With those Vizios, the EEPROM gets corrupted and the set tries to operate in many modes at once. Replacing the System board with the eeprom on it will fix it, as will swapping in a blank eeprom.
Just curious, is your set a 55" set, with all the feature labels still attached to the front? A neighbor just tossed one about a month or so ago.....he had swapped the power supply board, but didn't want to go any further. Too embarrassed to have me take a look at it, so he let it go...
