Let me start by saying that my projector is an InFocus Screenplay 4805, but that I have had the shadow you're talking about on the left foot or so of my screen for about 18 months now. I've researched it and found out that it has something to do with the glue holding something called a "Light Tube" in place heating up and essentially becoming liquid enough to allow this light tube to shift positions...the further out of position it gets the more of that "eclipse" effect you see on the screen. It sound like yours has shifted far enough that no light can pass through it at all.

Projector picture has a darkened quarter screen on a angle


Ok I guess you have an optical mirror chamber error sounds good doesnt it but can happen if projector has been knocked or dropped in the optical engine there is a chamber connected in between the main lamp and internal glass lens you may see it if you look inside the lamp assembly this very small chamber has four very small mirrors in it and is held in place usually by a metal plate bracket you may find one of the mirrors has moved or dropped this makes the refraction of light incorrect which will cause your dark shadow on your image screen

hi,
First of all check the lamp hour of projector. just reset the lamp hour and try again.
1. Press the menu button
2. Select system
3. Then select lamp reset
4. Select reset
The lamp hour will be retested.
Try to do this before you projector turns off. it is recommended that do this only after replacing the lamp.


If doesn't work then check the following
Check the lamp cooling fan of your projector . may be its has some problem. its not running at the correct RPM. Do one thing, Remove the fan from the projector. In the fan there will be a specification sticker. Remove the sicker. now you can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. u can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the projector. power ON the projector and watch.
ok

Why does the projector keep going to standby mode?


If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.

1. Insert the power cord plug into the wall outlet and then

press the MAIN POWER switch.

2. Press the POWER button so that a picture is projected onto

the screen.

3. Press the MENU button to display the menu screen, and

then press the F or G button to select the OPTION menu.

4. Press the ENTER button, and then press the F or G button

to select LAMP RUNTIME.

5. Press and hold the ENTER button for approximately

3 seconds. The confirmation screen, "LAMP RUNTIME

RESET." is displayed and select OK.

6. Turn off the power.

This will reset the cumulative usage time for the lamp
unit to zero.

Actually you can turn the projector on and then tilt it in all directions and see if picture shadowing changes. I have experience with this issue on DLP TV'S. IT sounds like a light tunnel problem if you can see partial picture behind shadow. It is fixable but very tedious. But can be done. Do you have a picture of the problem that you could send over? Thanks Jay
