- Take your remote and your cellphone or a camera
- Start the Camera in your phone or the Camera
- Point your remote towards the camera lens
- Press any key of the remote
- Now you’ll see a light just like the above image
If the light is bright and clearly visible then your remote is working just fine! And if its dim and not so bright that means you need to change the batteries. And is still its not showing any light in camera then your remote probably needs to be replaced.
How it works?
Every remote has a Infrared Blaster that send signals to the receiver. We cannot see the light coming from it with naked eyes. However cameras can show us these lights easily!
So next time instead of banging your remote better change the batteries of it!
