A:Answer There is a setting to automatically turn off after a certain amount of time for folks who watch TV in bed. Unplug TV for a few minutes, and then plug into a wall outlet rather than a surge protector to test. Check surge protector if you had it plugged into one. If TV turns on using the wall outlet, then check if setting to automatically turn off got set by mistake, or surge protector got tripped. Otherwise, if none of these suggetions work, check the SONY BRAVIA on-line help for other suggestions.
