Are you speaking of the small prism shaped tunnel or the lamp itself? The prism or light tunnel may be accessed underneath the metal bracket that holds the color wheel in place. Be extremely careful as even breathing on this may cause it to collapse (ok, I exaggerate).

The picture is dark bluish green


if you shake the projector while it is on look at the picture and see if shadows move around all over, if so the light tunnel is bad.

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

I have an infocus in26 projector that has a shadow on one side of the image. i have been told this is indicative of a light tunnel collapse, is this a problem i can repair and if so how do i get the new...


it is the light tunnel. it is moderately easy to replace. just remember which screws go where. remove the lamp door, the top, rear and sides (8 screws on bottom, 2 in back). you'll see the colorwheel between the lamphousing and the lens. unplug the 2 cables for the colorwheel from the main board. unscrew the colorwheel base. the tunnel is under the metal clip next to the colorwheel. remove the clip and tunnel. replace tunnel and replace the clip, colorwheel, top, and lamp door. the top comes off as one piece, but must be replaced as 2 pieces. there are clips attaching the front to the top.

the part number for the tunnel is 306-0113-xx (if you have a in26+, it's # 306-0122-xx) and you can purchase it from any authorized infocus service center (find the closest one to you on the infocus website).

I need a new light tunnel for my infocus X2


Was actually looking up a different problem with an X2 and came across this thread.

I do electronic repair, and often do repair on projectors with this light tunnel problem. Probably 3 a week!

I came up with a solution about a year ago. It's a tunnel peice made of highly resilient carbon fiber, lined inside with extremely reflective mirrored stainless steel.

A company here in St Louis builds them for me and I go through quite a few!

If anyone is interested, feel free to email me at mhale@ahvio.com. I charge $50 per replacement tunnel (They are pretty expensive to make). Plus $10 for shipping to anyone in the US, unless you want to come by and pick it up.

I can include a extremely easy guide to install (Its VERY easy!)

These carbon fiber replacement tubes are a solid peice, unlike the factory that is just glued together mirrors :/ They are morons! haha

I've been using this replacement tubes for about a year now and installed well over 50, so I swear by them! Very resilient to heat, and very resilient to someone installing it that isn't very careful. It's almost impossible to break!

Also sale homemade LED super high flux projector bulbs for the X1, X2, and X3. May be able to build a bulb for a different brand, depending on what the current bulb is like.

These LED bulbs have a life of 40,000+ hrs and use very little power, and produce VERY LITTLE HEAT! Cheaper to build than the factory ones, at about $175 for a complete bulb with assembly. Have about the same ANSI output as the standard bulbs, I actually think it's a little more than the rated (like 50 more lumens or so~)
If interested in either, feel free to hit me up! Willing to send parts, or can do install myself.

Fixing an Infocus X2 Light Tunnel Problem...


Hi JF1226

This quite a tricky job , but not impossible.

You will see once you've taken out the light tunnel ( also known as the packlight pipe module ) that there is one or two of the small mirrors that has come loose as a result of the lamp's heat.

Glue them back with Super Glue that dries very fast.
Do them one by one , always try to build them back in from edge to edge i.e. - If the top one and left side one is loose , do the side one first and then the top one - just makes it easier.

Remember you only have one shot at this , so do it carefully.

Good luck and thanks for using Fixya.
