SOURCE: Color not correct on project

Hi there

You will have to find your nearest InFocus repair centre.

But that said , it is the most expensive part on a Projector to have repaired , because they will have to replace it.

My advice would be to rather purchase a new unit.

SOURCE: We have used our projector

Hi,

Are you using component video inputs? You could check the green connectors on both ends of the video inputs. They sometimes develop a poor connection. I would not throw a lot of money at it. It was a good projector in its day but they sell used on ebay or craigslist for $100 - $300 now.

Hope this helps,

Wide screen monitor distortion
Depending upon the screen resolution that has been set in Display, the image will be distorted on these large wide screen monitors.
To correct this distortion.
1. Create a large circle image using a draw program such as Paint (hold down the Shift key as you create the circle as it will draw a perfect circle).
2. Open Control Panel - Display - Settings tab and adjust the Screen resolution slider, increase or decrease the screen resolution then bring the circle image to the front and check the image, if the circle is still distorted then change the screen resolution and check the circle again until you are satisfied with the image of the circle.
3. When you are satisfied then click apply.

Mitsubishi flickering white lights on screen


this sounds like a bad optical light engine, the spots will only continue to grow in number.

See typical engine for this brand, lens on left is where image comes out and is directed on the screen.

3LCD Projection TV 2.5 years old displaying blue hue/blobs


I would first try a new lamp. If the reflector portion of the lamp has any defects, it could show up this way as the light would not be uniform. The next possibility is a defective light engine. The engine portion if not field repairable and would need to be replaced. Try the lamp first and let us know what happens.

Image has big yellow


Hi Zenmast

This is a burnt LCD that will need replacement. If the circle is yellow on a white screen , then it is your blue LCD that will need replacement.
