Power went out today and the TV is not turning on now
Most likely when the power came back on, there was a surge that damaged the power supply board in your TV. If your TV is completely dead with no blinking or standby lights, then the power supply is bad.
The power supply is the first board that the plug from the wall is going into.
You can check this by taking the back cover off and check for capicators that have gone bad. These will be capicators that look bubbly on the tops that are budging out. If you see any and know how to solder, replace these capicators with the correct voltage and Farad readings that are usually listed on the capicators themselves. Make sure to mark which side the white stripe on the side of the capacitor is as the orientation is very important.
Replacing the capicators is usually a cheap fix but if you do not want to or cannot solder the capicators or if you do not spot any bad capicators, just replace the whole power supply board. This can be done by just unscrewing it off the LCD panel, disconnecting the connections to and from the board, replacing the new board, reconnecting, and screwing back in the new board with the same screws.
