After much hunting, I've found a remote code that will work...to a point. I am now able to turn off and on the TV. Unable to do anything else though, as the TV and Optik buttons are the only two that work. What am I missing?
1724 gets the slimeline 2 to turn off & on and volume then use roku remote options (star on the roku remote) then systems then power then power on then select your cable box and it will come on when you power up with the slimeline worked for me!
