Since screen has backlight yet no image/ display or graphics appears that points to t-con board failure that provides video data to LCD panel circuitry, t-con board would be located under metal shield at top or bottom center of rear of LCD panel, swapping the t-con board (also know as FRC, frame rate control board) is only option to proceed, please check with following board supplier to get required identical t-con board..
