My tv has been on a good 10 hours a day since April and there's no burn in but I don't have ATT which I've seen defaults to some screen if tv is alone for a while.
I bought a BOX of caramel russell stover pumkins at target after halloween and I've been practically in a sugar coma the last 2 days. I'm good for a while thanks. If this lasts much longer will have to go make crack....errr..coffee
