Projector Image is discolored
This is one of the common issues found in Projectors and it cannot be resolved by replacing the lamp. For example if your projector shows a red, yellow, blue or purple tint along all or any part of your image, it needs a service from professionals. This type of discolored image indicates an issue with the polarizing plate for LCD projector or color wheel in case of DLP projectors. If we found this issue early in LCD projectors then it requires only cleaning or recalibration of color module. But if we neglect this and wait too long then this repair will be costly and involves replacement of prism assembly or polarizing plates.

Projectors need cleaning on annual or semi-annual basis if neglected then it will be shown on your projector image as dots or specks mainly this happens due to dust within the optical section. If the dust is settled on the colour module then the dots will appear as a tinted colour or hue, in this case the polarizing plate in LCD projector need to be cleaned or the colour wheel in the DLP projector needs to be cleaned.

Sometimes if the projector shuts off unexpectedly then there can be an issue with the ballast, cooling system, software or power supply. Rarely there can also be a damage in the internal circuit boards. In this case the repair will involve finding the cause of this problem and thorough cleaning of the cooling channels.
