Question about Vizio Televison & Video
Your tv has it's lcd screen backlit by some special neon tubes, called CCFL tubes. In your case the connection to one of them is bad so it's getting its power only when the heat from the other tubes and components expands the metal from the pins in the connectors.
To fix it you will have to take the back cover of the tv off , take off the tube shrouds and reset the tube in its connectors - eventually pinch them a little with pliers before reinserting it.
