This is a very common issue with the Infocus projectors. Sounds like the mirror tunnel that sits right behind the Color Wheel and concentrates the light source onto the DLP chip. This tunnel which is shaped like a small prism is very fragile and can "fall apart" over time. Some have attempted to try and remove the tunnel and repair with limited success. Otherwise you may either need to send the unit in for repair or find a dealer who can order the part for you.
Here is another who had the same issue;

the light tunnel has collapsed and needs replacing. the part is inexpensive and relatively easy to replace. if you can get the part from infocus or an authorized service center (part # 306-0095-01), remove the top (4 brass screws and 4 silver screws on the bottom, 2-3 silver screws on the back), next to the lens is the colorwheel. remove the 2 black screws on the colorwheel base, 2 black screws on the metal tunnel frame side, remove the tunnel glass. replace, and reverse the instructions to put it back together.

your light tunnel has collapsed and needs replacing. you can get the part and do it yourself, or you'll have to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.

if it is over half your screen it is most likely the light tunnel under the colorwheel. If you have had it awhile the glue that holds the tunnel together deteriorates and they just fall apart. Or, the mirror inside the lens assembly may be knocked out of whack, but it's probably the tunnel.
