Just this possibility, makes some sort of a third party, warranty even more compelling. I know a little about this subject, since I bought an Olevia 265T FHD in June of 2008, and Olevia went under in July of 2008. That event was NOT unexpected, and I had already purchased a Sam's Club 4 year add on warranty, which will not expire until June, 2013.
The problem with Olevia now is just getting parts. If you can scrounge the parts, the sets can be repaired. There are no official channels for any parts, and even a minor problem (such as non-functional audio) leads to a full $ set unrepairable payout on the warranty claim! Then they let you keep the set, and if you are able to find parts, (or alternatively use your HT setup for sound).
All that said, I have NEVER had a claim under any extended warranty. So, whatever money you or me, or anyone else spends on extending a warranty is likely to be money down the rat hole!
So, I estimate that I have a 1 in 16 chance of having a claim during the years 1.26 through 4.25 on my Sharp80. To this I add a 1 in 10 chance of Sharp failing, and it looks like a reasonable GAMBLE on my part to buy a third party extended warranty, and that is exactly what I am going to do. (Costco SquareTrade warranty).
