Rick, I don't think you understand how it works. :)

The backlight of an LCD monitor isn't strong enough to project all but the 
faintest amount of light through the lens system.  By removing the LCD 
panel from the case, you're allowing the incredibly bright light from the 
projector to "be" the backlight.  The fan is needed to prevent the 
incredibly intense light from the projector from doing damage to the 
delicate LCD panel.
