I have searched but cannot even find a similar request across the web.

My R-Box (Amoled processor) has a discrete Power On command that is the same as my LG TV's Left Direction key (discovered by accident). This leads me to believe there is also a discrete Power Off command. I have entered all the common discrete off commands into my OFA but none work.

Any tips or suggestions of finding the code? It would make my Harmony setup a lot smoother. TIA.
