Nanocell shutting off on its own?

Hi. :) So I have a 65 inch NanoCell that I got baci in 2024, and its been working great. However, I've noticed in the past year or so that, when Im playing videogames on it, it will sometimed turn off on its own. It doesnt lose power; when it turns off, the red light on the bottom of the TV goes on to show its powered off. I checked for software updates, but my TV is on the latest version. Is this a known issue with these TVs?
