The left part of the screen of my parent's Samsung TV have seriously blackened recently, so they are thinking of buying a new TV. We probably bought this like 6 years ago maybe, but I absolutely do NOT want to buy a Samsung again (6 years is just planned obsolescence reliability + their OS didn't let me remove the bloatware in any way or shape of form)
Which brand has been the most reliable for you, and also have you been able to remove the bloatware from your TV via dev mode or with a different method?
Instead of a specific brand, I looked at what open box / display models the local places had available. I ended up with a Samsung model that was marked 70% off MSRP.
The operating system is probably not great but it's connected to a Nvidia Shield so I've never interacted with the OS beyond the initial setup.
I'd say this kind of decision has more to do with the user interface being easily navigable for your parents and what their technical proficiency is rather than trying to pick a television that might last a decade or more.
