My 55st50 is turning off then on randomly when there's a fluctuation in the signal, like between commercials or when switching picture modes, especially when trying to switch to game mode. Some times it happens when I exit out of a recording on my DVR. I've tried plugging the tv into different outlets and I've even reset the tv by doing the System Check power down thing. Anybody got any ideas?
