1. The laptop doesn't send a signal.
2. The cable is defective.
3. The TV doesn't process the signal.
So it starts with a process of elimination to find the culprit. It's only the laptop if another hdmi source is shown on the TV with the same cable, and the laptop doesn't work either on another TV with another cable.
Did you check the user manual of your (unknown to us) laptop to see how to activate the hdmi-port?
