I have searched the forum and have found discussions on using a slide projector with 1.8"-2.5" LCD panels. This appears to be the simplest application of slide projectors. Now, without trying to preserve the whole machine, can the optics be salvage for use with, say, a 7" display?
Hmm...
Sort of thought this would be an easy one for the gurus.
Basically, I can get two of these projectors for relatively cheap, and I was wondering what parts I could salvage for use in a video projector. any ideas?

no
Slide projector optics are only useful for tiny LCDs. Don't bother. Even if you find a small enough LCD, the resolution, contrast ratio, and response time will be so bad it is not worth the trouble.
If you want to make a very low-end projector for watching videos, start with a hacked PSone & a big CRT projection lens.
For a very nice small format projector, start with a Lilliput monitor.
For a good large format projector, start with a 15" LCD computer monitor & a video-to-VGA converter box.
Either of the last two can give you very nice results, with lots of available metal halide lamps, reflectors, fresnels, projection lenses, etc. If you connect one of these projectors to a digital cable box, sattelite TV box, or DVD player with an S-video cable, you get an image that looks like HDTV in 4:3 format.
