Most televisions sets come with a remote control, and in fact, with today's TVs it's not always easy to turn the set on, turn up the volume or change the channel without it. If your TV's remote control is not working, don't throw it across the room until you have ruled out all the logical reasons it may be dead.

Scrutinize the remote buttons. Remove any dirt and grime that may make the buttons sticky. Check all of the buttons individually to make sure they are not stuck in the down position by pressing them one at a time.
Verify that the infrared light is working. Look through the lens of a digital camera. Point the remote at the camera and press any button on the TV remote. If the infrared light is working, you will see red coming from the transmitter light.
