A strange occurance today.

A strange occurance today. We have two working TVs in this house. Neither is used very often nor very long at a time. The main TV is a 19 inch set in the Den. It gets watched for maybe an hour a day, usually in the late evening. The other set is a small digital (8") that we have on the mantle in the kitchen. This TV has to be physically turned on because the remote will not turn it on or off. We don't use the remote because this set is on one channel and it stays on that channel.  We generally only have it on for news and/or weather. We hadn't used this set for well over a week. At about 10 am today the set turned itself on much to everyones surprise and then about 15 minutes later it turned itself off. That was it. nobody even near it. The useless remote is in a drawer of the kitchen table. This set has never done that before. It worried my wife because the only other time such a thing occured was probably about 20 or so years ago. At that time we had a manual TV set that  required a viewer to walk over and manually turn it on and manually change the stations. That time, at approx 10 pm as we were watching a show, this TV changed stations. Something that required manually twisting a knob on the set to do. Noone was closer than 10 ft from the set. My wife and I both saw it happen. I immediately got up, walked over to the set, and changed the channel back to our program. The next day, we were informed that our next door neighbor, who was in the hospital, had passed away at approx 10pm. Coincidence ?  That TV set never misbehaved in such a fashion again. So a TV set turning its self on and then off; has her a little worried. Hopefully for no good reason.
