Hi! For some reason, the remote suddenly stopped working on my Vizio model E601i-A3E. Also the manual buttons on the side seem non-functioning. (Might be coincidental, but I noticed it shortly after we had a power outage in the neighborhood for about 15 minutes.) The TV was ON and it came back on after the power came back on. I can control channels etc, with the cable box remote, but can't shut the TV off or use volume control or anything with the supplied TV remote. The set is less than 2 months old. Please help!!
