Hi rlamon,

Sounds like a image burn in which is not good and may require servicing of your unit. But for I suggest that you try to reset the projector, most projectors have reset switch, so try it. Also leaving the unit off for a like a day without using it may help to clear the burn in.

Also try to test the projector on other inputs like connecting on a computer or dvd player, and check to see if the faint image is still there. Sometimes it helps to clear those burn in if use a different input or a screensaver.

Hope these suggestions help!

Peace! :)

A static shadow on a projector can be caused either from a foreign object (some part that had moved) between the lens and the lamp, or more probably from a mirror that had moved in the light tunnel.

In a projector, light generated from the lamp is projected trought the light tunnel (a square section tube covered with mirrors on the internal sides), in your case one of the mirror had probably detached, and that is causing the shadow. Otherwise, either the light tunnel, the lens , or the lamp are out of place.

To fix this the projector must be taken apart, and inspected inside.

Sounds like your Mainboard will need repair or replacement if you only get a faint image...

Check if the unit is still under warranty as this could be a costly exercise.

    For now, you can try to do a through cleaning and try to dust out the light path. 
    I do not know how deeply you want to dig into the thing but if you can get to it make sure the optics are clean. 
    Also look into the optical path while it is off and try to locate any weird films or dust. Sometimes hard to spot I know.

When I first started the game I think remember downloading a update. But I think it was a roster update. How do you download the up date?

This is a three man franchise league. When we got to week 17 of the first season and played our games, that was the last time the franchise would save. After reaching the playoffs playing my game the franchise would not save at all. It would freeze up. Then if you try to simulate the playoffs. It would freeze up. After playing with it we were able to get to the end, but when advancing to the off-season it would freeze up. Finally, figured out when we got to pro bowl to save it and it worked no freeze-ups. We were able to advance to the off season after that, did all off-season stuff and got to the preseason. Now when trying to simulate preseason it will freeze up. What the heck.
