It is a common firmware issue. You need to call Vizio for help.

"I called Vizio and after scanning the receipt and talking to support they told me there is a firmware update. They sent me, at no cost with prepaid return shipping, a black box with an RGB and USB hookup. I connected to TV and pressed a RESET button (following instructions). Then power it on. The next step was to disconnect this box from the TV. Power it off. Then insert a USB flash drive they sent. Turn on TV and update the firmware. This has fixed the TV. It now works perfectly! I am left to wonder how many recently out of warranty TVs have been scrapped because the repair service wants $185 to fix and most people will not call the company because the TV is out of warranty. Most people will not pay repairs considering the TV is less than $300. Hopefully, this post will help others with the same problem. VIZIO fixed!"

That is most likely the power supply in the TV. It could be the processor board (main board) CPU but that is less likely.
