My old projector shows green background
i am not so sure, whether i am in right subtopic, or not. I am sorry, if i am in wrong one.
My Friend has gave me a old Projector, Panasonic PT-L720E. It is not bad. But shows green background. It is remarkable, if screen is black. otherweise it is not remarkable.
Why there is green background? If its possible, how can i prevent this.
I am not quite familiar with projectors, but i am good with electrical devices.
