As discussed in this thread https://community.verizon.com/t5/TV/Problem-with-Fios-Voice-Remote-Powering-Off-TV/m-p/1688731#M103858 I just got new equipment. My 4100ipc voice remote does not retain the code. If I manually enter the code via the TV model, the power off button works then, but then it stops, maybe 30 minutes later.
