Normally no but for big ticket priced tv's yes.
My story. I bought the top of the line Sony XBR 53" five years ago and got a discount on the extended warranty. (Negotiate the price down for the max number of years is my policy.) I paid the three year price for five years of coverage. One month before the warrenty expired, the picuture tubes died. It took the service people almost three months for various parts to come in and be installed before it was determined "unable to restore to original specs". "Replacement" under the coverage was going to get me the current equivalent large screen rear projection Sony but it was almost half the price of what I originally paid. Instead of accepting the new mid-line Sony, I took the credit against a 65" Mitsubishi HDTV.
TV projection tubes have shorter lives than before. They'll give out about five years so if you get coverage pay for the five year coverage and negotiate the price. Any coverage under that time is playing into the game of paying for a service you'll likely not use.
