Remotes

[Angelo81]

had to do a factory reset cause  Direct TV (cable) stopped working, all other features worked just fine. So I did the factory reset and my cable worked again, had to turn off store mode to disable an advertising pop up, and now the sleep timer is off, I open settings > system >  there's no time or power option

RokuTVs have sleep timers, Roku devices do not.

If you provide some more details like the model number of your Roku (TV or device) can verify where the setting may be located if following the instructions in the above Roku Support article does not help.
