Spouse has limited central vision. Seeking good quality 55"+ HDTV with best life expectancy. Your suggestions? VT30 seems optimal.

which means the screen will be about half as bright. This half life is about 80,000 hours. You can do the math on how many years this is.
If you look 2 hours a day, that's 40.000 days = 110 years. Which shows that the half life of the screen isn't the limiting factor for the economical and technical life time of the whole device.

To get into life span discussions we have to nail down the terms first. We have MTBF, MTTF and of course MTTR.
http://www.jvcpro.eu/jpe/video/product.3171.140.html is just one example of a 50,000 MTBF.
If you look up want MTBF is, it means, on average you will see a failure by about 50,000 hours. Or about 6 years.
The MTTF is always less than that so using this as one number you expect a failure from day 1 to 6 years out.
No maker appears to be making anything to last longer than 5 years.
My advice is to to not overspend on these things.
