Place a white piece of paper about 1000mm in front of the screen and focus the image sharply.
Choose menu, image, advanced then select color manager.
go through the color options and check if some pixels are permanently on or off (ie small dots or black) instead of a uniform colour on the screen.
hi, first of all check the tint setting on your projectors picture menu. if not get the correct color then, your projector is a dlp projector that means it have a color wheel in side. if the synchronization of color wheel is not correct this problem can occur. there is a sensor for couting the rpm of color wheel. also have a black mark on the color wheels rotating portion. the sensor scene this black mark for making count. if there is any dust in that portion it will make difficult to the sensor making the counts. you have to remove the color wheel to clean the same. i have added a video how to clean the color wheel . not the same projector. ok
I have found that vertical lines that suddenly appear from projectors are due to poorly connected cables. Sut off your projector and wait for the fan to go off. Then unplug the connectors from the computer to the projector and secure them again, making sure to go all the way. Hope this helps.
I have the same problem as philvo. I was watching, the projector was operating normally, I heard a snap, there was a flash of light behind me I believe, and my Mitsubishi XD300U projector went to a black and white picture. That is all it will show now. All lights show normal operation. I would like to know if it is worth getting repaired. Does anyone have any ideas?
If you're getting a black and white image with or without source, it's probably the color wheel. Do you hear anything loose inside the projector? if you do it's the glass fragments of the broken color wheel.
