Projector Service Center your projector discolored Projector Image.
Projector image discoloration is one of the most common issues, and is not resolved by replacing your projector lamp. If your projector shows a yellow, red, purple, or blue tint along all or part of your image, it needs to be professionally serviced. A discolored image means that there is an issue with the color wheel (DLP projectors) or polarizing plates (LCD projectors). If caught early on LCD projectors, this repair only requires cleaning, labor, and recallibration of the color module. If you wait too long, this repair involves replacement of the polarizing plates or prism assembly which can be quite expensive.
