Nothing really important to say. I am close to 9000 hours on my 92840. The extended warranty is good till around Christmas this year (2015). I hope the set hangs in there another 12 months or so. No maintenance other than lamps so far.
No affordable jumbo displays out there yet. The 2015 Vizio M 80 inch is $4K but that is not big enough and all the ULTA HD stuff spec wise is still in flux. Hoping the old monster keep going long enough till there is a viable replacement on the market. I will be calling Mits for yet another lamp before the NFL Regular Season starts again. Good luck to all of us with the 2011 sets.
