I have a TCL Series 4. When my TV detects there's no activity going on, say if I close my PS5/Switch, and it's just sitting on an inactive input, it ends up closing the TV after 5-10 minutes. It warns me about a minute ahead of time that it's getting ready to close with a countdown. I went into System settings and Sleep Mode is off. How do I stop it from doing this? Sometimes I just need to turn my game off for fifteen-thirty minutes and come back, and I'd just prefer if the TV stayed on while I do.
