Good evening asisBasu ,

Have you check each of your connections to the TV to make sure that the connections are secure?

Yes. The front indicator light by the power button is blinking.

I am not an expert on this, but try pulling the plug for a minute or two and then plug it in again... hopefully that will 'reboot' it.
