"It's referred to as 'flashlighting'. It's a common problem in LCD/led as the driving factor is lighting pushed through pixels to create the picture. What you are seeing is a spot where the lighting is passing through unscathed or overpowering around the edges since this is an edge lit tv.
Some TVs are worse than others even if they are the same model, size and even batch.
This can be caused by many reasons... You have 2 options, return and/or exchange it at your local store if still in that window. Or you can call the tv manufacturer to see if it is out of their allowable tolerance levels.
Remember some flashlighting is still within their specs so even though you may not be happy with it the manufacturer may not fix it.
Many people find some relief by turning brightness down, contrast down and some TVs allow you to adjust back light levels. If this one does then make sure it is not on high.
For more info on this I would go to hidefjunkies.com as it has tons of great info."...Also,"take it off Dynamic mode is the first step. Then put it on something like Standard or Movie. This will not fix it permanently, but will give you a better experience." (I hope this answers your question...if it was ME,I would take th darn thing back,if still within warranty period.)

OK Service tech came out last night (7pm) and repalces the main board and updated firmware to the latest. he said the red/green snow is a fairly common problem with the early units (mine was a july 2006 build). Picture is fine now but we will see how long the fix lasts. Main board was definitely the issue, firmware upgrade was prob just because they could.
Keep in mind this unit was OUT of warranty. I find it refreshing that Vizio took responsibility and set up a service ticket for a 16 month old unit. Not that they shouldn't last a lot longer but they could have just said tough luck.

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs. After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support. They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables. So far, so good.

It sounds your panel is going bad. If you call deferent shop you might find someone that has refurbish panels, or half price panels,call around. I would try that first. Then only if I have too, then buy ba new TV.

Check for bad capacitors in power supply, check voltages coming out of the power supply, if voltages are good, bad main board.. Vizio's are notorious for bad main boards.
