    Toshiba, 46ul605u, no backlights

    Hi guys
    I tested the backlights and they are lighting up at about 80v. I am getting a signal at the backlight on. I need a schematic if anyone has one or help identifying the swiching ic for the backlight power. Many thanks.

      Please upload good clear pictures of the whole backside of the TV showing all the boards, also the straight shot pictures of the whole top and bottom side of the power supply board so we can see what we are dealing with.
