I've had my InFocus Screenplay 4805 for 3 years and it has done 1600 hours. Last night I was watching a film and there was a load snap. The projector kept running ok but the red part of the spectrum seems to have been washed out. Any thoughts - thanks. Geoff

Re: InFocus 4805 lost red
Yes Geoff, What has happened is one of the two red glass filters on the color wheel has separated and flew off which was the snap you heard. So white light is in half of all parts of the spectrum that require any red.
There should also be a vibration now that can be felt on the projector and possibly heard as well. I suggest not running it again until this is repaired as more damage could result. If you have the skills and the part that flew off isn't destroyed it can be carefully glued back in place and problem solved. I have seen quite a few of these glass filter segments survive this.

the light tunnel is collapsing and needs replacement. the part itself is relatively inexpensive, but you have to be careful if you want to replace it yourself. it's under the colorwheel, which is delicate. when you remove the top, front, and rear panels, remove the colorwheel (which is between the lens and the lamp) and carefully set it aside. there are 2 screws holding the light tunnel bracket in place. remove them and the bracket. pull out the pieces of the tunnel (little rectangles of mirror) and replace with a new one. reverse the steps to put it back together. by the way, you can get the part from any infocus authorized service center (check the infocus website for the one closest to you). part # 306-0095-01
Is this the first lamp you have placed into your Infocus pj? If not, did you reset the hours when you did it last time? Otherwise that can also confuse the projectors internal system thinking there is NOT a new lamp in there and there for make it stop working once the clock hours are expired and over the 3000-6000 suggested hour life.
Let me know so I can help trouble shoot other possible problems.
