I don't know, I still hear many problems with dead pixels and such in the forums. I for one have an entire line of dead pixels 4" up from the bottom on my Samsung LN-T4069F and it happened just shy of the 1 yr factory warranty and luckily I did purchase the extended warranty, so I am just waiting till it nears the end of its life(the extended warranty period) before having it repaired/replaced.
