The projector come on but does not show a picture. the screen come up bright white with no image.

Hmm, that's interesting. When you use your remote control to select a different input source, can you see the different source codes showing up on your screen (like TV, Input 2, Input 3, etc.)?
If you can see that, it means that something is being transmitted to the screen (that's a good thing). If not, it probably means you'll need to call for service.
