Just purchased this Samsung TV less than a week ago. Today it shut off and eventually turned back on. This was the 1st time it happened but I have read numerous posts on this forum where this problem occurs on other models as well. In the event this happens again, is there a fix? Fortunately it is still under warranty. Suggestions welcomed.
