@Psyrog , if your tv isn't responding to the remote, you can view the front of your remote through a cell phone camera to see if the IR is actually luminating. (For some reason you can see that through a phone's camera.).
That would clarify if the remote's not working, or the tv's sensor failed.
Or, are you saying you have (or had) a wifi problem? Are you stuck on a setup-language screen? How/why did you get there?
There is a factory-reset pinhole button on the back of the tv. Your tv's manual will explain how to use it (google your tv model to find the manual). I'm sure there are videos showing how to do it, probably applicable to all models.
"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.
