Hi have been using my denon precision audio component / av surround reviver for a little over a year. i was watching a movie when it just shut off. the standby light came on, i tried to shut it off the on again but it stayed on i took the top cover off and checked if it had over heated, it was fine i have good ventilation nothing was warm. i unplugged it and waited about 1 minute turned it back on and there was no display only the stand by light was on. how do i fix it !
