Have you ever had a remote control that you knew just wasn't working right? You know, you point it at the TV and press the buttons, but nothing happens. You try new batteries, but you still get no response. So, how do you know if the remote is broken or not? After this check you will be able to tell if your remote is bad or if the TV remote sensor is not working right. Here is a visual check you can perform and you can show off to your family.
In order to test the remote, you need is a regular digital camera with a screen on the back or a cell phone with a built in camera will work. Here is what you do:
1. Turn on the digital camera or the cell phone to camera.
2. Point the remote at the lens of the camera so that you can see the remote on the camera's digital screen.
3. Then, press a button on the remote any button will do, and look at the camera screen. If the remote is working, you should be able to see a light blinking on the end of the remote each time you press the button. Again, if you see the light, the remote is working. This is a good indication that your TV sensor is bad.
How does that work, you ask? Well, remote controls use infrared light to send the signal to your TV, but human eyes cannot see the light. If you look at the end of your remote, you will see absolutely nothing. I do not know if this is harmful but do not get to close to the light emitting diode or the remote, it could cause some harm to your eyeballs.
Digital cameras pick up a lot more light or (here is some Tech Talk) have a greater sensitivity to the light spectrum. So, when you point the remote at the camera and press a button, the lens on the camera sees the infrared light and displays it on the camera screen. Cool, huh? Go and give it a try.
If you do not have a bad remote you can still "WOW" your friends and neighbors just don’t tell then where you got this information say "I discovered it."
