Reiner,
Lamp life depends on many things including how well the lamp was made in
the first place. Don't forget to clean the filter often. If clogged, it makes
the lamp run hotter than normal, and that can shorten its life. A few other
things to keep in mind: 1. any time you turn the projector on, let it run at
least five minutes before you shut it down. 2. Don't unplug the projector
for several minutes (until the fans stop) after turning it off. 3. As with
any high temp lamp, never touch the glass with your fingers (skin oil will
cause damage).
If there is a "generic" number on the glass, you may be able to find a
replacement by doing a search on that number... but you will likely not save
much money that way assuming you can find just the bulb. Try www.bulbman.com
for a replacement. I have a service manual in .pdf format if you need it.
It's a big 'un... about 12 Megs.

Thanks again, Ray.

Last year you helped me with the service manual. By the way: I
couldn't fix the problem. I had to gave the projector away. The
problem was what I sugested - a fuse. But I couldn't find the fuse
within the projector, even with the manual. Nevertheless thank you
again.
