Yes, when a DLP nears the end of its life, the pictures dims. First slowly - almost imperceptible. You mess with the brightness and contrast, and then it start really falling off fast. You can't even keep up, until one day it goes POP. Mine made a mess as it shattered the glass. But replacement is easy, and it works fine with the new bulb. I only got 2000 hours out of my Sammy, so if your got 4000 I feel better. Honestly, that has delayed my projector purchase as I a think the tech needs to mature a bit. Now they are using LEDs and lasers which don't die.
