Need help with smart tv that can no longer access internet

[Beatlelvr]

The family has decided 99 yr old mom needs more care than I and fulltime caregiver can give her at home. She has been bedridden since she got covid 6 months ago. So we are moving her to a facility owned by a family friend. I want to move the tv I have now to her room. Problem is it's a Samsung that lost its ability to connect to internet. (AT&T did a diagnostic test and its the tv, not the connection.)
I called AT &T about getting service at new location. I don't want Direct TV, so they said the tv can be used with a Roku or something similar and must accept apps. I understand Roku can work without internet. But, can the "unsmart" tv accept apps? I don't think so. When I try the Smart Hub thing it won't do anything.
Any suggestions?
I suppose I could go ahead with Direct tv, I just don't like the dish thing.
Thanks for any advice.

1. We had a Samsung

That did the same thing. Had to
replace it

2. I don't know how a Roku could work without an internet connection

Which the home should have. I think your tv is now a dumb tv. But it may work with a Roku or Fire and an internet connection, but I doubt it. Otherwise you can get a new tv, which are really cheap now. If you get another smart tv you won't need a Roku.

3. Had a Samsung a few years ago. Would this help? We had to reset a few times, I recall.

4. Thanks so much!

What I did was go to Menu, then Smart Hub, then did a "set up". It worked! Yea!!
I thought I had gone through everything, but your suggestion helped.
