There is no products available to see on this website. We just offer services with offering solutions.

If you are looking for legitimate e-tailers to purchase from I'd suggest to check out visualapex.com or go off of the manufacturers website for product orders.

Thank you and let us know how it works out for you.

P.s. gluing is indeed not a good idea...Have you contacted a manufacturers service center to have it serviced or checked out from a specialist?

Half of the screen is dark. Tried a new bulb wilth no effect


Sounds like Light Tunnel Failure. Very common. Biggest problem is that a replacement part is almost non-existent and a manufacturer repair is expensive.
You can get further details on the problem at www.avsforum.com. Just search for "4805 Light Tunnel" and you will find threads about DIY repairs.
I also recently posted a DIY Replacement thread for anyone willing to make their own tunnel:

We have a screenplay 4805 by infocus. the right third has a dark shadow over the picture? the picture is lightly visible thru the shadow.


the light tunnel under the colorwheel has collasped or the projector has been jarred, knocking the mirror inside of the lens assy. out of alignment. Either way, it will have to be repaired by a technician.

How difficult is it to fix a collapsing light tunnel?


The replacement bulb is over $200 (maybe even more than $300).
It is a "halide" bulb that gets very hot.
Do not glue it; the glue (even when dry) will catch on fire.

Better to deal with it or consider replacing mmedia projector ($600)

Hope this helps!

New Problem after fixing Light Tunnel on a SP 4805


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.

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.

How much does a light tunnel repair cost?


Hi there

The light tunnel is not a expensive part to have replaced and it is better to do it than to keep on buying new lamps.

You can easily find your nearest Authorised Service Dept online.

Tip : Don't let just any monkey do this type of work on your unit , rather pay a bit more with the authorised agents.

Problem with my 4805 projector


Yes, you are describing a light tunnel failure and it can be repaired. The parts are available, I just don't have any on hand right now. I will be ordering more this week. The part is about $40.00 plus shipping. The repairs can be challenging if you are not experienced. The color wheel has to be removed to get to the light tunnel The light tunnel is very fragile and easily broken.

Glass prism


Greetings,

Thanks for contacting us regarding your product questions or concerns. It appears you are wanting to know how to reach the glass prism from your 4805?

My initial question would be, why are you looking to access the glass prism in your 4805? This is a very dilicate process internally of your projector which helps it opperate. Are you trying to self-repair your projector?

Let me know. I'll be waiting for your reply.
