Question about InFocus ScreenPlay 4805 Multimedia Projector

Open Question

Projector lights up, but only half of the picture is clear, the other half is obscured, there is a (yellowish) line in about the middle. Left side of that line is projected but behind a dark veil.

We found the problem after a shift of venue. The projector was taken down from its mounting, stored and then put up in the new place. It was also mounted when building alterations were happening and then cleaned out with compressed air.

    Hi Leonie Rousselot, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box?

    Was there anything on the projector bulb itself?

    Thank you all for your efforts. We tried overscan, tracking, phase, horizontal position and vertical position, but all those things only moved within the projected field but still has this overlaying dark veil that doesn't move, about half the screen, vertical.

SOURCE: Faded Black Strip on Side of Projection

I had a similar problem with my InFocus LP600 although my black stripe was straight up and down. I am guessing this is caused when the unit is bumped or dropped. This is not an easy fix unless you have a lot of experience with small tools and parts and you may need an extra set of hands. I found some tiny alignment screws under the lamp cover and hidden beneath a peel-off 0.5" x 2" black plastic strip. The screws are located between the bulb assembly and the main projection lens and are oriented 90 degrees apart around the light projection path. The trick is in getting the projector to temporarily function with the lamp cover off -- it has an interlock tab on one edge that pushes on a microswitch when closed. We turned the projector upside down but raised on some slats for heat dissipation, gently held the interlock switch in with a small screw driver, and plugged in the power cord. After pushing the power switch to get the image, I adjusted the tiny screw that is angled towards the front of the projector and the stripe dissapeared! Since your stripe is angled, you may need to adjust both alignment screws. The screw heads are very tiny torx bit types but I was able to use a 3/64" (.05") allen (hex) wrench that came in a set of cheap jewelers type tools that are widely available. Be very careful while operating the unit with the lamp cover off as there are very hot surfaces and exposed wiring.

Sounds like the LCD inside is dying and you're losing pixels. Bummer.

Viewsonic PJ1173 displays yellowish pictures, dont know wat to do


I presume that the problem started in the middle of the picture and has gradually got larger as time goes on.
It is most likely the blue organic polariser/filter glass plate that passes the blue light into the blue lcd panel.
If you were to take the cover off ( with the power disconnected) and check inside the optics area, you may see the filter burnt from long use on high brightness levels.

Either try and get a replacement polariser or buy a second hand PJ1173 cheaply on ebay and replace that part.

this projector does not have lcd's. it has a colorwheel and a light tunnel. the light tunnel has probably collapsed and needs to be replaced if you have distortion in the middle of the display. if it were to one side or the other or a the top or bottom it may have been adjustable. But wiith it being in the middle, I'd have to say you needed a new light tunnel.

Dark in middle , clear in upper and middle left corner


your light tunnel has collapsed and needs replacing. you can get the part and do it yourself, or you'll have to send it in to an infocus authorized service center. try av solutions in ny. they're pretty good.

Lp70+ display shows a solid black vertical line


the light tunnel is either collapsing and blocking the light going through it (and needs replacement) or the vertical/hoizontal adjustment of the tunnel. if you take the lamp out and move the colorwheel (with a pencil eraser) to the clear section, you should be able to see a square through it. if part of the square is blocking the middle, the tunnel needs replacing.

by the way, on some projectors the light tunnel is called an integrator rod.
