a couple of years ago we got a good deal on a "reconditioned" RCA TV at a local appliance store. it's worked great until recently ... now, every once in a while, it just turns itself off!
it's disconcerting when it happens during a show or game, but usually it blinks out when the show is transitioning to commercial or from commercial to show. it may not happen for hours, then happen every 20 minutes or so for the rest of the night.
so .... has the Bermuda Triangle shifted to the northwest? is our house built on an ancient burial mound? has some electronic hoodoo infected the TV to the point it needs a tinfoil hat? or is there a logical explanation?
