WON TURN ON
For the first step, try using the button on the TV itself.
Secondly, check if the power cord is snug, and not burnt. Sometimes after a blackout, there would be a power surge, and that might burn your plug.
If both doesn't work, the fuse in your TV may be blown, or the Power Supply may also be burnt too. If this happens, you're going to have to hire an expert to help replace the broken parts.
Note that in some TV models, the fuse can be replaced by users. If this is your case, try checking the fuse to see if it's blown or not.
