Tech Tip: How to tell if your remote is working?

If you ever had problems with your TV remote, you probally would want to read this tech tip.  How do you tell if your remote is working or there's something else wrong?  Is the battery dead or is the TV remote sensor broken?

The quickest way to see if the remote is working is to get any camera or video camera and look at the screen when you press a button on the remote.  If you see a bright purplish light shining, then the remote is working and transmitting the infrared light. 

In the picture below, you can see one of the LEDs shining bright when a button on the remote is pressed.  Normally the human eye can not see it but the sensor on any camera can see it very clearly.

Below you can see the right LED shining while the left LED is off.
