There was a little storm last night and my power went out suddenly for several hours... so when I awoke this morning to watch the tube, I was most unpleasantly suprised that the guide was taking several seconds to show up when I pressed the remote, and when it did show up, the scrolling/response time was laggy, not to mention very glitchy. As a matter of fact, everything I pressed was lagging! I figured it might be the remote so I tried changing channels through the reciever, alas, that too was laggy. Could the sudden power outage have corrupted something internally or maybe a surge when the power came back on could've fried something? I tried turning it off for a few minutes, unplugging it, everything, but no luck. What should I do?
