Thx, but I already know that. I want to trouble shoot a little before I jump to the obvious of replacement. Like wire, ribbons or cords. There is a silver ribbon going from the main board to the T-Con, and a cord connecting the power and main board. Could those be bad?Also, my back lights come on. I see all of them working, they even dim and brighten when I let set and then use the remote. Why do you think they are bad?Is there anything else it could be?Thx
