The "off then on" problem seems to occur in many different Samsung models inculding my week-old lcd 60" 8000 series. But Samsung continues to sell this crap. If you were unfortunate enough to buy one of these gems, there's only one solution; take the damn thing back and avoid another Samsung. Fortunately for me, i'm still in the Best Buy 30-day return window. Others may find themselves in the unfortunate position of the samsung warranty which may involve a service tech not observing the problem and therefore not being repaired. Better yet, your TV could be sent out for a few weeks to a repair center. Ever get anything back from a repair center after a major repair? Fun. And you spent how much for this experience? If you're really lucky, you can experience this apparantly well-known defect while out of warranty. Good luck with that, sucker! In my opinion, Samsung sucks!
