Iggy, that's what has me puzzled. No clocks were blinking and my micorwave oven is incredibly sensitive to power outages and its PF (power failure) indicator was not on. The only thing that indicated a power loss was the tv's message. Both the tv and the 950 are connected to different surge protectors. Microprocessors are mysterious at times, but two components at the same time? Maybe it's witchcraft. So far the 950 has retained its setting for the past three days, so it's hard to rule anything out.
