Dark blur/"burnt" smudge look on screen

Great unit, no problems until recently when the right side of the screen edge became a dark "dirt" colored smudge, about 3 inches thick, now, another "smudge" across the bottom half. the bulb is relatively new and have not had any problems

Why is my Sony 3lcd projector not showing the color red?

I hope its on warranty because that sounds like a circuit board problem. Was the replaced lamp the original specification?

We have a Mitsubishi sd200u projector.The right side of the screen is dark,there is still picture but very dark.We thought it was the bulb,ordered and replaced that,and we are still having the same...

Does the dark side have a well defined straight vertical edge or is it ragged and blurry.
Is the picture still visible in the dark area, or has the picture disppeared and there's this darkness that has taken over.
I'm thinking that the optics may have been jolted. Has the unit suffered any impact or the like.

On the left side of the screen the red color is bleeding off the other colors and causing the picture to be blurred. It is not across the entire screen. Just on the left portion. Do I need a new bulb or is...

That is *not* a lamp problem. Definitely sounds like you have a some sort of video processing problem with the red signal. Just to be safe, try a complete factory reset in the menu. Sometimes, the auto-sync and other such functions cause the image to distort. This can happen if the projector is used with multiple image sources and the unit has to resize the image--it does this using mathematical algorithms. If resetting doesn't help, you need to explore repair options...remember, the unit has been around for awhile--shop around the search engines for quotes.

Dark area on right side of screen, just showed

I am Brasilian and i don't speak english very well, so sory. A friend had the same problem,and other friends too.

The mirrors and the Color Wheel of the Infocus sp4805 are atached with fragility by glue that with the high temperature and humidity deteriorates. The detachment of the color wheel or the mirrors drivers of light produce dark spots. It is easy to solve. Just paste again, but should be done by specialized professional.

This can be a fault with the lens or the imager. It is hard to know without doing some tests, and trying a new lens and a new imager.

No color

Color wheel disc is broken and not repairable, problem is unless you know someone that can get the part you have to take your projector to an authorised service centre.

Infocus 70+

We have had similar issue w/ multiple LP70+ projectors. The units get to be 1-2 years old and suddenly the right vertical edge of the display is distorted. There is usually a shadowed vertical bar that clouds about 3-5% of the horizontal space from the right edge.
What's the cause?

Blue on one side of the screen.

as a first step, check for dust and dirt in the optics of the unit, sometimes they can cause these kinds of problems. if not, Look at the filters attached to the blue LCD panel. If I remember correctly it has a dark "yellow" mirrored surface. I have had one go bad and give the same symptoms. It looked like it may have had an optical flaw that "captured" the intense light rather than passing it thru it. As time passed it got worse. The replacement filter fixed it.
