Hi, I hope this is the right sub. I have a Phillips 55PUS7303 that runs Android TV, built in.

I mostly use the built in chromecast functionality, and it's great and stable, but I have some small issues, that could be related.

1. I can set the name of the TV in android TV's settings. But after it's been off for a short while (standby button on the remote), the name resets to the default. It's an ugly name and I'd like to keep it as "Living Room".

2. The built in chromecast is visible on my network for about 3 minutes on my network. After than, it seems to disappear, I'm guessing the TV is going into a deeper sleep than standby, and turning off wifi or something. I like the wake functionality of the chromecast, so I'd like it to always be available.

3. I really like the chromecast backdrops, and I can enable them on the TV, but they'll kick in even when I'm watching something on the HDMI port, I had to disable it because it really gets in the way of playing games when the backdrop suddenly starts showing.

I'm guessing at least points 1 and 2 are due to the TV shutting off, and not having a built-in battery, so losing settings. But I couldn't find an option to stop it doing that. Is there anyone with a similar model or similar issues who can help?

Thanks

EDIT

I think I've fixed points 1 and 2! There's a setting in wifi called "Enable wake on wifi", and when you check that, another setting called "Wake TV with chromecast". I set those, set my name back to Living Room, and so far, it seems not to have gone away.

I'd never thought to look in there, because firstly, who puts standby options in wifi? And secondly, I don't actually use Wifi, I use wired ethernet because I stream 4k content

EDIT2

So my apparent fix has't worked. I've gone through every setting on my TV and I can't see anything that'll be causing this.
