    Vizio XVT553SV Sound, no picture

    I am a complete noob who got a Vizio XVT553SV from a friend. It reportedly had sound, but no picture. I have disassembled it and see no obvious bulging caps. I have checked continuity on all the little fuses and, assuming I did it right, they're all fine.
    Where do I start in diagnosing?

    Inverter boards are a good start but the power board cannot be ruled out just yet. Posting pictures would help as well.

      Sorry for the delay. I am now set up to reply quickly.

      Here are two boards, some pics better than others.

      Of the two other full-sized boards, one is the large power supply board and the other has "LED driver" printed on it.

      Please let me know what else I need to show.

        Hold a flashlight to the screen to see if there is a picture.

          Just plugged it in myself, LED backlighting seems to be working (the screen has a light to it, just no picture). I played a movie while shining a flashlight at the screen and looking up close, see nothing. Could the backlighting be overpowering any faint image?
