Rca Projection Tv turns itself off

I have a RCA 52" projection tv. It has started randomly turning itself off. I have to maniually cut the set on and it goes through the setup menu like there hads been a power outage. I recently had a power outage that lasted for several days due to an ice storm. Any one know what the problem is? The TV was working fine before the storm. Could I have had a power surge damage the set? I also have two other appliances being inspected because of new odd behaviors.
