SOURCE: 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.

such as this situation, you had better buy a new light tunnel for infocus sp4805,
generally, the manufacturer did not directly sell parts to end user, and always ask you send machine to customer service station. then applied for expensive service cost.

actually, you can find a reliable parts retailer, can get a cheap parts from them.
such as the infocus 4805 projector oringal light tunnel only cost USD79 with shipping to all over the world.

I have an InFocus ScreenPlay 4805. it only shows part of the picture. the rest of the screen have lines and is fuzzy. thanks herman


One possibility is that the Mirror behind the lense is dirty but I think that this also may be the light tunnel issue that I explained in a couple of other posts about the SP4805.

Dark area on right side of screen, just showed


I am Brasilian and i don't speak english very well, so sory. A friend had the same problem,and other friends too.

The mirrors and the Color Wheel of the Infocus sp4805 are atached with fragility by glue that with the high temperature and humidity deteriorates. The detachment of the color wheel or the mirrors drivers of light produce dark spots. It is easy to solve. Just paste again, but should be done by specialized professional.

Infocus SP4805 buzzing noise


Hi dcabbarno

The buzzing noise is a broken colourwheel and the shadow could be a part of the colourwheel that is obstructing the light engine or it could be your packlight pipe ( tunnel with 4 tiny mirrors in it ) that was damaged when the colourwheel broke.

I do unfortunately not have the part numbers of the parts that I mentioned , but you could assist by opening up the unit and supplying me with the part numbers.

The colourwheel you will spot straight away once you've taken off the top cover of the Projector , the packlight pipe is situated right next to it - looks like a small tunnel that's got 4 mirrors inside it - takes the light into the light engine.

Once you've supplied me with these I can get you prices and places to order it from and will help you with instructins on how to replace them - it is quite easy to DIY.

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.

Hi there.

This is definetly the light tunnel issue. After searching and a million phonecalls, I tracked down a place that you can buy the light tunel for $41 on their own and simply put that in, making the projector good as new.
I Have the phone number of the place and also the link to the forum giving you fully pictured diagrams of how to change the light tunnel, and also I have a service manual if anyone would like it to be sent to them.

Cheers
Russ
