Tip & How-To about Televison & Video
Ever wondered if your radio / TV / Receiver / DVD remote is still working? You've changed the batteries and still it does not seem to operate. Test it like this : Using your digital camera or cellphone camera point the infra red LED of the remote into the camera as if to take a picture of the remote like this:
Operate one of the buttons on the remote and watch the remote through the viewer and you should see this:
The LED will be flashing rapidly if the remote is functioning. This is because the infra red signal sent by the LED is not visible to the naked eye but is to the camera's circuitry. Magic!! Now go try it. You know you want to. ;-) ps This will not work on your vehicles remote fob as it works with radio signals and not infra red light.
