SOURCE: Infocus LP70 - It's all Green
A tinted image (whether green or another color) is almost always a symptom of a bad or damaged cable - or a loos cable connection. In your case, you'll likely need a new M1 to VGA cable (Part# SP-DVI-A-R).
Assuming that you've made sure that the cable connections are solid at both ends, there is a simple test to verify that this is a cable issue and not a costly projector issue. While the image is tinted green, open the menu. If the menu colors appear fine while the rest of the image is still tinted green it's the cable.

This is definetly the light tunnel issue. After searching and a million phonecalls, I tracked down a place that you can buy the light tunel for $41 on their own and simply put that in, making the projector good as new.
I Have the phone number of the place and also the link to the forum giving you fully pictured diagrams of how to change the light tunnel, and also I have a service manual if anyone would like it to be sent to them.

the light tunnel is collapsing and needs replacing. it is very difficult to do on your own with out the proper setup. you can send it in for repair, but it'll take them about 1 1/2 hours. the part itself is not expensive. try av solutions in ny. they're pretty good. www.avsolutionsny.com
