Hi. What would cause my stereo to turn itself on by itself?...It has done this once or twice a month since I have gotten it 3 or so years ago. But just recently( past few months)it has been turning on several times a week at different times of the day. Don't tell me its haunted?! Thank you. Oh which off button is really off ? The STANDBY ON or ECO POWER. In case I'm not shutting it off with the right button. Thank you, Stephanie
