the question about what is wrong depends upon what the screen does when you first turn it it on. In a very dark room turn it on and watch the screen. There are three possibilities.
first is the screen stays completely black; this is probably a bad inverter board (the video is there but since the back lights are not working you cannot see it). Point a very bright flashlight to the screen to see the video is present.
Secondly the screen lights up slightly; this is likely the T-Con board.
Lastly the screen starts to glow slightly for a couple seconds then goes black; this is usually one of the back light didn't properly light up and the inverter sensed it and shut the rest off. The problem could be either on stage of the inverter board or one of the florescent tubes inside the LCD panel or that stage of the inverter board.
