Replace light tunnel infocus 4805

SOURCE: Infocus 4805 problem

Make sure that the lamp plug is properly plugged. 3 flashes indicate this or a faulty lamp.

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).

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 [email protected]. 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.

It sounds like you have mounted the replacement light tunnel incorrectly. It is a common error. What has happened is you have the light tunnel sitting on yop of the positioning stop which is opposite from the color wheel side. If you take it back apart you will see that it's not laying parallel to the casting. if you reposition it so it is just touching where the opening is in the clamp on the color wheel side you will feel it fall into place.
