Are you a decent do it yourselfer? It sounds like it is the capacitors. What happens is they get hot and expand (the top of the Capacitor). The top will be dome shaped and it will look like the top is splitting open. You can buy (about $1.50 ea.) the capacitors at your local electronics store (not Radio Shack they usually don't have a high enough amp).
You will need to take the back off and look at all of the capacitors to see which ones are bad. Usually it will be 2 or 3 of the larger ones but there could be more. Next you will need a soldering iron with a fine tip and some wicking material. How could are you at soldering and de-soldering? before I go on.
If you let me know the model # of your set I can be a little more detailed also.

The tv is having a problems with the board called T-Con board it is dying and the problems.That why the tv is not sustancening the tv pictures for those coded pictures pixels by the T-Con board to stay on to the tv LCD screen panel.This tv problems only causes by the tv T-Con board it is dying only if the tv problems came on to the tv by itself only.If these problems causes by u or an object by outer forces by hitting to the tv LCD screen panel itself.Now the tv LCD screen panel itself it is dying and the causes.Than the tv it is not repairable,tv now only can it to do a replacement of the tv whole LCD screen panel itself only.Not practical because the tv LCD screen panel are 90% important to the tv and the cost of the tv.If u replacing the tv LCD screen panel itself will cost the same as a new tv.The tv is under a year old,why don't u just call Vizio corp. and take ur tv warrenty repair.
