Question about InFocus ScreenPlay 4805 Multimedia Projector

Lately, all "white" objects, text, spaceships, etc. have "glows"

Hi -
I have a 4805 and have had so for a bout 2 years, (and not "overused" the light bulb,) in my opinion, but lately any time I watch DVD's, that have a lot of contrast, (Ex. the opening text scrawl on star wars) there is a glow around the letters,  -like a "bleed" of the color.

Another example is when I see scenes in space, ships or planets, they also have a "glow" around them as well - any hard light or bright whites, windows, lights, etc on screen have this glow - I have tried bright/contrast adjustement but even darkening down the image, I still see this effect -

Any ideas?

Re: Lately, all "white" objects, text, spaceships, etc....

Do you also have a glow around the projected image, try projecting on a white wall without any borders. The cause for this is dirt inside the lens elements diffusing the light.

Hi my infocus projector 4805 glass filter has fallen out, how do i fix it pls (ps i am a technologically incompetent female so need non techy language pls :)

Its commonly refered to as a Light Tunnel Failure. Go to and search for "4805 Light Tunnel" and you will finds threads on how to fix the problem.
If you have never opened the PJ before, there are 1-2 threads about opening the cabinet.
I also posted a DIY replacement solution that may help:

Infocus 4805 has yellow line on the right side of the screen

It will be the light tunnel. Apparently it is very common in the 4805. See here for how to fix it, by the way you cant get parts so its a DIY job.

InFocus 4805 - right 1/3 is fine, middle 1/3 dim, left very dim.

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

White Vertical line in the screen.

Again, this sounds like a light tunnel failure. See my other post about this.
I replaced my light tunnel with square brass tubing I picked up at the hobby shop.

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.

Good Luck!

I have a 4805 and have gone thru 2 bulbs in 3-4 years. When I changed the bulbs I cleaned with vaccum the best I could and not the upper corners of the image are darkening

Have you checked with the manufacturer regarding a firm ware upgrade? There was an issue with this at one point. Make sure to contact them directly. They can either mail you a cd version, direct you to where it might be on their website, otherwise email it to you.

They are able to fix that problem which my sister and my other sister/brother in law also owned this same pj had to do the same thing.

Let me know how it goes for you. Best of luck!

My projector can't handle white

Hi there

The next time you send your Projector for a service ask the technician to check the run rates on your colours as well.

It can unfortunatelly only be done properly in the Service Menu of the unit.
