That tells me you're not entering the codes correctly. Sounds like you actually need 5 digit codes. Nothing happens on the first try, because it expects two more digits. On the second try it gets more digits, but they're invalid. Finally the last digit performs it's built-in function.
Try it like this:
With your yamaha already on,
Press AUX (you only have to do this once)
Quickly tap "Setup 0 0 2 4 6" to turn it off
Try some of the other codes using the same method of a quick tap of setup followed by 0 0 then the 3 digit code. This sequence of button presses has to take place quickly, about one key every half second. No need to press AUX again, just setup followed by the code. Don't hold down setup like you would to change the device code, just tap it.
It's possible you aren't pressing setup hard enough, especially if it's recessed.
It's also possible that it expects 3 digit codes, but you are entering them too slowly. If the 5 digit method fails, try 3 digits again, but faster.
If none of those things work, you're out of luck as far as this remote goes, because those are the only discrete power codes for yamaha that exist, AFAIK
