I'm new to this site and not certain that I am posting this correctly. If it needs to be moved to another forum, etc. please feel free. I have new TV ...iSymphony ... made by ESA/Samsung. I can program all of the basic functions on the RC65RX using any of eight different codes ... power, volume, etc. However, the receiver/TV dual ON/OFF button do not work for the TV. I can move the slider to TV and the PWR button will work, but move it back to DirecTV and the ON/OFF power buttons will not work for the TV (works fine for the receiver). I would think that if the "PWR" button can be programmed to work ... the ON/OFF buttons should also work ...they've got to be the same circuitry! Thanks for your help.
