I picked up this Vizio a month or so back from a gal who said it had been fine until the cable guy did something on/in her house. The backlights come on, but no visible picture, and no sound. First instinct told me main board. I've changed it, no difference. I got a good deal on a power board, still no difference. The screen lights up dark gray, and does change a bit with the buttons on the remote. I've been reading here on the site, and anywhere else I can for tips on this, but not finding much.
