Solution is to get it fixed (hopefully under warranty).

I have the same issue after owning the Vizio 42" LCD for just 5 months. They are coming to replace the part this week. I will also be purchasing the extended warranty as well, to avoid this problem in the future.

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:

1. Grab a flashlight.
   
2. Turn on the TV.
3. Shine the flashlight onto the screen.
4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
5. Replace which ever is the culprit.

Before you go to any more trouble troubleshooting potential hardware and/or connection issues, look at this page of reviews on Dell's site, taking special care to read 'Review 8' by an owner named 'Milwsport'.
