I also have a blue streak on my sony kdfe50a10 purchased in 2006 and bulb replaced 2011. Based on what has been said before in this thread I did not see where I could lose trying this. I sent an email to email@example.com and requested information about a replacement. I sent the email on 5-13-2013 at 3:38 PM. I received a reply on 5-13-2013 at 3:46 PM.
"I apologize however due to the age of the KDFE50A10, this model is no longer included in any replacement program. However, because we appreciate you as a customer and since retaining you as a customer is very important, we can offer a replacement option as a gesture of goodwill.
OFFER: KDL50EX645 for $550.00 + any applicable taxes."
That is an exact quote. So, as of 5-13-2013, there is still a chance to get a new tv for a substantial discount. The OFFER is for a TV that has been discontinued and did not get very good reviews from the pros (CNET and PC WORLD), although most regular people on a budget liked it. Best sale price out there now is about $998.00. Credit card is not to be charged until tv ships, and I check this daily. It has not been charged the $550.00 yet. Since shipping is free, all I have to give up is my right to sue Sony over my current tv (which I get to keep). Two things strike me as weird. 1. They must know something really bad if the are willing to settle this in this manner, and 2. I note they are sending me a tv that is no longer being sold once a store is out of stock. I sent in all requirements on 5-15-2013 by certified/return receipt mail, and today is only 5-16-2013. If I do NOT get my tv, I will be back for an update, but so far I am impressed with the service. If there are no more entries, assume all went well. No news is good news. Have you ever noticed there is never any roadkill within 1 mile of a fast food joint?
