Re: Vizio XVT3D554SV Flashing logo, intermittent backlight, no sound or image

I also am having issues with my XVT3D554SV. A few days ago we came home and began watch tv. Suddenly our sound went out. We worked on it for hours. Hard resets, unplugging EVERYTHING, we even left it powered down and completely unhooked from everything for an entire day. Still no sound. The picture however is still flawless. I tried every input on the tv and could not get sound through any of it. I checked through the menu to make sure all the settings were right, turned off and on TruVolumn and so forth,...
