re: In market for new budget TV. Looking for advice.

I bought my inlaws a TCL 6 series - google tv for Christmas and we were very impressed by it. I bought a smaller vizio on black Friday 2020 and it is having issues. When playing anything on the TV hardware itself it flickers on white parts of the screen, the UI freezes indefinitely and I have to unplug and plug back in. I've swapped to an nvidia shield on that tv instead of the vizio ui and it only recognizes the input about half the time (a hard reset corrects it). Additionally the vizio has a one year warranty from most retailers except sams and Costco. Those two retailers offer a three year warranty.
