Emerson 40" is pretty good.

Yeah, my have similar issues with my Grandma. Problem is she won't ask anyone for advice, she'll go out, buy something way more expensive than she needs with more features and more confusing interfaces than she can handle. Get frustrated with it and not use it, thinks she needs something else, repeat ad nauseam. It's her money, she can do what she wants, but every time she gets something I have to teach her how to use it for her to just forget what I say and end up getting something else. Like Grandma, please let me just buy you an old TV and stereo on eBay that you can actually use and just be happy with it. Getting her to figure out streaming services (by her request) is impossible. She really just needs a classic cd player
