I swear I updated my set over the weekend when it prompted a software update was available. My wife was home all day with our sick little one, never noticed an issue while watching the TV during the day. I came down after showering this evening, flipped it on.. and there's terrible flickering/shuddering on any overlays like watching hockey or a news channel. I was able to resolve by flipping to game mode on the picture settings... but wtf? Ive only had this set since October...
