I have all but decided to buy a Sony 34" XBR910. Should I buy the 5-yr extended warranty with it? It comes with a 2 yr labor and parts, so I only get 3 years with the extended. Although there is some question as to whether the manufacturer's warranty includes in-home service or not. Sales rep says carry-in only. Sony web site says 90 days in home, carry in after that, but only up to a year. Sony on-line live support says carry-in and/or ship. I don't think so for shipping at 300+ lbs. Not that I want to, but I have capability of carry-in to local authorized Sony repair. Real question is do I need the warranty? Are these CRT sets prone to potential problems to make the cost worthwhile?
