You can find example after example where that many years and it's OOW (out of warranty.) No TV maker is offering 4 or more year warranties. It's a sure sign that these are not made to last a decade.

-> There are some known issues that makers do cover such as that model that escaped with an uncut jumper but that's the exception to the story.

If you find a maker that will deliver on a 10 year set, let us know.
