When you say a free replacement, do you mean a new bulb or TV?
Sony gave me around $700 credit towards a new Sony LCD (which I've already purchased), so I would guess the matter is now settled.
Even though I give Sony credit for at least offering something, I really do think my full purchase price should have been refunded. This wasn't a defect that just effected a small amount of TV's, from the looks of it, they all seem to eventually get there, it's just a matter of time. $3,000 is a lot of money to now throw in the garbage, and while $700 was nice, I would much rather have bought a high-end TV that wasn't disposable. This wasn't a budget "Wal-Mart" Sony TV, this was their flagship model.
I have a family member that had a Sony LCD projection TV, and it also had significant issues, and Sony gave credit towards a new TV. Again though, it wasn't nearly close to what the original purchase price was.
I used to be a big Sony fan, but they went from being the gold standard to trying to sell low-cost to the masses, and their quality has clearly suffered. I have a 15 year old Sony CRT that's still kicking like it's brand new without a single issue. Sony is just not the same company anymore, and I now avoid them.
