You have main board problem, as to what it is at this point I do not know.
You can try cooling and heating, press on the board, etc. to see if it will do anything.
You can also check to see which command signal to the power supply board is missing, also try diconnecting the T-Con from the main board to see if the backlights will come on.

i got nothing with the heating/cooling and pressing on the board. I was thinking main board issue. I'm going to order on and cross my fingers
