Your sensor could be damaged or just dirty. It this is the case, you have an option the manually clean your sensor (a option that keeps the sensor optics open). Check this link if you want more information. http://www.ehow.com/how_5805668_clean-cmos-sensor-d30-canon.html

Tip

Mirror or light tunnel collapsing


A weakness that you might experience with your projector is the collapsing of the light or mirror tunnel. Not sure if this is common to DLP projectors only. The symptom is that you see grey bands or shadows on the edge of the TV image - this is caused by a mirror getting in the way of the bulb light. The glue holding the mirrors together seems to weaken over time (3000 lamp hours in my case) and causes one or more of the mirrors to loose its position. For solution, search for "mirror tunnel" or "light tunnel" under all projectors. The problem seems to be quite widespread. I managed to fix my LG's.

I wonder why the manufacturers don't use a rectangular glass tube that is mirror plated on the long sides ?!?! Suppose they want to sell new projectors after lamp or mirror tunnel expiry!

Shadowing on lower right of screen on InFocus LP70+


the light tunnel (like a square tube of mirrors) is collapsing. it needs to be replaced, but it's a bit involved, so and infocus service center would be your best bet. if you wish to try it yourself, let me know.

Color Alignment


the most common problem when the tv felt is the shadows all over the screen (maybe the tv didnt show it imm but looks like now is there the problem)
second:there is a circuit in the tv that works when the tv turns on every day. prevents the tv showing shadows on the screen.
the answer is this: if that system that prevents shadowing is working then the CRT is broken and say bye to the TV. But if the expert tech can make sure the D' gauss system is not working and can repair it then you get tv back.

Shadow on Flat Screen TV


Projection TV correct? This may take some work but it is common for a spec of dust to settle onto the Mirror inside the TV, The back side of the TV screen or onto the Lens from which the Video image is projected. Some TVs have ports that allow you to access the inside of the TV from the side, others you must remove the screen.

This is not something to do every day or every week and it will not improve the picture. You only do this when you notice that it is dirty. Any more than that and you yourself will create a bigger problem. ONLY LIGHTLY DUST the screen. Soaps, water and windex will leave streaks, damage the screen and cause more trouble.

Projection TVs are the eqivalent of a big flashlight showing onto a wall. Put you hand in front of the light and you get a shadow.

Inside you TV there is a light (the TV picture) that bonces of a mirror attached to the inside of the back of the TV. The light reflects off the mirror onto the back of the screen. You view this refelected image from the front. Spiders commonly make webs inside the TV that appear in the picture. Dust Bunnies may get blown into an area and become stuck in the way. Sometimes a lite tap, shake or blow may remove this also.

A black shadow half way down the frame


http://www.lotek.nu/misc/EOS_300D_sub-mirror_repair/

2 cent plastic pin holding AF sub-mirror broke. See above. Unfortunately Canon charges a bit above 2 cents to fix it. Saving pennies on plastic instead of metal will make Canon a boatload of money because they will all break eventually. Of course if everyone changes manufacturer on their next camera this might backfire.

Shadow on image


The camera has a main mirror that you see with the lens off and a sub-mirror underneath the main one. It may be the sub-mirror is not flipping up completely when you take a picture. It could be off its hinges or damaged. Any good camera repairman in your area should be able to confirm this

1/2 the screen is viewable


You would be wrong. Lamps do not do that. They either work or they don't, they do not cast shadows or give half an image.

What is going on is the light tunnel has failed. It is a small, 4-sided mirrored tunnel that focuses the light into the optical chamber. It is directly behind the color wheel. I've seen this probelm dozens of times.
