Having owned a couple of Samsung TVs and done quite a bit of research, I'd say LG is the brand that I'd go for when I buy my next TV. My Samsung TV's infrared remote signal receiver broke after ~1.5 years. I had to call several times to arrange a repair person to come to my house. Guess what, the contractor they hired to send the repair person has poor organization skills--they double-booked me for appointments and yet failed to send anyone to my house. After calling Samsung customer support and chatting with their reps many times, they finally said they'll refund me the money, which I naively agreed to (they had me sign an online PDF or something). Guess what, when I bought that TV, it was ~$350 (including tax) and they issued ~$328 for me even though my Costco receipt clearly shows that it was ~$328 total (they only issued refund of the base TV price--not including the tax and such). The rep was smart in not telling me that I could have told them that I want another TV as replacement, but I was naive and after calling and speaking with them for so many times, I just wanted this ordeal to be over. The whole ordeal took ~2 months and after that, I swear myself to never buy Samsung product again.

I look into other TV brands and either they have very suspicious privacy practices (Roku and TCL) or they are made with items sourced in just one country (e.g., TCL and Hisense, which are both based in China).

That leaves me with either Sony (too pricey) or LG and LG seems like the most non-smart TV with sources all over the world (Vietnam and sometimes Mexico), as opposed to mostly from one country.
