This is not a good thing for me since I live in Central America and have limited options for repair and even less for warranty. Of course no more Panny Plasmas either even if I wanted to replace it.
You pays your quarter and you takes your ride but I was hoping the ride would last more than 10 months.

I watched the TV for 4 days with no further issues, then, last night, after about 3 hours, the TV went into what well may be demo mode as Sami Jubal had suggested. Most of the time I watch TV through my laptop connected with an HDMI cable. Once it starts the demo mode it will not stop even if I shut off and unplug the set.
It is very disruptive to our evening entertainment to say the least. I am am very fortunate in that I am renting the home of a friend and he has a Samsung Plasma, albeit 720p, but as most of our programming is streamed at 720p (maybe 720 sometimes) it does not make a huge difference.
So today I am going to start a process of elimination and leave the TV on cable for a few hours and then try the TV's media player, and finally my blu-ray player with both component and HDMI and see if it repeats the problem. I am trying to see if there is any correlation with using a computer connected to the TV through HDMI and the problem we are experiencing.
I also reset the TV to factory settings this morning and made sure I chose "Home Use" rather than "Demo Mode" at the initial setup.
Hopefully, I can narrow this problem down. We love the TV and when playing a blu-ray through HDMI it is like looking at a painting vs a photograph. We will be very disappointed if we cannot resolve this issue.
