Today when I turned on my BenQ W100 the picture was noticeably dimmer than it ever has been, even 12 hours before. I can't find any setting to correct it, and even switching off eco mode (which I always use) make litttle different. It's difficult to say, but I think it's about half as bright as before - too dim to watch comfortably even in complete darkness. I've had it about six months and the projector says the bulb has been used for 888 equivalent hours. I was expecting 2000-3000 hours out of it. I think it's been treated quite well apart from my missus once accidentally cutting the power. I had it running 10 seconds later and didn't notice any immediate effects (that was about 3 months ago). The manual isn't much help. There's nothing on the care instructions that I don't do, no suggestions for things to clean (other than the lens) and no troubleshooting information for these symptoms. Do I really need to get another bulb after getting less than 1/3 what I'd expect out of it? Do you think it's worth looking into the warranty?
