Vizio sv471xvt black screen

SOURCE: Vizio 42", have picture for about 5 mins then screen goes black.

also check the power cord wire coming from the back of the tv is loose from the tv side or perfect.

SOURCE: I CAN TURN THE POWER ON. THE SCREEN STAYS BLACK.

This TV has 2 main circuit boards (2 LCD backlight controlers): the Power Supply board may have fried the video board on it's way out ...
You can either arange to have the TV replaced under warenty if not have it serviced. In any case best of luck with Vizio support line.

Everyone bought this TV because it was so cheap... now we find out why: Vizio cuts corners on everything from engineering to support!! All brands are not created equal. Sometimes you get what you pay for.
