Yesterday, the 1800 hour "Replace Lamp" message popped up. It displays for a few seconds after startup and then disappears. IIRC, my manual stated that at 2000 hours, the projector will run for 10 minutes, then go to stand-by. The thing is, the image still seems quite bright to me. I'm sure that if I changed the lamp, I'll probably notice a difference in brightness, but right now, it looks fine. \n\nSo, my question is: is there any harm in resetting the lamp clock back to 0 hours and just keep using it until the image is unacceptably dim, or the lamp fails completely? I have a spare lamp on hand, but I don't want to use it, if I don't have to.
