I have an used NEC LT240 which I would be happy to sell you for a good price. It needs a new lamp, which will run you about $400.

Help! I have had my DLP projector mounted for a few years now, with approx. 68% lamp life remaining on the original bulb. After approximately 15 minutes of viewing (any source), the screen flickers for a minute and then the image seems to become less vivid, almost as if the bulb is going to go out. Although I am supposed to have many hours of remaining life on the bulb, could it just be that this bulb is about to die? After the flickering and the image becoming poor, I have tried switching from Eco mode to full power mode. The image does get a little better, but it is certainly not what it used to be. If I take it in to get serviced, it will cost approx. $150 just to take a look. A new bulb is $200. Should I just take my chances with a new bulb? Thank you!
