Sometimes it happens that TV or any gadget remote does not respond and several thoughts start coming into your mind that what can be wrong. Most of the time its dead battery but how can you check that your remote is working or not or there is sometime wrong with TV itself. If you have a camera phone or any digital camera, take it out and its time to make some movie of your remote control! It may sound funny but it’s the simplest way to check if your remote is working or not. While looking at your phone thru camera, press any button in remote and you should see the remote sensor glowing brightly. See in the photo above which is my AC remote and as you can see the sensor is emitting light which means the remote is OK. If the light is very dull then you need to change the battery and if there is no light then battery is dead or remote is not working anymore.
