Maybe I don't use tvs the way most people do. But the most pessimistic lifetime estimates for my use case on a 30,000 hour panel is 41 years. I don't really see a television as something to pass on to my heirs so that seems like a solved problem for non-commercial use.
I've had televisions fail but it has always been a connector or capacitor that I could replace with a sautering iron and about 46 minutes of disassembly/re-assembly
