TV model: LN40D550. Blu Ray player connected via HDMI.
This usually happens during the opening credits when there's no text displayed and there's only a black picture or whenever a scene in a movie fades completely to black. The screen will start flickering as if alternating between off and on mode as if it does not detect a signal, when in reality it's just a black screen present in the movie. It looks like some kind of energy saving feature anf whatnot. Any help? thanks in advance.
