I hope you have better luck than me!
I bought JVC's top of the line 36" HDTV-compatible tube I'Art which was selling out at the Good Guys for half of retail. The performance of this model compares favorably to the Sony. I finally found one factory-sealed and drove an hour to get it. It lasted all of 2-1/2 months before going 'poof'.
Any TV over 27" they state an in-home warranty repair, but guess what? I live in the country and none of the warranty centers were willing to drive out here to fix it. So... load the 200lb TV back up and bring it in for repair. 3 weeks later I just got it back and it looks beautiful again... for now.
JVC warranty is 1 year p&l, 2 years on the tube. I believe Sony is worse at 90 days labor (for a $2500 TV?). I declined the extended warranty because there are no moving parts and TV's last forever... don't they? Well they used to... I pulled my 20 year old RCA TV (the first table-top model) back into service while my 2002 model was being repaired. The RCA never has been.
So... a pet-peeve of mine is that it is my impression that the TV industry is so cut-throat even in their top of the line models that inferior components are used throughout to pinch the pennies out. Sure wish you could pay an extra hundred or two for top shelf components... I'd do it in a heartbeat. Sort-of Sony's philosophy with their ES line. I was naive to think I may have purchased a 10-year (or more) TV. That kind of thinking is a pipedream anymore.
Good luck! The big tubes are awesome when you don't need to lift'em!
