First of all must thank all of you for your collective knowledge. Been lurking since early December when I first started experiencing the green "blob". Thanks to the information I gained here, just finished the "Sony Renewal Process", with a quite satisfactory result.
Details in a nutshell: Orig purch Dec 2006, been through 4 bulbs, the last of which seemed to kick off the problem, did my research here & elsewhere, began the process & was offered a KDL55hx850 for $970 + tax. Best price I could find online was over twice that amount. To be credited over $1000 for a tv over 6 years old was more than fair in my opinion.
I've had the unit for for less than a week now, but so far I am very happy. For that matter, so is my nephew who just received a 60" tv for his college dorm to watch the Patriots win this weekend to go to another Super Bowl (even if everything looks a little green!). Now i just have to figure out why I'm going away to ski country this long w/end to watch the game on a smallish SD tv??????
