Question about InFocus ScreenPlay 4800 Multimedia Projector
I noticed you helped a few people with the SP4805 and I was wondering if you knew how to fully take one of these apart. I can not find a free repair manual for the life of me...
The problem I am having is there are a couple of spots where the color is slightly distorted (most noticeable on white where it has some gray spots) I figure it is some dust that has accumulated on a lens of some sort as that was the problem on other projectors I worked on with the same problem. But I can not get the thing fully open.
So my question is... do you agree that is the problem? and if so how do I get that thing open. I can send pictures if need be.
With the image shown, use the lens to focus on the spots. if you can, it is dust. if you can't, you have a colorwheel issue. to take the top off: remove the 8 screws on the bottom (4 brass from the bottom middle, 2 silver from front bottom, 2 from rear bottom), 2 or 3 on the back. use a small flat-head screwdriver to undo the clips through the top vent on the back panel and remove the panel, unplug the wires fron the left and right sides, pull the top up and forward taking front with it. blow dust out with dry compressed air.
