least 5 minutes. Check to see whether a connection is established.

Did you connect your laptop to a functioning TV HDMI port? Check the port to see if there’s any damage to the port.
