Question about Vizio Televison & Video

My tv model e470-a0 vizio turns off and on with the backlight and the vizio on screen logo is crystal clear on startup. No picture and sound other than some very very faint scrambled lines towards the upper screen. No dust very clean. No bulged capacitors. Wiggled most components. Unplugged rc connector with no change.

My screen is flickering on and off on Vizio LCD TV? I was wondering if it was the main board or the T-Con board.
