Picture is now a series of moving bars, can't get proper picture

4 month old 47" Vizio LCD TV has gone bad. Vizio says I did not buy from authorized dealer therefore no warranty. Hope to get some help from retailer Monday.
Picture is a series of moving horizontal bars of color. Can't get anything else to happen with menu button or channel change. I am hoping for a simple fix, would like some help to narrow down. Thanks Bob

Vizio vo47L 47" LCD. No

0ne of 3 has failed:
(in order of probability):

1. Backlight inverter
2. Power Supply
3. Backlight

More specifically on #1 and #2 - capacitors either bulging, leaking, or exploded.

Please seek the expertise of an experienced TV repair technician - as they contain potentially lethal voltages that must be properly discharged before work can begin.
