Color distortion in the projector is a common problem that is generally related to polarizers. So, the first thing that you need to do is to check if the polarizers are correctly placed. You need to see whether they are tilted at the same angle or not. If they are not, you should re-position them. This is the first thing that you should do. If you are not sure how to position them, you can ask for help from someone. Another thing that you can do is check if the polarizers are warped. If they are not, you need to buy new ones. If the problem persists, then you need to contact your service provider. This will help you to fix the problem.
