TV/VCR remote control checkup

Whenever TV/VCR remote stops working, then most of the time, it is time to change the battery, but sometime, even after changing the batteries, remote does not work. In this case, there could be issue with TV/VCR or Remote sensor. Now as we press the button on remote, we can't see the signal sent from remote or any lights emitting from remote, but if we use our mobile phone video camera, then we can easily see the lights on the head of TV remote. Use the mobile as your second eye, and it will make it clear that whether remote is working properly of not.
