Proxima Ultralight ls1 home theater / presentation projector Question is below?

I got a proxima ultralight ls1 projector from a friend. I turned it on and the color is off. It displays a pinkish tint at the top right and a green tint on the bottom. I tried changing the color settings but I can’t get it to look normal. Is there anything I can do to fix it. Could it be the bulb or lens?
