the usage only 3000 hours!
and the picture still look as good as a new set and the black level still at 0.006 as measure using Calman, same as 2 years back....so no floating black....

but...darn, when is this thing gonna break so that I could have an excuse to change to a 1080 FullHD 65" set.....

look like I am gonna stuck with a 720p set for quite sometime..... frown
