Query: Wonderful until the backilghts went out after 2 years

Seriously, this was a wonderful tv but it didn't last.After 2 years one of the fluorescent backlights has a flickering problem.Sony has basically said that I will have to pay almost half of my original purchase.There has been a grand drop in quality over at Sony. Pretty much every piece of electronics I have purchased from then in the last 3 years had been poorly designed and overly expensive. I used to justify it because my previous Sony purchases lasted forever. This is just not true anymore. I have been a loyal Sony customer for the past decade. No more.
