I have the 60XBR2 and had 6820 hours on my original bulb before I replaced it. The bulb was still working, but I felt the picture was starting to look dark. I installed the new bulb that came with the television and all was well. Two weeks pass and when I turn on my television, the red led "lamp" light flashes and I have no picture or sound. I only had about 100 hours on the new bulb, but it was dead. I re-installed the old bulb and all is well again, except for the slightly darker picture. I called Sony about the bulb problem and they wouldn't do sh*t about it (hard to believe, I know). I'm writing a letter to the corporate office in Fort Myers, Florida regarding this situation. Granted, the bulb is technically 2 years old, but it was never removed from the original box and it was stored in my closet. I feel that it's no different than me ordering a new bulb from Sony, them pulling one off the shelf and shipping it to me. I feel they should cover it or at least give me a discount on a new bulb.
