I've an RCA Mannequin SLD50A45RQ Tv and have used the code for RCA (321) to program my fios P265 remote and it doesn't work. I pressed the CH+ button till the remote offers up. I've also used the generic procedure for programming the distant; Ok+FIOS Television Buttons, then hold the play button until my finger is numb, and the distant finally provides up again, however still, it is not going to shut off...
