- i can't turn my system off. allow me to clarify. when i turn my tv one my ps5 turns itself on even though i didn't ask it to. when i try to shut down my ps5 i also shut down my tv. my tv quickly changes modes from "ps5" to smartTV before turning off and while changing modes my ps5 turns back on....Settings > System > HDMI > these are the settings you're looking for, I believe.
