Infocus 4805 problem

I have re-glued the light tunnel after shadow problems.I cleaned and reassembled the unit. The projector operates as it should except the fan comes on at high speed although it is on low power, then runs fine for 5 minutes, shuts down and the led flashes three times. Help!

Thank you

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

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.

It has a shadow on half the screen


the light tunnel has collapsed. you can get the part from an infocus service center and do it yourself or send it to one for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

Dimensions of light tunnel for infocus 4805??


if you're intent on gluing one together or making one yourself, that's a bad idea. if it's off by a fraction of a millimeter, it's be obvious in your image. if you get the part new it's under $20, and replacing it is easy. just get one from an infocus service center, like av solutions in ny. they're really good. www.avsolutionsny.com

I have shadowing on the edges when in wide-screen. When in normal screen the image is fine. How do I get rid of the shadow? Also, is there a way to clean the mirror inside the unit?


the only way to properly and safely clean anything inside is with canned air. as for the shadow, replace the light tunnel. you can get the part from an infocus service center and replace it yourself, or send it in for repair. either way, try av solutions in ny. they're really good. www.avsolutionsny.com

I have a InFocus 4805. Half the picture is darker


Your light tunnel may have collapsed. This is made up of 4 tiny rectangular mirrors glued together to make a tunnel.

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.

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.
