Tv Turns On Then Goes Black. Not Power Board.

My 47LX6500 LG LED TV turns on, the logo shows for 1-3 seconds, then the screen goes blank while the power stays on. I replaced the power board, but this did not fix the problem. Same thing would happen. There doesn't seem to be any sound either, and I have not been able to see anythign on the screen using a flashlight. There are only 3 boards in the back of the tv (power, control, and main board). previous help sent a link to an LCD repair video that only suggested replacing the power board.
