If your remote controlled equipments like TV,DVD etc are not functioning with remote button press, How do you know the problem is with your equipment or your remote?Almost all people know how to inspect the remote control unit of TV,DVD etc. This post is meant for minority of people who don't know that.
As you know remote control unit is producing infrared rays in pulse form on each press of any buttons. unfortunately infrared light is not visible with naked eye. Take your Mobile phone camera and view the infrared LED through the camera.Press any button and see the infrared light produced from the remote LED. If you bring it near a radio and press you can hear some pulse voice also.
See the video taken in a mobile phone,which make the infrared light visible
