I strongly suspect a broken belt the covers need to come off.

Are you projecting an image at the time? Often times you can not keystone the blue background.
Mitsubishi xd250u DLP projector Disassembly and Lens Cleaning Here is a video of the internal cleaning of this machine.

There is a black and silver knob under the keystone label( right above the automatic label ) on the side of your projector. turn this knob counterclockwise to loosen the covering over the housing unit for the lamb. once the knob is loosened lift the housing unit off of the side of the projector. You wlll see the enclosure where the lamp fits into beneath it.
Make sure the power is off for your projector while doing so. Screw the lamb into the enclosure , then replace the covering and screw the black knob in clockwise until it tightens.

Try downloading it from internet.

Re Keystone 68 projectors:
I join the growing throngs of folks who wish to view their family archives in 8 mm before submitting the reels to the digitals for conversion. Doesn't anyone have an answer for us? I continue to search, if I find, I'll post.
