I bought the JVC in early October, 2007. It failed in the last week of September, 2008 (almost 1 year.) The replacement engine failed in late February of this year (2 years, 5 months.) I always powered it down as it should be, but there may have been a power outage somewhere in there. It was connected to am APC Line Conditioner/ Surge Protector the entire time. From what I was told by the service tech, there is a filter that warps due to heat, causing the discoloration. I run the TV almost every day, probably for 3-4 hours daily during the week, and anywhere from 3-10 hours on a weekend day. Pretty heavy use, I guess. The TV is on a stand, not in a cabinet, and is very well ventilated.
About 18 months ago, I bought a backup lamp, just in case. I put in the new bulb immediately, since it was in warranty and the other wasn't. About a month ago I got the first alert on the TV that the bulb should be replaced. I don't believe I reset the timer when I put the new bulb in, but I'm not positive.
