I tried this same technique with my SA-XR55. Only the last code, 1200, would work for Mute and Vol. None of the codes would work for power.

Give the Technics codes a try. In fact code 1126.

Well, that code worked for mute and volume, but not for the power switch. I'll try more Technics codes.

Bingo. I tried a different one of the Technics codes and that worked. Thanks for all the tips!
