I've had my new panasonic st50 for about 3 days now, and have about 18 hours of use of it so far. It's working great and the picture is amazing. Two times now there were sudden occurrence where the TV would shut off by itself and then two seconds later turn back on. Nothing seems out of the ordinary, it's not overheating or anything. Like I said, it's not happening a lot (not yet anyway) but it has happened twice while just watching blu rays. Any thoughts?
