As we all know there appears to be no discrete codes for on off. I reading the Onkyo manual I came across the sleep comand. Seams that if you push it once it puts 90 minutes on the timer. each time you push the button it subtracts 10 mintes untill 10 minutes are left then it disables the sleep command. Can anyone think of a way to use this feature to figura out a work around for a discete off. Just a thought.
