I call it collusion tactics. Nobody's responsible for anything. It's the constant theme. (The person's thread you replied to had to divine the Roku model number from thin air. There's no cross reference -- even though customers repeatedly demonstrate a need for it. That's how obfuscated the boundaries are. There's different model numbers depending on who you talk to.).
If I were you, I'd try the pinhole factory reset on the back of the tv. Unplug, press the power button for a minute to drain any capacitive energy. Then hold the pinhole reset button while plugging the tv in. Continue holding it 15-20 seconds until the front light flashes or dims (? This is a little unclear to me how the different brands might work). If you end up in the setup screen, you can tell it you'll connect to internet later. See if the problem exists when watching antenna tv or streaming through HDMI port.
Another thing you could try is the so-called cache clean:
Hit HOME 5 times.
FAST FORWARD twice. (Clears cache & tv reboots itself. Be patient. It takes 2-3 minutes for the tv to go black, and come back on)
If the tv is recognizing the remote (long enough to press those keys), it might fix it. It fixes some problems that factory reset doesn't.
These tvs have a modular board assembly. You can find videos about how to replace boards to fix different problems. That might be your only option if the above doesn't work.
"People are often amazed at how much we’ve done with the number of engineers we’ve got." (Roku CEO Anthony Wood, Austin Statesman, Oct 4, 2019). "Amazed" is one way of putting it.
