I would expect a longer warranty ifI was going to spend serious money. I wouldn't be happy with any failure, nobody would, i just believe that if you are buying a product and you ask how long is this TV/car etc covered why expect longer?
Interesting logic. So if I decide to treat myself to a top of the line 100k BMW 5 series, I should accept that it is only likely to last 2 years????
You'll be doing very well to find anything other than a 1 year warranty on a TV, even on top of the range models from the premium brands.
