The best and most correct option for such TVs will be the IPTV set-top box on Android!!! Everything else is just makeshift solutions!!!
Our TeamPlay player can be installed using MSX according to the instructions
The OTT-play FOSS player is for LG, Samsung, and other non-Android TVs
https://ottp.eu.org/www/install/ (Player installation, three ways)
Follow the instructions in 5.5 Setting up ott-play player..
The Kodi media player, follow the instructions in 5.7 Setting up Kodi multimedia player
The Smart IPTV (SIPTV) player
Attention, the player is paid, but you can test it for free for 7 days!
Install the player on your TV
LG
Samsung
Upload the playlist to the player https://siptv.app/mylist/index.html
a) in the MAC field, enter the MAC address of your TV;
b) the "snake" to the right of the MAC field changes the playlist upload method, either you download the playlist and specify (choose) the path to it, or specify the link (URL) to the playlist and the device itself pulls the necessary playlist from our resource; the link to the playlist can be found in the personal account Playlists->Links choose the SmartIPTV playlist and click the Copy button, the link to the playlist for this player looks like https://tv.team/pl/13/*******/playlist.m3u8 (instead of asterisks is your unique access code (token)); we recommend the second method of playlist upload, because when changes are made to the channel list, you will not need to download the playlist again;
c) in the EPG field enter the link http://epg.team/tvteam.xml
Reload the player and watch TV.
You don't need to specify the EPG country; if you want to, you can choose ExUSSR for Russia.

The ott-play by Alex (not for Russia and Belarus) player, ATTENTION!!! Ott-play by Alex blocks Russian channels and servers, if you need these channels, use the OTT-play FOSS player (above).
LG Samsung Toshiba, Panasonic, Sony, Philips, Hisense, Skyworth, TCL, Sharp, Haier...
Set up the player according to the instructions 5.5 Setting up ott-play player.
M3U IPTV player (only for Samsung Tizen and LG WebOS)
https://m3u-ip.tv/
To set up the M3U IPTV player, use the playlist for Televizo.
It seems that the archive on the M3U IPTV player only works on the Premium version of the player, which costs 1400 rubles.
ATTENTION! due to the update of the donor app RedBull, on many Samsung TVs, the ott-play (FOSS and DRM) player, installed this way, stopped loading. For this reason, it is better to install these players on Samsung TVs through a widget (using a computer/laptop). Download an archive of either player to your computer, unpack it, run the application (file with exe extension), and follow the instructions that appear on the screen:

https://forum.tv.team/files/DRM-play/DrmPlayInstallTizen.zip
Additions and clarifications to the instructions:
1) for more information on how to access the developer menu, you can check the internet using a search engine;
2) the computer and the TV must be on the same local network, i.e., connected to the internet in the same way - both via a cable or both via Wi-Fi;
3) press the buttons in this order 1-OK-2-OK-3-OK-4-OK-5-OK, i.e., after selecting a digital button, press OK, and the keys must be pressed quickly, without pauses.
