Try shine a bright light to the screen at boot or when toggling power button to check if you have a dimmed out image or no image at all. In first scenario there’s a higher chance of a board backlight issue whereas in the second an Lcd failure would be more likely. Yet, we are just talking about probabilities, without known good parts or tests one can never be 100% sure.
