So I just received and set up my Vizio 65" LED.. and it worked perfect for the weekend. Now I've got green contrast on the screen (obvious in the menu; so not cable or signal related). This is a sign of the main board going out. Anyone else seen this? Should I let it rest a day and try again? Should I be contacting Woot about a return? My only real concern is how the hell you ship back a freaking giant ass TV??
