Not sure on Sony televisions, but here is what I found out about Mitsubishi:
Mitsubishi's come with a 1 year factory warranty.
Up until the warranty expires, you can purchase a 3 year extended warranty from them. Before that 3 year warranty expires, you could renew that warranty, and none of the years overlap. You can have up to 7 years warranty on the unit.
I checked with Fry's Electronics, where I intend to purchase mine, and the largest they offer is a 5 year warranty.
Needless to say, I will prchasing my extended warranty from a different place from where I bought the unit.
