I can’t find the power button on the tv to reset it

You need to do a flashlight test, Turn it on and hold a flashlight up to the screen. If you can see an image then either the power supply board or the backlights are bad. If you see an image then disconnect the cable going from the power supply board to the main board, If the back lights come on then you need to replace the board. If not then its most likely the backlights need replaced.
