The best and correct solution for such televisions would be an IPTV set-top box on android!!! Everything else is crutches!!!
Our player TeamPlay is installed via MSX according to the instructions; while the player is in beta version, works as it is;
Player OTT-play FOSS TVs LG, Samsung and others not on Android
https://ottp.eu.org/www/install/ (player installation, three methods)
Set up the player according to the instructions 5.5 Setting up the OTT-play player.
Media player Kodi setup guide 5.7 Setting up Kodi media player
Player Smart IPTV (SIPTV)
Note, the player is paid, you can test the player for free for 7 days!
We install the player on the TV
LG
Samsung
We load the playlist into 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 loading method, either you download the playlist and indicate (choose) its path, or you indicate a link (URL) to it and the device pulls the required playlist from our resource; you can see the playlist link in your personal account Playlists->Links select 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 your unique access code (token)); we recommend the second method of loading the playlist, because you will not have to download the playlist again when changes are made to the channel list;
c) in the EPG field, enter the link http://epg.team/tvteam.xml
We reboot the player and watch TV.
You may not specify the country's EPG; if you want to specify, you can choose ExUSSR for Russia.

Player ott-play by Alex (not for Russia and Belarus), ATTENTION!!! The ott-play by Alex player 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...
Configure the player according to the instructions 5.5 Setting up the OTT-play player
Player M3U IPTV (only for Samsung Tizen and LG WebOS)
https://m3u-ip.tv/
For setting up the M3U IPTV player, use the playlist for Televizo.
It seems the archive on the M3U IPTV player only works on the Premium version of the player, which costs 1400 RUB.
WARNING! in connection with the update of the donor application RedBull on many Samsung TVs the player ott-play (FOSS and DRM) installed this way has stopped loading. For this reason, it is better to install these players on Samsung TVs via a widget (a computer/laptop is required). Download the archive of any of the players to your computer, unpack, run the application (file with exe extension) and follow the instructions that appear on the screen:

Additions and explanations to the instructions:
1) more detailed information on how to enter the developer's menu can be found on the Internet, using a search engine;
2) both the computer and the TV must be on the same local network, i.e. connected to the Internet in the same way - both by cable or both by Wi-Fi;
3) press the buttons in this order 1-OK-2-OK-3-OK-4-OK-5-OK, i.e. after selecting a numeric button you need to press OK, and the buttons should be pressed quickly, without pauses.
